This is miraculous!!! I’ve tried everything to get the hard water spots off our fiberglass. Our boat is on Lake of the Ozarks and the lake’s water is very hard!! Sprayed it on, left if for 15 minutes and wiped off the spots.

Bought at Bio-Clean the winter sale. The video for clean toon made it look simple. Guess what it is simple.Sprayed it brushed it in let it sit hose it off. Did take 3 applications to get the toons 95% clean but the i am sure these toons where never cleaned in the boats life(17 years). Will i tell friends about it? You bet.

It runs down a vertical surface and you need to work it right away. But it works well with w little scrubbing with scotch brite pads.

I have used this on two boats now to clean both the hulls and the out drives, it works incredibly well and with very little effort. I have even used it on my Ford pick up running boards and they came extremely clean where many other products i tried would not make a dent in the scum that was on them. This is a great product. Bio Clean just needs to do something about he shipping costs they are very high and make the product hard to buy

This product removes dried on skum, slime, and whatever that sticks to our boat when we leave it in the water for days. It removes stuff that nothing else would. Our boat went from a rough, white caulk film to a smooth, shine surface again. This is a great product!
