Why
The harsh detergents and high heat in dishwashers cause aluminum to oxidize and discolor, leading to a dull, grayish appearance. Additionally, the caustic environment can pit the surface and degrade any non-stick coating if present.
How do you wash Aluminum Cookie Sheet?
Hand wash with mild dish soap and a soft sponge or cloth. Dry immediately to prevent water spots and oxidation.
