lwhen you power wash the under-body, do you use any decreasing solvents through the power washer or are you washing off loose grime then hand cleaning with the de-greaser?
Im not trying to cur corners, but if i could feed the de-greaser through the PW that would be good.
Have you ever tried to use a de-greaser mix of some type in your foam lance on the PW?
Not to hi-jack the OP but I use Oil Eater, I spray heavy stuff on the undercarriage straight but put a diluted mix in my pressure washer to break up grime. I just wouldn't use it on paint... At all
