Mold and mildew on rv roof

[Steelworker]

Our rv has a some old dried mold or mossy growth that has not been removed in a a couple of seasons i suspect. What i was wondering does anyone know what i could use to safely remove this growth?The roof is made of rubber .

I would get some Hose'n Go Moss Out! for Roofs, follow directions. It attaches to the garden hose and spray it on. After waiting the appropriate time gently pressure wash the roof or scrub it with Dawn and a soft brush, hose it off. Now is a good time to inspect the roof and repair failing seals.

Wet and Forget. It won't be instantly clean but give it some time. No scrubbing.
Follow the mixing directions and use a garden type pump up sprayer. Probably need 1-2 gallons in the sprayer.
