I sprayed Pam baking spray all over my non-stick muffin pan one day. I had been using it, but only spraying the holes the batter goes into. This day, I knew the muffins would rise up and spread out a bit, which they did. The areas with the spray, but no batter, came out of the oven a sticky, mess that would not soak off or come off in the dishwasher. No amount of elbow grease was working. Gene, being the "can do" guy has had it in his workshop for about a week, (I had asked him to toss it) trying to clean it up. He has been using degreaser for cleaning cleaning garage floors, car engines, etc. with a power washer! Ugh. So my question is, should I even use this for cooking once he finishes his job? My gut is telling me to toss it.
