This product actually delivers on its promises! It took of years worth of road film and grime from our motorhome..leaving a clean base for the application of Poli Glow polish... Our motorhome is now looking shiney and new again. Very easy to use..just mop it on..let set for a few minutes then pressure wash off.

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!
