I would like very much to see any reference to a manufacturer of EPDM or TPO that recommends using gasoline to clean their roofing material.

I would like to see ANY reference to using a highly flammable gasoline to doing any type work on an RV. BTW, NOBODY uses Gasoline to clean a roof EPDM or otherwise. Doug

Dishwashing soap, then alcohol.

You can use aceton, but it's stinky, will give you a headache, and in a hot weather it evaporates so quickly that doesn't do anything.

Rub it thoroughly on every stage - with soapy water and with alcohol. The goal is to remove whitish powdery residue of oxidized paint. The paint is deteriorating with time, turns into a powder, so you need to remove it. The surface should look smoother and shinier than before. Don't overdo it, stop when you start seeing black spiderweb cracks - this is a black rubber shows under the white paint.

And I think it's EPDM

Routine cleaning ... Bucket, Mop, Water, Spic & Span.. For the 2nd (Rinse) pass. Hose and sprayer

For pre-eternabond application.. Start with above, Optional: Let dry.

Then using a clean cloth and Alcohol (not the drinking kind) Let dry

Then apply Eternabond.. Let stick

Then touch up with spic & span again to make sure all the alcohol is history.

(Wait a day before that)

Denatured alcohol, mineral spirits, acetone. Do not use anything with petrolium distillates or citric acid.

Ajax and a scrub brush is what my manual says to use and it works great. Craig

SOAP AND WATER, followed by lots of water. Rubbing alcohol is the only other solvent safe for the EDPM rubber. Anything with petroleum distillates in it will damage the rubber.
