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.

High quality

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.

very fast shipping, thanks!

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.

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.

I haven't had a chance to use this on the camper yet but thought I would try it on the black mold in our shower. It didn't touch it. Left it longer than recommended. Will update when I try it on our camper next week. Don't hold out good hopes for this product. Have used similar products from them that don't work.

I dont know what contributed to my results but this chemical burned the paint off my camper to bare metal. This chemical is very harsh. I would never use it or recommend it.
