Here's an odd thought I just had. Has anyone ever tried that foamy sray on oven cleaner stuff. You know, spray it on overnight, hose it off in the morning. I know it's a great grease and crud cutter and doesn't strip paint off the oven. I'd prbably cover hoses and belts, have no idea what it would do to rubber. I might try it next time I degrease, unless someone has had a bad experience with it.
