Why
Most cookie sheets are made of aluminum or steel, which can discolor or warp in the high heat and harsh detergents of a dishwasher. Nonstick coatings may also degrade over time. Hand washing preserves the sheet's performance and appearance.
How do you wash Cookie Sheet?
Wash by hand with warm soapy water and a soft sponge. Dry immediately to prevent water spots or rust.
