Cleaning black streaks

An RV tech told me that it is butyl caulk (or tape) that causes the black streaks.

Gotta be careful with Awesome. I used it on an older aluminum sided trailer that was also oxidized and if you let Awesome sit on the paint too long, it will actually dissolve the paint.

I know awesome does a good job removing wax , works good on soap scum on a bath tub too

"Seconds" is how long it should be on the surface ;)

FYI. It did take Blue (only blue) off the swoops in our decals. Not enough to affect the decal, but enough to wipe onto the white fiberglass. Gotta be careful with stuff like that ;)

Anyone out here have a tip for removing the black streaks that all campers seem to get after sitting for a while?

I've tried:

Magic Erasers
Simple Green
Soap
Citrus cleaner

We use Awesome from the dollar store, puts to shame all the so called specialty products for black streaks.

I just ran into the BEST way!!! DH was cleaning with official Black Streak cleaner. I got out my Bar Keepers Friend bottles and handed it to him to just try. It was amazing!!! No scrubbing!! He wiped it on, and wiped the black streaks off!!!

What kind of Bar Keepers, Spray & Foam, All Purpose Spray, or one of the soft cleanser? I've only used the dry cleanser.

I have a white truck that sits outside. After a while it will have black streaks on it. No butyl tape, caulking or rubber roof. It must be the dirt in the air that we breathe.

My RainKap system stops 100% of black streaks from roof runoff. It also prevents/reduces greatly any black streaks from things like windows or wall fixtures even after 6 to 8 months between normal washings.

I followed Larry's lead this year. Will be interesting to see how many less streaks will be there when I pull the trailer out this spring. I usually use Simple Green, which does require a little elbow grease but does clean the streaks off. Maybe I'll try one of the other products mentioned in this thread. I do know that magic erasers don't touch the streaks on my trailer.

Another vote for Totally Awesome! Works great for us on our 1996 Coachmen. There may be better stuff out there, but it ain't a dollar a bottle, and probably doesn't work much better.
