Question: are baking sheets dishwasher safe?
Answer: Stick to hand-washing. “Harsh dishwasher detergents can mar and discolor nonstick or natural finishes,” Norsten says. In most cases, some mild dish soap, warm water, and maybe a light pass with a no-scratch scrubbie will do the trick, no matter what type of pan it is (nonstick-coated, aluminum, or aluminized steel).
