Greg Kissel on Hull oxidation remover

Tried the BioKleen oxidation remover on my boat with yellowed stains from river tannic acid. BioKleen works better than Attwoods hull cleaner product and at 1/2 the price. The BioKleen people are professional fast and courteous. If you try it once I guarantee you will never go back to the old products you used in the past. For the naysayers... Biokleen didn't pay me a cent to review their product and write this summary.

Better than advertised

<p>I keep a boat in saltwater environment most of the year. I fight the yellow water line all the time. I saw the Youtube video on this stuff and could not believe it works that well. It does and then some. I was blown away by how fast this stuff worked and how good a job it did. If you own a boat get this stuff. YOU will not regret it.</p>
