The best way to clean a stainless steel oven is to use a soft cloth and stainless steel cleaner or other cleaning solution. Abrasive cloths, sponges or cleaners should not be used to clean stainless steel appliances.
Smudges, fingerprints, streaks and spots can be cleaned from stainless steel with a spray cleaner intended for use on stainless steel. An individual can dampen the soft cloth with a little water, spray the stainless steel cleaner on the cloth, and wipe the oven along the grain of the stainless steel. Long swipes should be used instead of circular motions. The surface should then be dried and buffed with a clean soft cloth.
There are other cleaning solution options, if an individual does not have stainless steel cleaner, such as a dish detergent solution. An individual can combine one teaspoon dish detergent with one quart hot tap water and clean the oven with it in the same way as using stainless steel cleaner. The dish detergent solution should be rinsed off with clean hot water before drying with the clean cloth.
Other cleaners that may be helpful include a paste of baking soda and water, stainless steel cleaning wipes or mineral oil for buffing away streaks. Liquid cleaners that contain oxalic acid can help clean spots with tarnish, rust or other small blemishes. For best results, any grease or smudges should be cleaned up immediately.
Stainless steel should not be cleaned with cleaners, such as steel wool, ammonia, bleach, wax or acids.
