Re:Cleaning cooking spray residue from pans?
It sometimes works if you make a paste out of baking soda and water. Spread it over the sticky crap and let it sit about a half hour. Then wash in hot soapy water with a Brillo pad (assuming it's not a nonstick pan).
Once you get it removed, the best thing is to catch it before it cools and wash it in hot soapy water.
