BiokleenM00505 Black Streak Remover, 16-Ounce

I have used many products saying it will take off the black streaks on my camper, which non of them even worked. I finally found something that works great. I found this product by watching You Tube with someone using it , and thought I would try it. I bought the smaller bottle thinking if it didn't work, then I wouldn't have waisted my money on such a big jug, but now I will buy the bigger one when needed.

I had black streaks on my white pontoon boat aluminum walls. I had tried several other products and scrubbers and lots of elbow grease to no avail. This product worked instantly! Just spray and wipe. No damage to the finish. I’ve been told these black streaks are common for Lake Norman due to pollution from local power plant.

I don’t regularly write reviews. I only write for products that I think deserve praise or deserve to be called out as junk. This product is the former. I used to use straight bleach to clean the black streaks from my fifth wheel. My fifth wheel is white and black streaks show up and make it look horrible. It was a constant battle every spring. Bleach would work OK. It would take 90% of the streak off and then you had to scrub and scrub and scrub to get the rest of it off. No word of a lie this product removes black streaks 100% in a single shot with a single wipe. I was amazed. I couldn’t believe it. The only thing I did extra was spray streaks and let the product sit for about two minutes before I wiped it off. It worked amazing. I don’t know what else to say. I was shocked at how this product worked. Only problem I had was the super high price for the 16 ounce bottle! I did a little research and the gallon jug is only 25 bucks. About 1/4 the price per once compared to the spray bottle. Do yourself a favor buy the gallon, buy an empty spray bottle go to town. I cannot say enough about how this product works absolutely amazing. I have no connections with this product and I’ve never heard of it before I ordered it prime three days ago.

I've only tried a small spot on my white travel trailer covered with black streaks and it did work with lots of scrubbing with a magic eraser. I was hoping to spray and wipe but maybe that was wishful thinking!

Worked well, as I was in an RV campground and it rained night before. Also add in a shaded area helps the process. Black run line areas needs a bit of heavy elbow grease, overall works well. Cleans up very well as long as you stay on top of it quarterly depending on your travel areas

As advertised! I have a pontoon boat that has had black streaks down the side panels for a couple of years. Nothing I could do or find (without ruining the paint or stickers) would work to clean up. Sprayed product on and streaks wiped right off. Was amazed at how great of a job this product did. Wish I would have discovered it two years ago.

You have to be careful with this product, I ended diluting with water becasue is very strong and in my case the product removed the paint from my camper.

Used it on a few streaks before covering for the winter. Seemed to work pretty good. Would have given five stars if I had more time to try it. Will update in the spring.

Product came empty and damaged.
