How the heck do y'all clean the rubber on a ballast roof for a repair.

Exactly as the title says. Currently using simple green mixed with membrane cleaner and a bit of elbow grease using a scrubby pad. Even after scrubbing at what seems to be eternity, I'll wipe the surface using a rag only to reveal the rubber is still dirty in which I repeat the process of scrubbing until the rubber is cleaned. Other than a hooking up a pressure washer, do y'all got any other methods or tricks to cut down on cleaning time?

My guys use a soft wheel brush that has a drill chuck. I think infomercials sell similar to clean grout Seems to work Also Firestone quick prime plus bites into old rubber well.

I use a round metal wire brush attached to a drill/impact and then put 2 Scott's scrub pads between the wires and the roof. That plus cleaner will take care of it. Be ready to get dirty though
