303 ProductsBlack Streak Remover - Removes Black Streaks and Dirt, Provides A Clean, Streak-Free Finish on RVs, Campers, Pop-Ups, Motorhomes, and Boats, 32oz (30243)

For the naysayers out there....This product is designed to break down the black streaks. You have to wash your vehicle after wiping away. This product is not a wash and wax. Your bad reviews almost caused me to buy something else. I'm glad I didn't listen to you!

Did not remove ANY of the black streaks on my RV

The media could not be loaded.  Bought a bottle of this 303 Black Streak remover because I’ve been using their protectant spray for several years, and I’m quite happy with it. They’ve been expanding their product line and I saw this and thought I would give it a try. It didn’t disappoint.This is the 10th summer for this camper. It seems the black streaks are getting harder and harder to remove after every passing year. I clean the roof and wax the trailer. Everything I can think of to keep the streaks at bay. I wanted a good black streak remover. I’ve never had a need for this type of product until late last year, so when it came time to get the camper out of storage, I went at it full force.Like I said, I have nothing to compare it to, but this stuff is amazing. Spray the affected areas and let it sit a few minutes. Wipe off. You might have to rub a little harder in spots but it’s nothing major. No different than removing paste wax with a microfiber towel. I followed it up with 303 RV Wash and Sealant.I don’t think the camper ever look so good. So clean.This will definitely be a tool I keep in my arsenol.

Works somewhat reduces visibility of the black streaks

Have been looking for something to get these aggravating blackstreaks off and this does the job. Easy application and removal. Will definitely buy again!

I'm not a guy to write a review but this product is worth a few minutes of my time. We recently a new to our family family (2018 Keystone Hideout 28BHS). After washing it, I was disappointed with the black streaks left under the windows, cargo door holders, and all the other black things that leak down the sidewalls. Purchased this stuff knowing 303 products are good and man did it not disappoint. For me - i sprayed it on the affected areas and it wiped right off!

This is the ONLY thing that will take off black spots and streaks on vinyl boat seats.The black is caused by acid rain btw!!Husband is extremely satisfied and shares his enthusiasm with the rest of our friends who have the same problem.Thanks for another great product!PS Be SURE you finish with the protectorant, insurance of all your work to clean!!!

I was hoping it would make it easier to remove the black streaks on our RV. It did not. It did well cleaning other areas of the fiber glass.
