After it stops raining here in the NE, I will be cleaning the rubber roof on my TT. I've done some research and believe the best option is to use a medium bristle brush and clean with a solution of Murphy's Oil Soap. Then when dry, apply Airspace 303 Protectant. As always, I will appreciate what other more experienced RV's do to clean and protect their rubber roof.
Same here, IMO scrubbing and rubbing only shortens it's eventual life. The only time I would do anything is if and when grass and weeds started growing from the dirt build up:W

Here is a photo of the rubber roof on my TT, discolored from weathering. It at least warrants cleaning - just hosing down is not an option. I'm still not sure if/what UV product to use afterwards.
I was given CamCo roof cleaner available at Walmart. It sat on the shelf for a long time, but then I went to clean the roof and didn't have my usual Spic & Span so I used it. Was not enthused while cleaning, but the rinse water was brownish. But when it dried, boy what a difference - very white and bright. Here is a picture I used for selling it taken after cleaning it and laying down caulk. I use a soft brush on a threaded pole.
Experience without good judgment is worthless; good judgment without experience is still good judgment!

Talked to Dicor (who makes most of the rubber roofs) at a Good Sam rally a few years ago. They recommended using their cleaner and protectant saying that the more expensive treatments are not needed.
Thatโs not what Winnebago recommends. โThis rubber roof material does not require coatings to protect the surface from ultraviolet light or ozone.โ
