I have used On-Off to clean the entire hull and fiberglass decks. After long mooring times the hull comes clean with almost no effort. I wipe it on using a brush full strength on a dry hull. Use very small amounts in a pail and dry brush to apply. Let is rest on the hull for a few minutes, not to dry they dip your brush in water and begin to scrub. Add water to keep the area damp. Two or three light strokes and hose it off. Nothing works like On-Off and it's especially great at cleaning tuna blood that has dried on. Excellent for cleaning bilge areas but be careful to keep it off metal, it will remove galvanizing. Most important to use in a very well ventilated area. Not for a careless user.

My boat is a 1984 FourWinns(hull color is beige). It is used on a man-made lake in Pa. Every year when it's time to pull her out of the water for the season the hull is the color of dark roast coffee(blackish-brown). Last year when I stored my boat without the usual in-depth winterizing and cleaning I dreaded the spring clean up. This product saved me a week of hard work. Within seconds the hull was clean where ever the product was applied.ON-Off is one AMAZING product.

I sprayed this stuff on the bottom of my runabout and that dried on green film that just won't come off literally melted away even before I finished spraying. I then took a long handled soft brush and just washed it around and then rinsed and the bottom was clean as new. This may be the best product I have ever used as far as doing what it says it will do. READ AND FOLLOW THE DIRECTIONS, WEAR GLOVES AND DON'T GET IT ON YOUR SKIN. THIS STUFF IS SERIOUSLY STRONG.

i tried this stuff out cause my marina told me to i keep my boat docked in fresh water it is not bottom painted just has gel coat and i took the boat out and it was a disaster i thought i would never get it clean i tried using 3m rubbing compound to get it off and even with a buffing wheel and the strong compound it wouldn't budge took off a little but noting near what i wanted the whole bottom was done went to the store picked up a bottom what did i have to lose i sprayed it on the boat whole used windex top to spray it with and all of a sudden i seen smoke after the smoke i just seen the ick running down the hull i sprayed the bottom side the whole hull of the boat within minutes the boat looked like it just came out of the show room compounded and waxed it and wow made my boat look like brand new it burns ur hands so wear gloves you are dealing with acid and try not to breath any fumes in the stuff is strong but it is magic so just be amazed when u go to clean

I've used On- Off for many years on my fiberglass/gel coat boat. I'm in staining fresh waters in the Midwest. I wipe my boat down after every use, but staining is still inevitable. I use On-Off to remove this stain once or twice a year. Handle the product with care as directed. I simply sponge it on and rinse immediately. The staining is removed instantly. This must be followed up with a good protective coating, I wax.
