Sometimes it just takes "manning up" and use what's needed to get the job done and quit worrying about it. Nice job. When we had our '99 Fleetwood Bounder 34V with the F-53 Chassis, that rubber roof was cleaned with a good brush and soap and water, about once every two months. It was done that often 'cause it was stored outside and, in the area we lived in, would get considerably dirtier than if under any garage or cover.
It never hurt that roof. There's so many folks think that stuff is tissue paper and if you breath on it, you'll damage it. Aint happening. The SUN is it's worst enemy, by far. Keeping it clean helps keep contaminates, acid rain and other air born crap off it.
