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

Last year I bought black street remover from Walmart. It did work, but it took an awful lot of elbow greece and several applications and a lot if work to get the black streaks off. I think I lost about 10 pounds. Now to be fair, I did put a ceramic coating on the camper about 2 years ago. However, it was not the expensive kind, just the spray bottle type. It's supposed to only last 6 months so I'm pretty sure that that was not a factor. I sprayed a section on one side of the camper which was heavily streaked. I sprayed it on a dry surface as recommended. It said wait for 2 or 3 minutes, but being a little bit impatient, I tried to wipe it to see if it would work. It wiped the black streaks off so easy it was ridiculous. After wiping off, a section, the microfibre cloth was quite wet. I used the soaked cloth on on another area that I had not sprayed and as soon as I wiped the black streaks just wiped right off. I immediately ordered a second bottle of it as I did not want to run out this weekend when I clean the camper. It worked great for me.

This works great at removing streaks.

I've had an RV since 1998 its fiberglass. Black streaks are always an issue obviously on lighter colors. The stuff 303 works. If you don't wash your vehicle regularly and you expect this to work after years of neglect well good luck with that. But if you maintain your vehicles this will definitely get out the black streaks. Some water stains can't be taken out except for maybe with a buffer. But this does what it's intended to do. And don't forget to rinse it off after. Very impressed, thought I'd take a shot at it .Ive have black streaks in some spots for years that I've almost gotten used to now it looks like a brand new vehicle. Any negative reviews don't make any sense to me.

I love 303 Aerospace protectant, I put it on everything especially my old Honda Element with lots of body plastic panels. So I was relying on 303 to come through in this too. It is OK. The dark streaks on the side of our small RV travel trailer are very annoying. The dark black Butyl sealant use all over it constantly leaves dark drips on the sides. This cleaner does help but works just as well as may other household cleaners including some home concoctions from white vinegar and dish soap. I will use this up and perhaps try another brand in the future to compare them. But I do trust 303 products and will definitely slather some 303 protectant on after I use the cleaner.

This stuff saved my Scamp!! It removed the black stuff that pressure washing had left behind! I really thought the black stuff was permanent on my 13 year old Scamp. So worth getting this!!!
