Well, im my rebuild of my 444, I am uncovering a TON of crud. Oil, sludge, grass, etc. What kind of cleaner do you all use to clean the real nasty stuff? Not to concerend about the paint. What is there is already pretty fadded, or chipped, just want to get the crud out. I don't have a pressure washer, so what ever has to work with a hose. Any tips for me??
