Natural Face Fibres 100% Wool 80/20 Wool/Nylon Cleaning agents should have a ph in the range. Specialty Face Fibres Silk Viscose Cotton Flax These specialty fibres are found in our handtufted rugs and may be cleaned using minimal moisture and fast drying time. Excessive moisture or prolonged drying time will create physical and/or aesthetic problems that may not be correctable. Cleaning agents must have a ph in the range. As with any fibre/cleaning agent, pretest an area to test for colourfastness. While the rug is still damp, the rug must be groomed with a suitable grooming brush designed for carpets & rugs. Failure to groom the cleaned rug may result in an unacceptable appearance. Cotton Bath Mats - Cotton Bath Mats are machine washable. The key to cleaning and maintaining all carpets & rugs is Clean and Dry. Note: All cleaning agents must be approved by the Carpet and Rug Institute s Seal of Approval (SOA) Testing Program. A list of approved products can be found on the CRI website at Twww.carpet-rug.comT or contact Tai Ping Carpets for further information. Should there be any hesitation or doubt in the abilities of the rug owner, the services of an IICRC (Institute of Inspection, Cleaning and Restoration Certification) Certified Firm Employing Master Cleaning Technicians is highly recommended.

16 Maintenance Guidelines 2005 Vacuuming Routine vacuuming is essential for the proper maintenance of any carpet. This is best accomplished through the regular use of an upright vacuum with dual motors. The brushes and suction are driven by separate motors. Vacuums with beater bars are not recommended. Vacuuming should be performed at a rate of two feet per second for three to five passes over the same area. Vacuuming Schedule and Equipment Vacuuming takes time and commitment, but is the most cost effective way of preserving your carpet s appearance. Traffic Classifications Very Heavy Traffic Heavy Traffic Medium Traffic Light Traffic (>2500 foot traffics per day) Vacuum 1 to 2 times daily in traffic areas and overall 7 times per week ( foot traffics per day) Vacuum daily in traffic areas and overall 4 to 7 times per week ( foot traffics per day) Vacuum daily in traffic areas and overall 3 to 4 times per week (<500 foot traffics per day) Vacuum 1 to 2 times per week Note: All vacuums must be approved by the Carpet and Rug Institute s Green Label Vacuum Cleaner Indoor Air Quality Testing Program. A list of approved manufacturers and products can be found on the CRI website at Twww.carpet-rug.comT or contact Tai Ping Carpets for further information. Tai Ping Carpets Page : 4 October 05

17 Maintenance Guidelines 2005 Cleaning Frequency The following guidelines have been established by the Institute of Inspection, Cleaning and Restoration Certification (IICRC). They are to serve as guidelines on recommended cleaning frequencies for carpet from a public health perspective in addition to a traditional aesthetic concern for appearance retention. Carpet Owner/Maintainer Professional Carpet Cleaner/Restorer Traffic Soil Rating Light <500 Foot Traffics per day Medium (moderate) foot traffics per day Heavy foot traffics per day Very Heavy >2500 foot traffics per day Vacuuming Spot Cleaning 1 to 2 per week Daily or as soon as spots are noticed Daily in traffic areas. Overall 3 to 4 X per week. Daily in traffic areas. Overall 4 to 7 X per week. 1 to 2 X daily in traffic areas. Overall 7 X per week. Daily or as soon as spots are noticed Daily or as soon as spots are noticed Daily or as soon as spots are noticed Interim Maintenance (Between Restorative Cleanings) 1 to 3 times annually 3 to 6 times annually 6 to 12 times annually 12 to 52 times annually Restorative Cleaning 1 to 2 times annually 2 to 4 times annually 3 to 6 times annually 6 to 12 times annually Note: Although these are generally followed traffic-rating guidelines, users of this information should be aware that the condition of every building differs in traffic, soiling rates and usage. Common sense, experience and good judgment help dictate the best carpet maintenance program. Each individual facility should be assessed based on use, climate and desired appearance level. Tai Ping Carpets Page : 5 October 05

18 Maintenance Guidelines 2005 Maintenance Plans Long term carpet & rug performance and appearance retention begins with effective maintenance. Improper maintenance may reduce the useful life of the carpet. Not only is a proper maintenance program important for long-term performance, but the Indoor Air Quality is also improved. Test results show that carpet also aids in reducing contaminates in the breathing zone. Utilising approved vacuums, cleaning chemicals and cleaning methods, the Indoor Air Quality of the structure is greatly improved. Regular maintenance is a must. Soil prevention, vacuuming and spot removal should be included in the maintenance plan. Interim Cleaning Interim cleaning is a high-production, fast drying process used between restorative cleanings. The frequency of interim cleaning depends on traffic, carpet location, use and exposure to soiling. Restorative Cleaning Restorative cleaning is the process of extracting or removing entrapped soils and residues. Higher moisture levels, lower production rates and slower drying are characteristic of restorative cleanings. Drying It is imperative that the carpet be allowed to dry before foot traffic is allowed on the newly cleaned carpet. Utilisation of the HVAC system, in conjunction with portable air movers is a must. Preventative Maintenance Effective carpet maintenance begins outside the structure. Areas around entryways must be kept clean and free of any contaminants that may be transferred into the facility. The best way to prevent or decrease carpet & rug soiling is to not allow soil into the facility. Up to 94% of the soil found inside of a building comes from the outside. The most effective way to control unwanted soil is to utilise control or walk off mats at all hard surface entryways. It has been determined that at least six footsteps (18-20 feet) are required for efficient soil transfer to the entry mats. Walk off mats also help prevent slip/fall accidents from occurring on the hard surface areas. Studies show that 80% of all slip/falls occur on hard surfaced flooring, with 80% of those resulting in injury. Tai Ping Carpets Page : 6 October 05

19 Maintenance Guidelines 2005 Daily maintenance of entry mats is required. Soiled mats should be removed or replaced to eliminate the tracking of unwanted soil onto the carpet. Cleaning Methods Hot Water Extraction This is the recommended method for cleaning all 100% Wool, 80/20 Wool/Nylon blends 100% Nylon and Solution Dyed Nylon carpets manufactured by Tai Ping. Sometimes referred to as steam cleaning, there is actually only hot water sprayed onto the carpet fibres. The hot water and soil are then extracted from the carpet. A pre-spray is recommended prior to the extraction process. The pre-spray is applied with a common pump up sprayer. Agitation using hand brushing or mechanical brush action is followed with extraction. In-tank cleaning solutions should never be mixed in excess of the recommended dilution rates. When using a box & wand or truck mount Hot Water Extractor, one pass with spray and two dry passes are recommended. Dry Cleaning Methods Dry cleaning methods using absorbent compounds or crystalline drying agents can be used for cleaning all 100% Wool, 80/20 Wool/Nylon blends 100% Nylon and Solution Dyed Nylon carpets manufactured by Tai Ping. Caution: The rotary action of the Spin Bonnet or any rotary brush equipment may distort the pile yarn when and if the equipment is used improperly. Note: For all cleaning methods, follow the Institute of Inspection, Cleaning and Restoration Certification (IICRC) S100 Standard and Reference Guide for Professional Carpet Cleaning.

21 Maintenance Guidelines 2005 Carpet/Hard Surface Transitions Carpet adjacent to hard surface areas is susceptible to abuse from the harsh cleaning agents typically used to clean the hard surface. This is particularly true at kitchen or food preparation areas. The hard surface cleaners and cleaning equipment must not be allowed to come into contact with the carpet. Walk off mats are highly recommended.

23 Housekeeping, Snow Removal and Grounds Cleaning #S Exhibit III Attachment 4 Milliken Carpet Maintenance

24 Hospitality Markets Pattern Broadloo m Modular/Custom 201 Lukken Industria l Drive Lagrange, GA Milliken Carpet Dear Milliken Customer: Thank you for your use of Milliken Carpet. As you are probably aware, after the selection, purchasing, and installation of a carpet product, the key variable that continues to effect the beauty and aesthetic appeal originally exhibited by the carpet is the ongoing care and maintenance program. Milliken & Company has evaluated every major carpet care system in the market and has concluded that a properly executed program using Capture Dry Extractor is the most effective method to ensure lasting carpet performance and cost effective maintenance. In order to obtain optimum appearance retention results, we feel that a preventative maintenance schedule utilizing Capture should be instituted. This maintenance program should consist of the following: 1) Vacuuming Schedule: Vacuuming is the most important part of a successful carpet maintenance program. Moderate to heavy traffic areas should be vacuumed daily in order to remove the soil which collects in the carpet and leads to the need for cleaning. In order to best remove this soil, a commercial vacuum with the following specifications should be used. A) The vacuum should have a beater bar, preferably driven by a separate motor. B) The soil collection bag should fill from the top so that the suction of the vacuum is not restricted as the bag fills. In addition to a good vacuuming program, periodic pile lifting with a Certified Pile Brush is also strongly recommended as a supplement. The pile brush lifts and erects the carpet fibers and helps to prevent matting and crushing, especially in high traffic areas such as corridors. It also removes the heavier soils that vacuuming does not remove. When using a Certified Pile Brush, it should be pulled against the pile lay of the carpet in order to best restore the resiliency of the fibers. 2) Spot and Stain Removal: Inspection for spots and stains should be a daily program assigned to routinely remove all spots prior to permanent damage to the carpet fibers. Capture and Capture Prespray can be used to remove most stains encountered.

25 3) Carpet Cleaning Schedule: Carpet should be cleaned when vacuuming will no longer remove the soil. As this is dependent on traffic and soiling conditions, some areas of your carpet will soil much quicker than other areas. Because Capture is a dry system, it allows for these soiled areas to be cleaned as needed, without cleaning the entire carpeted area. 4) Milliken & Company has developed an international network of Certified Carpet Care Contractors that are thoroughly trained and audited in the proper care and maintenance of Milliken Carpet using the Millicare process. We highly recommend you consider the use of these professionals to provide the proper care of your carpeting. Their only business activity is to care for Milliken products using authorized chemicals and processes and their work is monitored on a continuing basis to ensure total compliance with our recommendations. The long-term performance and appearance retention is in large part determined by the carpet maintenance program used. The Millicare contractors provide the very best source for this care. Please note the enclosed listing for the contractor in your business area. 5) Certain situations will require a more aggressive and intensive carpet care program. Enduse conditions such as restaurants and other food service environments may exhibit grease and/or heavy soiling conditions. This can be the result of both tracking and airborne contamination. A thorough cleaning several times a year with an "enzyme" cleaner specifically developed for carpet and hot water extraction is recommended. 6) The use of "topical" fiber treatments is usually unnecessary with Milliken commercial carpet products. Milliken applies performance enhancer treatments to the fibers under strict and controlled manufacturing conditions that provide the best in durability and performance enhancements. Under certain conditions a field application of soil and stain protection may be recommended. Any products MUST be compatible with pre-existing protection systems. Please consult your local Millicare contractor for recommendations. 7) Milliken color and appearance warranties are based upon Milliken's recommended and approved maintenance methods and procedures. Non-recommended methods significantly increase the risk of permanent carpet damage which can result in loss of warranties. Damage to the carpet caused by improper maintenance or cleaning methods is excluded from warranty protection and is the responsibility of the buyer or cleaning firm. Hopefully, this information will be of use to you. If there are any questions, please do not hesitate to call. Sincerely, Wayne Anderson Customer Support Manager Milliken Hospitality Division

26 MILLIKEN CARPET MAINTENANCE RECOMMENDATIONS Milliken's Carpet Care recommendation is Capture Dry Soil Extractor as the primary care program. This should be supplemented with spot cleaning, daily vacuuming, and pile lifting when appropriate. The Capture Dry Soil Extractor is an advanced dry cleaning compound that will cause no damage to the carpet. It consists of absorbent synthetic polymer particles that are impregnated with a water-based cleaning fluid. This minimizes residue left in the carpet fibers thus allowing a more thorough and longer lasting cleaning. Milliken endorses the use of Certified Millicare Carpet Care Contractors who are thoroughly trained and monitored to ensure that your carpet receives the best possible care and that your carpet investment is protected. Milliken does not recommend the use of cleaning systems containing detergent or solvent base products. Our studies reveal that excessive resoiling occurs from the residues left on the fibers which result in accelerating the loss of acceptable appearance levels. Additionally, some products will permanently damage the dyes used to color the carpet fibers or severely damage the carpet fibers and yarns causing fuzzing, matting, and detwisting. Under no conditions does Milliken recommend the use of spin bonnet procedures or chemicals. Damage to the carpet caused by the use of non-recommended maintenance procedures or cleaning chemicals are excluded from warranty protection and is the responsibility of the buyer or cleaning firm.

27 SCHEDULED CARPET MAINTENANCE Cleaning Maintenance The removal of apparent soil. Cleaning takes place on an "as needed basis." A planned ongoing cleaning process designed to retain carpet appearance at a high level every day; i.e., no obvious soil build-up. The planning function in carpet maintenance is step number one. Facility managers and maintenance supervisors who understand this step can have acceptable looking carpet every day within an established budget. When The proper time to develop a carpet care program is during the specification process.

28 WALK OFF MATS The importance of carpeted walk-off mats in limiting the amount of soil tracked onto the carpet cannot be over emphasized! a. Carpet walk-off mats should be placed at all necessary locations, such as entrance ways, cash-registers, track-off areas, at salad bars, etc. b. Mats should be in good condition and vacuumed daily and laundered before excessive soil build-up occurs. c. Kitchens and dishwashing areas are potentially high contributors to carpet soiling, especially because they are not carpeted. At least two walk-off mats (six foot in length) should be placed between kitchen, dishwashing facilities, and main carpeted areas. This will ensure the removal of most of the dry and wet soil from shoe soles before serving personnel walk on the main carpeted areas.

29 PILE BRUSHING In addition to a good vacuuming program, periodic pile brushing with a Certified Pile Brush is also strongly recommended as a supplement. The pile brush lifts and erects the carpet fibers and helps to prevent matting and crushing, especially in high traffic areas such as corridors. It also removes the heavier soils that vacuuming does not remove. When using a pile brush, it should be pulled against the pile lay of the carpet in order to best restore the resiliency of the fibers. (To order a Certified Pile Brush, contact: Certified Chemical Company at ).

30 SCHEDULED MAINTENANCE PROGRAM In order to establish a maintenance plan, soil localizing areas must first be identified. These high traffic areas tend to control overall maintenance duties and determine cleaning frequencies. These areas are where vacuuming and periodic cleaning should be concentrated. Observation of these areas will determine the frequency of vacuuming and cleaning. I. Vacuuming Effective routine vacuuming is a must for good carpet performance. It is the most essential of all cleaning procedures. A regular vacuuming schedule must be established before the time that the carpet installation is ready for traffic. Moderate to heavy traffic areas should be vacuumed daily, even if soil is not visible. Severe soiling locations may require vacuuming two or more times daily. A. The vacuum should have a beater bar, preferably driven by a separate motor. B. The soil collection bag should fill from the top so that the suction of the vacuum is not restricted as the bag fills. II. Periodic Maintenance Objectives: To have the carpet at its highest acceptable appearance at minimum cost. Carpet should be cleaned when vacuuming will no longer remove the soil. As this is dependent on traffic and soiling conditions, some areas will soil much quicker than other areas.

31 Capture allows areas to be cleaned as they become soiled which delays or eliminates the need for a major overall cleaning. Areas which receive heavy traffic, such as lobbies, major corridors, and restaurants, will require a Capture cleaning every one to three month. Medium traffic areas usually require a Capture cleaning every three to six month. Light traffic areas are cleaned every six to twelve months. After the maintenance schedule has been in use for a period of time, its results should be evaluated and necessary adjustments made. Remember: Minimum cost does not always mean lower total costs as this could result in a decrease in the useful life of the carpet.

33 Subject MilliCare Book Basics of Cpt. Maint. Owner Stephen Lewis Date 11/06/02 The Basics of Carpet Maintenance Facility managers face different issues around maintenance. Indoor air quality. Safety. Product damage. Appearance. Scheduling. Budgets. Other health concerns. Proper maintenance will: Improve indoor air quality. Improve carpet appearance. Improve facility appearance. Extend the life of your investment. Problems include: Poor indoor air quality. Inadequate removal of soil. Recurring spills and stains. Product destruction. Poor overall appearance. Four steps to improvement: Prevention (Barrier system). Proper product selection. Regular vacuuming. A maintenance program. Factors affecting carpet performance: Fiber & construction. Pattern & color selection. Installation. Maintenance schedule. Maintenance system & the people who perform the work MILLIKEN & COMPANY PROPRIETARY & CONFIDENTIAL 1

34 Subject MilliCare Book Basics of Cpt. Maint. Owner Stephen Lewis Date 01/16/03 Soil is the chief problem: It is tracked in. Deposited from the air. Brought in by other methods. Prevention (it is easier to keep dirt out than to remove it): Clean sidewalks and entrance ways. Use effective walk off systems. Vacuum regularly. Food/beverage restrictions. HVAC maintenance. Interesting Facts: The very group responsible for maintenance and sanitation is the very group seen as a major source of pollution. These workers contaminate the areas they "clean" and add to IAQ problems. The equipment they use disturb the quality of air by stirring and blowing around and about. Vacuuming is the best form of maintenance Vacuum regularly. Select appropriate equipment. Keep equipment well maintained. Pile lift in heavy traffic areas. Effective maintenance systems extend the life of the investment Use methods that will not cause resoiling. Skill & technology go hand-in-hand. Provider should be trained in indoor air quality and use only products that are safe and effective. Provider should use methods recommended by the manufacture. Provider should be certified. Fact: The longer carpet lasts, the less it costs. Fact: Regular maintenance makes carpet last longer. Fact: Carpet costs less to maintain than other types of floorcoverings. Fact: Good environmental sense = good business sense. Fact: Soil is a destructive force. Unless it is removed, soil will discolor and eventually destroy any carpet MILLIKEN & COMPANY PROPRIETARY & CONFIDENTIAL 2

35 Subject MilliCare Book Basics of Cpt. Maint. Owner Stephen Lewis Date 01/16/03 Soil has tiny hard, razor-sharp edges that can pierce a carpet fiber. The soil that does the most damage is the soil you can't see Advantage of carpet is that it can look good on the surface, but can hide the worst conditions. Soil ground in below the surface is hidden or may not be visible. Unless hidden soil is removed it will continue to attract more soil. Sharp abrasive particles and friction (foot traffic) will flatten carpet tufts. A planned consistent maintenance program will: Remove abrasive particles before they damge fibers. Result in the carpet retaining it's original appearance longer. Reduce cost. Where soil comes from: Tracked in from sidewalks, parking lots, or from the street. Airborne (the same pollutants that are found outdoors work their way inside). Spills (they occur wherever you find people). Variables that effect soiling: Types of soil may vary. Traffic patterns and traffic volume. The carpet you specify. Carpet selection is important for long term appearance: Choose the correct color/pattern. Choose the right construction. Insist on soil resistant treatments MILLIKEN & COMPANY PROPRIETARY & CONFIDENTIAL 3

55 Introduction There are many factors that can affect the appearance of carpet including color, pattern, yarn fiber, and of course maintenance. Maintenance is important because a routine carpet maintenance program can preserve and maintain your floor covering and extend the life of your carpet investment. A routine maintenance program includes daily care such as vacuuming and spot cleaning, in addition to interim and periodic restorative cleaning by hot water extraction. Excessive soiling and stains may require that different methods, or a combination of methods, be utilized. However, even restorative cleaning typically will not bring back the beauty and appearance of the carpet if the overall maintenance program has been neglected. Routine care means a longer lasting product. However it is important to implement a maintenance program from the very beginning. Having the right equipment and cleaning solutions along with a properly trained technician is critical to the success of the program. An effective maintenance program is carefully planned and executed on schedule. Comprehensive Maintenance Program An effective maintenance program consists of five key elements: Soil Control containing the soil entering the building using walk-off mats at entrances. This includes outside matting, inside matting and mats at certain other high traffic interior areas. Ideally, walk-off mats cover about 15 steps. Interface offers many options for walk off carpeting. Contact your Interface AE for more information. Vacuuming - removing dry soil matter. Regular vacuuming is the single most important part of a carpet maintenance program. Spot and Spill Removal quick response to spills is the key. The faster spills are dealt with the less chance that they will become stains. Interim Cleaning used regularly, interim cleaning can put off the need for restorative cleaning. Restorative Cleaning deep cleaning designed to remove trapped soils. Hot water extraction is the most effective method and the only restorative method recommended by Interface. Identifying Your Specific Maintenance Needs Just as various areas of your office or building are subject to different uses, each area demands a different level of maintenance and care. Heavily trafficked areas such as entrances and corridors require more frequent vacuuming and cleaning. Areas around vending machines and desks need daily attention to spills and stains. Also certain areas may require different types of equipment to be used. A comprehensive maintenance program should have a chart or diagram of the building s floor space outlining proper cleaning frequency rates, methods and equipment. Implementing a welldesigned maintenance plan can add years of useful life to your carpet investment. 3

57 Maintenance Techniques An ideal maintenance program is designed to help prevent soil from reaching the carpet, and to remove soil before it causes damage. To keep your carpet clean and looking like new, such a maintenance program uses a combination of methods tailored to your facility s needs. Cleaning frequencies are based on the specific needs of trafficked areas in your facility. Preventative Maintenance Maintaining your carpet s appearance means more than choosing the right cleaning method. Choosing the right products up front contributes greatly to the overall performance of your floor covering. The use of walk-off mats helps keep soil from entering the building. Outside mats are designed to scrape dirt and debris off shoes while interior mats are designed to remove smaller soil particles as well as help absorb moisture. Interior walk-off mats should extend a minimum of six feet inside the entrance. At 15 feet, these mats can effectively remove 80% of soil and moisture before it reaches the carpet. Mats also can be effective in other interior areas including elevators, around water coolers and food station areas, and at stair thresholds. Walk-off matting should be maintained the same way as interior carpet using the frequency guidelines for Very Heavy cleaning based on the chart on page 4. Chair Pads Chair pads are NOT required with any Interface carpet. Vacuum Cleaning A good vacuuming program is essential to the success of your carpet maintenance efforts. Effective daily vacuuming reduces the frequency of periodic maintenance procedures required to maintain clean carpet. In addition to removing soil, vacuum cleaning also helps to lift and restore pile particularly for cut pile carpet. Proper equipment and technique are critical to the success of a vacuuming program. A CRI approved, dual motor commercial upright machine with cylindrical brushes should be used and set so that brushes are in contact with pile surfaces. Dual motor machines with independent motors for suction and brushing are preferred for this task. In most cases upright vacuum cleaners are advised. Dual motor vacuums with top loading soil bags and HEPA filters are also highly recommended. The Carpet and Rug Institute has a Seal of Approval program that grades various maintenance equipment including vacuum cleaners. For a list of certified dual motor upright vacuum cleaners see the CRI website at Canister, back pack type machines without brushes and riding sweepers with rotary brushes are generally not recommended. The frequency of needed vacuuming is determined by your comprehensive maintenance plan, but should be done daily. Heavy traffic areas such as lobbies, entryways and barrier mats, particularly those exposed to various weather conditions, may require more frequent vacuuming. Vacuuming these 5

58 areas more than once a day will help prevent soil from being tracked into other areas. The procedure for thorough vacuuming involves using slow overlapping strokes to make sure that the entire carpet surface is covered. Strokes should be no longer than 2-3 feet in length to avoid constant bending. Vacuum bags should be replaced when they are no more than 2/3 full. NOTE: FOR FLOR S AND SUPER FLOR PRODUCTS, A SUCTION-ONLY VACUUM IS RECOMMENDED OR IF EQUIPPED, USE THE SUCTION-ONLY SETTING ON A STANDARD UPRIGHT MODEL. Spot Cleaning Daily removal of spots and spills helps maintain the carpet s appearance between scheduled cleanings. Immediate action against spots and spills also reduces the probability of a permanent stain. It is important to use solutions that are appropriate for the specific type of spot or spill water based, oil based, or solids (including gum). Use spotting solutions sparingly and always try to remove the spot with water only before using a spotting solution. If available, using a portable extractor will significantly improve the ability to remove spots. Treating Water-Based Spots For liquid spills, start by blotting up as much of the liquid as possible with a clean white cloth. If the spill is semisolid or has hardened, gently scrape it with a spoon or spatula and then blot the spot with a damp cloth. Always work from the edge of the spot towards the center. Never rub across a wet spill in a manner that causes the stain or contamination to be spread from the original area. If spot remains after using water, refer to our spotting guide and choose the appropriate solution. Apply a minimal amount of solution to a clean white cloth and blot the solution. Rinse with water and allow the area to dry about 1 hour and then vacuum. Repeat the application if necessary. Protect the freshly cleaned area until the carpet is completely dry. Do not brush aggressively on the spot. Treating Oil-Based Spots When removing oily stains such as paint, grease, tar, asphalt, always check for color fastness by applying your cleaning solution to an inconspicuous area of the carpet. Spray or pour the solvent onto a white cloth and press / blot it onto the carpet. Check the cloth for any evidence of dye transfer to the cloth. If color transfer is evident, do not use the solution. If colorfastness is not a problem, apply your solution sparingly to a clean white cloth and press the cloth onto the spot. Again, do not rub across the stain, but blot gently from the outer edge toward the center of the spot. Repeat the procedure until the spot has been removed. Rinse with water and allow the area to dry about 1 hour and then vacuum. Protect the freshly cleaned area until the carpet is completely dry. NOTE: IF AVAILABLE, A SMALL PORTABLE EXTRACTOR MAKES THE TASK OF FLUSHING SPOTS AND REMOVING EXCESS MOISTURE MUCH EASIER. IF STAIN CANNOT BE REMOVED PLEASE CONTACT AN INTERFACE CONSULTANT. 6

59 Interim Cleaning Crystallizing Application (Encapsulation) The crystallizing method of maintenance is a low moisture procedure similar in some respects to the dry extraction method but instead of using the powder, a liquid encapsulation solution is used. Benefits include immediate access to the area without the necessity of extended drying time. We recommend XL North s GRAB Fortify LMC. Follow this procedure for crystallizing application: Thoroughly vacuum the carpet. Apply the encapsulation solution using an electric sprayer or a simple pump-up garden type sprayer. Agitate the carpet pile using a low moisture applicator with counter rotating brushes* to gently brush the solution into the fiber, dislodging and dispersing accumulated soil. Allow time for the solution to dry. Drying time will vary accordingly to several factors including humidity, air flow and air temperature but can normally be expected to be minutes. When dry, thoroughly vacuum again. NOTE: FOR FLOR AND SUPER FLOR PRODUCTS, HOT WATER EXTRACTION IS THE ONLY RECOMMENDED CLEANING PROCEDURE. Bonnet Cleaning NOTE: USE OF A ROTARY BONNET OR ANY OTHER TYPE OF ROTARY MACHINE FOR CLEANING OR DRYING IS NOT RECOMMENDED AND MAY VOID ALL INTERFACE WARRANTIES. This method has low soil removal efficacy and may significantly change the appearance of the fiber over time, including luster and color changes. *ONLY counter rotating brushes are acceptable for this application. Rotary machines move the carpet fibers in one direction. Counter rotating brush machines have multiple heads that agitate the carpet fibers in different directions at once for deeper cleaning without damaging the carpet pile. 7

60 Hot Water Extraction Hot water extraction is an effective method for removing heavy soil and residue from carpeting. The hot water extraction method injects a solution into the carpet. The injected solution suspends the soil and contaminants in the solution for easy removal by the built-in vacuum system. It is important that all vacuum extraction machines are in motion when the solution spray head is activated to prevent flooding the surface. The recommended technique: Prepare the carpet by vacuuming. Start by applying a pre-spray appropriate for carpet using an electric or pump type sprayer. Research by Interface has found that Artemis Bio-Oxygen Carpet Cleaner is an effective product for this step. The pre-spray application should be over the entire carpeted surface, not just the traffic lanes. Agitate the pre-spray with a dual brush counter-rotating low moisture applicator. Allow 15 minutes of dwell time. Operate the floor wand or self-contained extractor by engaging the solution valve or button and pulling or pushing the equipment for approximately three to five feet (or at a comfortable distance). Release the solution valve before reaching the end of your pass to assure that you vacuum up all of the solution. One also may use the Artemis Bio Oxygen Carpet Cleaner in the hot water extractor to thoroughly clean and deodorize the carpet. Cover the same area two or three times both with solution and without solution (suction only) to remove as much soil and moisture from the carpet as possible. Overlap each stroke approximately two inches on the area already cleaned and proceed as described above. Make several additional passes with the solution valve off to remove as much moisture from the area as possible, always being careful not to over wet the carpet. For heavily soiled high-traffic areas this procedure can be repeated until the extracted water is relatively clear. Make sure HVAC system is on and use drying fans (air movers) on wet areas during and after cleaning to allow the carpet to dry completely. Complete the procedure with a thorough vacuuming. NOTE: ALTHOUGH IT IS RECOMMENDED THAT WATER TEMPERATURE RANGE BETWEEN 110 AND 130 F, USING WATER WITH TEMPERATURES ABOVE THAT RANGE WILL NOT CAUSE ANY DAMAGE TO INTERFACE PRODUCTS. LIKEWISE, COLD WATER CAN ALSO BE USED, BUT WARM OR HOT WATER WILL BE MORE EFFECTIVE. NOTE: DRYING TIMES WILL VARY BASED ON INTERNAL AND EXTERNAL ENVIRONMENTAL CONDITIONS. PLAN ON A MINIMUM OF 3 HOURS UNDER NORMAL CONDITIONS. DO NOT ALLOW FOOT TRAFFIC ON THE CARPET UNTIL IT IS DRY. ALLOWING FOOT TRAFFIC BEFORE CARPET IS DRY CAN CAUSE FIBER DAMAGE AND RAPID RE-SOILING. 8

61 Cleaning Solutions Always follow the manufacturer s recommended guidelines for using any cleaning solution. Some carpet cleaning solutions are very harsh and can damage the carpet fiber. It is important to select solutions that meet the basic standards outlined here and to evaluate each product before using it. Interface brand carpets can be maintained using a number of widely recognized and readily available carpet cleaning agents. Interface highly recommends and uses XL North GRAB Fortify LMC for Interim/Low Moisture Cleaning and Artemis Bio-Oxygen for any extraction. We ve listed additional preferences below. The Carpet & Rug Institute also has granted a Seal of Approval for some other carpet cleaners as well. For a list of these certified cleaning solutions see the CRI website at Avoid products with ph levels over 9.5 and products that contain toxic or flammable solvents. Do not use oil-based defoamers of any kind. Detergents designed for use in hot water extraction equipment should not contain an oil-based defoamer and caution should be used with the amount of detergent added. Oil based defoamers have the potential to leave oily residues and adding too much detergent could leave excess detergent on the carpet. Both scenarios will lead to rapid re-soiling and the need for more frequent cleanings. In addition, cleaning solutions containing optical brighteners should not be used. Optical brighteners can adversely affect the coloration of carpet and lead to premature aging or yellowing of the carpet. Cleaning solutions used for Interim and/or Restorative cleaning should be tested for sticky residues that may cause re-soiling. To test a solution, pour a small amount in a clean glass dish. Allow the solution to air dry completely (24 hours minimum). Break up any hard residue on the surface of the glass dish and examine it. If the residue can be characterized as dry powder, dry flakes or dry crystals, the solution is acceptable. If the residue appears oily, greasy, sticky, or in waxy flakes, the solution is not acceptable since it would likely contribute to rapid re-soiling. Spotting solutions should be used as needed and should be flushed out with clean water after the spot has been treated.
