Don't bother using kerosene, carb cleaner, mineral spirits, etc. Pick up a few cans of "Mr. Muscle" oven cleaner & a pressure washer to rinse it off with. Resist the urge to use less expensive brands of oven cleaner just to save money. Spray it on let it set up for few minutes & blast it off like mud!! The difference between the other brands & Mr. Muscle is that Mr. Muscle does not require oven heat to work. Most other cleaners require that you heat the oven for best results. You will have to go over a few spots here and there & use the plastic s****ers to loosen it up before blasting it again later. Once it was blasted with the pressure washer it looks great. Things you will need: -6-8 cans of the cleaner(keep the reciept to return uneeded cans) -If you don't already have a pressure washer; rent one from a Sherwin Williams/or rental store. -A few plastic paint s****ers in various widths -Saftey Goggles...not just gl***es, they need to seal to your face. -Gloves, work shirts that cover every inch of you skin!! This stuff will literally EAT YOUR SKIN OFF!!!
