When cleaning the exterior, always rub with the “grain” ofthe stainless steel to avoid marring the finish. Do not use an abrasivecleaner because it will scratch the stainless steel and can damage thebreaker strips and gaskets.Stainless Steel Care and CleaningTo prevent discoloration of rust on stainless steel several importantsteps need to be taken. First, we need to understand the propertiesof stainless steel. Stainless steel contains 70- 80% iron, which willrust. It also contains 12-30% chromium, which forms an invisiblepassive film over the steels surface, which acts as a shield againstcorrosion. As long as the protective layer is intact, the metal is stillstainless. If the film is broken or contaminated, outside elementscan begin to breakdown the steel and begin to form discoloration ofrust. Proper cleaning of stainless steel requires soft cloths or plasticscouring pads.NEVER USE STEEL PADS, WIRE BRUSHES OR SCRAPERS!Cleaning solutions need to be alkaline based or non-chloride cleaners.Any cleaner containing chlorides will damage the protective film ofthe stainless steel. Chlorides are also commonly found in hard water,salts, and household and industrial cleaners. If cleaners containingchlorides are used be sure to rinse repeatedly and dry thoroughly.Routine cleaning of stainless steel can be done with soap and water.Extreme stains or grease should be cleaned with a non-abrasivecleaner and plastic scrub pad. Always rub with the grain of thesteel. There are stainless steel cleaners available which can restoreand preserve the finish of the steels protective layer. Early signs ofstainless steel breakdown are small pits and cracks. If this has begun,clean thoroughly and start to apply stainless steel cleaners in attemptto restore the passivity of the steel.Never use an acid based cleaning solution! Many foodproducts have an acidic content, which can deterioratethe finish. Be sure to clean the stainless steel surfacesof ALL food products. Common items include, tomatoes,peppers and other vegetables.tab on top ofblue safety clipCAUTIONCAUTION
