How to clean your cookie sheets--
Kitchen "Miracle" Cleaner!
You put about 1/4 cup of baking soda in a small glass bowl and squirt in hydrogen peroxide until it makes a nice paste. Then you rub it on the offending dirt/stain/grease...whatever!
You can usually just use your fingers...but you can also use a small sponge as well.
