1. Baked-on cookie sheets can often be tough to clean, especially if the sheet was not properly greased to begin with. However, there are several tricks to make the cleaning easier and to make baking cookies that much sweeter.
2. Place the cookie sheet in the sink, and turn on the hot water to soak the sheet in hot, soapy water.
3. Return to the sheet 10 minutes later, when any particles stuck to the cookie sheet have been softened. Use your sponge to remove them from the cookie sheet.
4. Then use the soft side of the sponge to give it a good soaping; this will remove any oil on the surface. Rinse, and your baked-on cookie sheet is ready to be baked on again.
Thanks and Regards
