How to Get Baked on Food Off a Cookie Sheet
Cookie sheets go through a lot of wear and tear, and baked-on foods will begin to accumulate. Cookie sheets need to be cleaned carefully because abrasive cleaners can scratch the surface. Nonstick cookie sheets can lose their nonstick coating if you do not care for them properly, and if this happens food will stick to them. Instead of throwing your cookie sheet away because of baked-on food, you can salvage it with the right cleaning ingredients and restore it close to its original condition.
