How to Make Your Old Cookie Sheets Look Brand New!

You need to only sprinkle the dirty areas using baking soda. Then, pyroxide should be poured over the top of the baking soda. Next, add another layer of baking soda.

Wipe away the baking soda and hydrogen pyroxide after 2 hours. You will need a minimal amount of energy to wipe it all away with a sponge after your baking soda and hydrogen pyroxide mixture has had time to break down the burned-on oils on your cookie sheet. Finally, rinse well. Your cookie will look as if you just bought it!
