Just starting out in the pressure washing field. Purchased a newer Hot water machine 8gpm,3,000 psi, 20hp honda and Beckett burner. It cleans the old dirt and grime from concrete but the oil stains in concrete just dont seem to come up. Any suggestions, I haven't purchased any chemicals and dont want to waste my money trying 10 diffrent products. Any comments will help.
