Awning Mold or black streaks

X2 on magic eraser!

Clorox Clean Up for mold.

It wont stop it from coming back but "Tilex Mold and Mildew" Link Does an incredible job of removing the black mold.
I didn't want to spend anytime scrubbing mine this year so I just brought the bottle along. I mixed the entire bottle with a gallon of water in a garden sprayer and soaked the awning down at the CG. After leaving it wound up and soaking for three hours, I extended the awning and was shocked. It was 99% spotless. Only a few little spots at the outside edge that dried out wern't clean.

With our trailers I'd extend the awning and get on the roof with a bucket of water with bleach in it. Brushed down the awning with the solution and then rolled it up for about 1/2 hr. Open it back up scrub with a soft brush and dawn dish soap water. rinse well.

Others on this forum have sung the praises of Mr Clean Magic Eraser for getting rid of the awning streaks.

That is what I am going to try next.

Fought that for years. was good until I put it up after camping in the rain and left it for one week. Was Never the same.

I used spray and cleaners and it got about 80 percent clean and even scrubbed it.

New camper has a awning cover and it is awesome.
