How to Clean Your Dingy Baking Sheets So They Look Like New Again

Sprinkle a layer of baking soda over your baking sheet, then follow it up with a layer of salt. Put white vinegar in a spray bottle, then spritz a layer of the liquid over your pan.

From here, you can either start scrubbing with a sponge or, to make your work a little easier, soak the pan in hot water for 30 to 60 minutes before going in with elbow grease. Once you’ve worked off any stains and caked-on food, wash the pan with regular soap and water.

If your aluminized steel pans have seen better days, you can use baking soda and hydrogen peroxide to get them shining again:

Sprinkle a layer of baking soda onto your sheet, then pour on a generous amount of hydrogen peroxide. If needed, add more baking soda until it resembles a paste.

The key here is to give the mixture time to work its magic, so you have to be patient. Let the pan sit for two or three hours, then wipe it away with a cloth. If needed, you can use a coarse sponge to scrub at stubborn spots. Wash the pan with soap and water before using it again.

Mix together water and baking soda into a paste-like consistency. Cover your cookie sheet in the paste, and let it sit for 30 minutes. You can then take a non-abrasive sponge and scrub at the residue.
