30 To clean products made of stainless steel we recommend using cleaning solution dedicated particularly to stainless steel material. It preserves the steel surface from permanent stains and at the same time retains aesthetic appearance of the product. INOX products are manufactured with stainless steel. When used in standard laboratory conditions they do not rust. However it is possible that stains (which may look like rust) form on the steel surface (e.g. due to the kind of samples that are incubated in the chamber). In such case we recommend using cleaning solution (to clean the stains) which is dedicated to this particular application, e.g. Pelox. When cleaning stainless steel product with dedicated cleaning solution, one should pay attention to the suggestions and recommendations given in the user manual (or in the safety data sheet) of the cleaning solution Housing cleaning 1. The housing of the device should be cleaned at least once a week, depending on the working conditions. 2. The housing and door should be cleaned with caution using a soft cloth dampened with water. 3. Only mild cleaning products should be used to clean the device. 4. Electrical parts should not get in contact with water or detergent Interior cleaning 1. The chamber should be emptied of any samples before cleaning. 2. Open the door of the device and wait till the chamber has cooled down, take out the shelves and start cleaning the device, 3. Only water or water with mild detergent should be used Having finished cleaning, you should allow the device to dry fully and fit all parts removed before cleaning. During cleaning you should make sure not to damage the temperature sensor built in on the top of the chamber. In drying oven could happened the internal bottom metal part becomes discoloured.
