Cleaning those Black Streaks

Washed the outside of the coach yesterday and had a hell of a time with the black streaks. Tried that "Black Streak Remover" sold in stores and it did not seem to work so well. Some suggested some C.L.R.....maybe next time.

What did work great was a "Mr Clean Magic Eraser" I do not work for the I found it to work very fast however not looking forward to washing the whole unit with one. Good thing there are only a few black streaks to contend with..!

Sorry to hear you used that Black Streak remover & even sorrier to hear you would used CLR.
Using that Black Streak remover is the worst thing you can do.
It strips the finish allowing that area to oxidize quicker. You will find that area getting dirty quicker/sooner than the rest of the rig.
We learned that three RVs ago.

The best way to remove the black streaks is to prevent them to begin with.
The best way to prevent streaks is to keep the roof clean & you will not have black streaks on the sides.

I wouldn’t use CLR either. Anything that removes rust & other stains will ruin the finish.

I use Thetford rubber roof cleaner twice a year & have never had a streak of any kind on the last two rigs.

I would be careful using magic erasers, I read on a forum and then research that magic erasers are very light sand paper like material that sands the spots off. I donít think it would be good for the finish of your RV.

Nufinish automotive polish works well at removing stains.
Better yet never get another rubber roof trailer(that's what I have realized)

X2 on WD 40 EXCEPT if the stains have been baked on for months or years. Then good luck! Keeping the rubber roof clean as mentioned is the easiest way to keep the stains off the sides I've found.

My Georgetown is listed as having a laminated fiberglass roof, not rubber. I get the black streaks too.

What cleaner do people use that have this kind of roof material?

I cleaned my roof and still ended up with black streaks. Good thing I have the gutters. I only get them on the front and back. But nice to hear about not using the black streak remover because that's what I was going to buy.

X2 on Awesome Orange. Have used it a lot and great results. Had an older Aljo with metal side. Was the only thing that worked after trying everything else.
