Fiberglass Hull & Bottom Cleaner, 32 oz. - CRC

Brown stains on a white hull could not be removed with mutations acid or scrubbing. This cleaner did the job easily.

I have used a lot of different hull cleaners and this product is head and shoulders above anything else I have ever used. I have a 30-ft express cruiser that sits in the water at all times. This product is going to make it a lot easier to keep the waterline clean and pristine looking. Rather than brushing it on, I transferred the cleaner to a spray bottle and after spraying waited for about 2-3 minutes and then wiped it off my waterline with a long-handle brush. Results were fantastic and I can highly recommend it for cleaning fiberglass hulls.

This year I tried On and Off for the first time on my 25 foot Sea Ray. The boat sits in a slip on the St.Croix River from May to October and the hull is not bottom painted. I poured 8'oz's of On and Off into a hand held paint bucket and applied as directed with a paint brush. I waited about 5 minutes and rinsed with a standard garden hose. My boat has never looked better. The pearl white fiberglass is back to like new condition. It took only 20 oz's to completely clean the whole boat from bow to stern. I was amazed I had 12 oz's left when I was finished. A little amount of this stuff goes a long way and provides great value for the price.

This product works as advertised. My boat had hardened and dried barnacles and other sal er crud on the bottom of the hull and OnOff did the job with some s ing. On the rest of the boat all I had to do was apply and spray and the crud came right off. I highly recommend. But beware, you must avoid skin contact, it is strong stuff.

I tried many products to get the water line and lake scum off my fiberglass boat hull, but with no success. I researched on i-boats.com for something that might work. When I read about On Off Hull Bottom Cleaner, I had my doubts because nothing had worked to that point. But I decided to give it a try, and WOW did this stuff do the trick. I brushed it on and hosed it off and my boat looked like it did the day I bought it. Great product that I would recommend to anyone.
