Review on 🚫 Bio-Kleen M00509 Black Streak Remover - 128 fl oz. by Jason Sisawang

review. I used a full gallon to flush my entire camper with this product as it was stored in a shady wooded area with no cover over the winter. It was a huge black stripe with lichen growing on it. At first I washed everything I could with regular soap and water, then this product was like a black streak eraser. However, be sure to check your finishes and be on the lookout for any inferior decals you may have that you don't want to ruin. And when you're told to start at the bottom and work your way up, listen. I don't know if that's the reason, but if you start from the top you get white streaks from the product running into the dirty area. Then you need to lubricate the elbow a little in the area below to even out the streaks. I had to do a few passes in the hardest hit areas but that took care of everything.
