TPO roof cleaning

I am very pleased with the results after using the Soft Scrub and the Turtle Wax Zip Wash. Using rotary strokes with a hand brush, then rinsing off the roof, things turned remarkably white by the next day.

Well, I can't see my roof, so the aesthetics are of no concern. However, with a clean roof, it is easier to see any problems with with caulk, seams, etc.

But I would NEVER use dish soap, I don't care what manual says its ok. Its more aggressive than any simple car wash solution and will take the wax (and shine) right off the sides of your RV.

The vast majority of car wash products use petroleum distillates

I cannot find any current car wash soap that contains petroleum distillates. Wash n' Wax product may be used to? Dunno...but that's a big statement to make with nothing backing it up.

All I know, is its a well known fact that dish soap removes wax and can dull glossy finishes. Why purposely do that to all 4 sides of your camper? You're just creating more work for yourself.

A clean roof also means fewer black streaks. Much fewer.

My trailer has gutters and drip extensions on the corners. I don't get black streaks.

I clean my roof several times a year and have used Murphy's, simply green,dish liquid and various car wash products using canuba and it all looks the same.
The main thing is to reseal before leaking occurs.

Trailers with rubber roof membrane show black streaks much more not because the roof is dirty but because EPDM chalks whereas TPO does not. I've owned both and would choose TPO hands down over EPDM as a roof membrane.
