When I moved into my Jersey City apartment my Grandma gave me some of her cookie sheets as a gift. Two years and many batches of cookies later these sheets have seen better days! I decided I should share my trick to get them looking brand new! (almost) Here's how I cleaned the burnt food and residue off the pan.
How To Clean Your Old Cookie Sheet
Step 1. First I made my cleaning mixture that consists of baking soda and hydrogen peroxide. I mix these two together until they are a paste like consistency.
Step 2. Next, I spread the mixture over the entire sheet. Make sure not to use a heavy hand otherwise it will never dry.
Step 3. After letting it dry for about 3 hours I took a sponge and wiped it all off, scrubbing the really dirty parts.
After you give it a good rinse off, it should be looking good as new!
I hope this post finds you before you begin your cookie baking or maybe even after to keep those sheets fresh and clean for years to come! Happy Holidays :)

This is an awesome tip, thank you. I could actually see when baked-on, burned food was lifted-- it was visible staining the top of the peroxide/soda mixture, and in some cases where the spatter was small, could see the entire spot lifted to the top. Much appreciated share!
