Hey do you guy's know of any heavy duty degreaser that wont F#%k up my paint or my wheels. I work at a coal mine and I thought it was just coal mud on my fender wells but they treat the roads with some gunk and it will hardly wash off I used the car wash degreaser twice and washed the sh#t out of it. I got quite a bit of it but it is really hard to get off. Please help( thanks ).
