How to remove grease stains from a nonstick C S
Allow the cookie sheet to soak for one to two hours.
Scrub the sheet gently with a very soft scrubbing sponge made for non stick pans, or a nylon sock. The baking soda and vinegar will create a gentle scouring paste. This should remove any left over residue.

The coating on nonstick bakeware and cookware can be scratched in the dishwasher. Wash your nonstick items by hand.
