The product downer live up to the advertised claim
Washed a side by side section of my 2022 rv with poli prep and simple green. The comparison was tragic. Simple green definitely is a superior product. Don't waste your money.

Great cleaner for tough stains on fiberglass
This cleaner was recommended by a fellow boater. I was having difficulty cleaning some black streaks on the hull, and dark stains on the water line. After trying several excellent cleansers that have never failed me, I decided to give this one a try. It cleaned up the stains when used as directed and did not damage the finish on the gelcoat.
A good cleaner to have in your arsenal!

Good product.
I will probably give this product a better review when I use it in the spring. I have used it before and gave it 5 stars. Will have to see how it performs on prepping the surface of my motor home since I have "waxed" it with Poly Glo.
