I bought and used 5 cans of it from the 99-cent store to clean my entire front and rear end of the 52. Worked great. Laid painter's plastic under the truck before beginning and let it melt off. Tossed the whole thing when finished.
Nothing frustrates me more than going to a car wash and having to deal with the mess that some guy left blasting grease all over the place.....
Good Luck
Did you spray with water? I need a similar solution because the undercarriage is a mess and I can't move the truck out of the garage right now. I was wondering if the solvent (be it oven cleaner or something else) would eat the plastic. My thought was to line a blue kiddie pool with some sort of plastic sheet, and use as little water as possible.
