I have a class A with a fiberglass roof. I park it along a tree line in the summer & inside in the winter The roof is black on about 25% of it. I got up there today with a bucket of oxyclean mixed ...
I'm just about done. Where is the mold going? When I spray my 50% bleach on it turns kinda brown & then it turns white. Nice & clean!!!!! Don't wear a nice shirt Don't do it when there's too much wind.
