They say on EPDM roofing stay away from detergents that contain petroleum solvent or citrus. In looking for an acceptable, cheap and easy substitute.. the consensus is Dawn dishwashing detergent. Works great on the roofs, get on your hands and knees with a scrub brush and have at it. Rinse thoroughly. After it dries a day or so, go up and look carefully at all the caulk around anything that comes up through the roof, vents, roof caps etc. If you have to, Dicor self leveling sealant. You don't have to take off the old stuff but, do wipe the area down with a rag and alcohol first. BTW Nu-Finish car wax works nice. Takes off the black marks and you won't wear your arms out
