Stainless steel appliances are quite difficult to stain, however not impossible. If you have a stainless steel appliance and are worried about it rusting, there are some precautions you can take to make sure that it never does.
The first think to know is that although stainless steel is still steel and is capable of rusting, it has been treated and contains chromium. When chromium comes into contact with the air, it generates a shield called chromium oxide that is resistant to rust and stain. This chromium oxide shield is an important component to any stainless steel appliance, if it becomes damaged rusting will take place in the area of the damage. With proper care and regular cleaning, your chromium oxide layer will remain in good shape and do its job of protecting and maintaining your stainless steel composition.
Preventative actions for quality assurance include proper use of cleaners on your stainless steel appliances. Certain cleaners that contain chlorides such as; iodine, chlorine, fluorine and bromine should never be used on stainless steel, nor should alcohol, ammonia or mineral spirits. For best results, you should only use stainless steel cleaners, such as this Whirlpool Stainless Steel Cleaner.
While only using stainless steel cleaner to clean your appliances is important to prevent such stain and rust, it is equally important to take action to make sure water and other liquid is not in direct contact with appliances. Never hang damp or wet dishtowels from your dishwasher, stove or refrigerator, this can lead to rusting caused by moisture from the dishtowel. Also note, when you do clean an appliance with the stainless steel cleaner be certain to never use rough towels or sponges to wipe it down, this will scratch.
