Before you buy a pricey stainless steel cleaner to keep your appliances looking new, try this to restore the shine and luster: mix one tablespoon of cream of tartar with just enough water to make a milky-like solution. Rub this liquid, with a sponge, onto your stainless steel refrigerator, stove, dishwasher, etc, then wipe off with a damp cloth. The cream of tartar is a gentle abrasive that removes grease and grime just as well as the expensive store-bought versions.
