Stainless steel appliances need to be cleaned often to maintain their shiny luster. Fingerprints can be the most troublesome marks to remove from the surface of smooth-polished or bright-finish stainless steel, such as an oven, microwave or a refrigerator.
Fortunately, fingerprints can be easily removed with a glass cleaner like Windex. Simply apply the cleaner with a soft rag and follow with a thorough warm water rinse. Fingerprints may be annoying, but you can relax knowing that they don't impact the corrosion resistant properties of stainless steel.
For especially stubborn fingerprints or surfaces, use a paste of sodium carbonate (soda ash) applied with a soft cloth. Be sure to rinse with warm water.
