Great product. Took me half the time to clean my pontoon boat this year. Will continue to use product.

This is a top three product in my boat detailing arsenal. It removes deposits easily, efficiently, and I can use it on fiberglass hulls or aluminum pontoons.

Hull Kleen did ALL i expected on a very, very neglected aluminum hull.

I have tried every product online and on the shelfs and nothing would touch the white crust, algae, grim on the bottom and sides of my jetski even with heavy rubbing. I just received this Hull Kleen and sprayed it on and within seconds all the bad built up stuff was literally falling off my jetski. I didn't even have to rub it with any brush or cloth. This stuff is amazing and I will tell everyone about this amazing product. I am sold for life and will always use this!

This product works ok if you clean the Pontoons on your boat at least once a year. I will use this next year. This year I needed something much stronger since it has been 3 or more years since the pontoons were cleaned.
