The black streak cleaner was absolutely amazing. I have tried many products and have been very disappointed but this is wonderful. I have told all of my friends about it.

The product was great! Actually removed black streaks without scrubbing and left the surface looking like new.

This stuff is awesome. I have tried several products to get the black streaks off my white horse trailer. The ones that would take it off you had to rub and rub and rub. Biokleen is so much easier. You just spray it on your rag and start wiping. I found that the more that I had on my rag the better it worked. Bear in mind my trailer was very badly streaked. I did not wear my arm out using this product. I did have to wash the trailer with soap and water after to remove the film but it washed off easily. My trailer was so streaked to the point it looked gray and now it looks new.

this is the best black streak remover EVER!!!! it cleans the rv so nicely.

I recently bought a gallon of the Black Streak remover to clean my RV. The product works fantastic, I was very pleased. I have used other black streak remover products with no results, remained dirty after alot of scrubbing. The Bio Kleen not only cleaned the black streaks but took off other years of grime that didn\'t come off. And it took it off with much less effort.



Its a great product, I am telling all my RV friends about it.



Thanks for making it,



Randy
