Cleaning Brite-Ply EPDM Roof?

Oxyclean? Dawn? Bleach? Spic-n-Span? Thetford Premium Rubber Roof Cleaner & Conditioner?

The roof was in a coastal wooded area, not directly under trees.

It is the white EPDM and feels a little "slimey" with a little green tint, especially on the edges.

No cuts, holes, or leaks.

I'm thinking maybe algae? A little mildew?

I've read a wide range of opinions about cleaning EPDM/Rubber roofs. Generally "leave it alone but keep it clean, unless you have to"

I am thinking I need to kill off any of the growth, but prefer not to hard scrub our 12 yr old roof. I plan to reseal and possibly replace a vent or two, but not much else since there aren't any active leaks that we've found.

We were considering oxyclean or bleach to kill the growth, but will that be any problem for the fiberglass sides or the Dicor sealant or plastic roof parts, like vent cover, fridge vent cover, etc?

It's on our 2005 Keystone Cougar 304BHS Bumper Pull.

Opinions and ideas? Favorite products?

I recommend you do the same as the commercial roof folks .... NOTHING ... attempting to clean will IMO only shorten the overall life of the roof due to abrasion and removing the naturally occurring residue that forms over time.
