easy way to clean cookie sheets
Here is a good tip From a teacher in high school teaching Foods, when baking muffins and you don't have enough to fill the rest of the tin, fill them 2/3 the way with water and continue baking. They will come out looking brand new, I thought if that worked then I could fill the cookie sheets with warm water and bake them in the oven @ 350 for 20 mins they would come clean, Well I did try it and what a pleasant surprise my old cookie sheets now look brand new.
