Camco Camper/RV Pro-Strength Black Streak Remover, 32oz (41008)

I used this on a stubborn black streak on the seam of my Casita Spirit Deluxe (fiberglass camper). I've been trying to get rid of this black streak for a long time. My first attempt was with following the directions on the bottle, wet and leave spray on for 30 seconds and scrubbed with a plastic bristle brush. That didn't cut it, no different from anything else I tried. On my 2nd attempt, I sprayed it straight onto the black streak without water first. I let it sit a while and lightly scrubbed with a wire brush. I could see the streaks were dissolving and hit it again and same process. The streaks are gone!!!

Works great and pretty quickly. Great value for the price.

I have not tried this on black streaks yet. However, we used it on our ATV before applying the new registration stickers and it worked great. We own a camp trailer and I am sure we can use it on that also. I would hope it can work on black streaks on my floor too. I will be trying it out on many more things and can update the review when I have used it on more things.

They couldn't have picked a better name for this product because it truly does remove black streaks especially from campers and RV trailers. For many years I owned an RV business and sold and serviced R v's and campers and we have tried many products to remove black streaks from the outside , this is the only thing we found that truly works.

If you own a camper, you know just how annoying those black streaks are from all those seals! Our camper is coverless and when it rains here in Florida, the camper always has streaking from all the seals. We have been using a competitor product; however, it just does not do a particularly good job of getting rid of the streaking. A friend told us about Camco's Black Streak Remover, so we tried it out. He told us that a bottle and a microfiber cloth is all we need, and that we can use it whether we are at a campground that doesn't allow washing, boondocking with no water to spare or at the storage unit with no water access. So, we gave it a go. We have found taking a small bottle of this with the solution allows us to remove the streaks that may accumulate for small jobs and using the quart bottle with the cloth for larger jobs. The Camco Black Streak Remover is the latest product to join our maintenance bucket! This product swiped those black streaks right away! Removing them from the camper before they sit for a long time is key to keeping the camper looking it is best. Once they sit on for too long, it is difficult to get them off as we found out after purchasing a used Class C years ago.

I buy and resell items, so I deal with a lot of stains. My utility sink takes a beating. I clean everything from rubber sole shoes, outdoor products, wheels, etc. I have tried bleach, comet, magic erasers, etc. to clean my sink, but nothing takes care of the staining. So I decided to give the Black Streak Remover a try. See the pics for yourself, it is the cleanest I have seen it. The smell doesn't "knock you over", it's clean/refreshing. I followed the directions as instructed leaving the product for 30-60 seconds. The spray did a nice job.

I used this on the black streaks and built-up mildew on my vinyl siding. It was very easy to use and worked quickly. I had to do some light scrubbing with a green scour pad. It did not remove the black streaks completely, but they are much lighter and not as noticeable. Bleach didn't work on these stains.

I used this on black marks on my vinyl siding and front door. It did a decent job at getting the black marks off as well as the green residue off my vinyl siding. It is very easy to use. Spray it on, then if needed use a scrub brush and then spray off with water. I also tried it on the grey and black residue that gets on the railing and sides of our quick set pool and it done a fair job. I would recommend to anyone who needs to remove black marks or streaks from something that can be sprayed with water.

Gets some black streaks off, but not most. Used on a 2025 after one season and still a lot of black streaks. Would not buy again.

The service was fast but I have a sign across my front deck that says deliver all things to the back door since we don't use the front door and there isn't even a driveway to the front door. The person delivery these had to go under the hanging sign to place them on the front deck. People can't read anymore.
