DIRECTIONS: Ready to use. For the yellow hue on a boat hull: Spray on, let stand 1-10 minutes, allowing longer time for salt water conditions and heavy build up. Rinse thoroughly or wipe thoroughly with a clean, cotton towel.



For dull, chalked paint on an rv: Spray on, wipe clean. Agitation with a soft bristle brush may be required on boat and rv surfaces with heavy water mineral build up. Follow up with an application of RV Wax to prevent future build up and create a layer of UV protection and shine.

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.

<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>
