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.

My boat's white hull bottom gets that brown, tea stain from water line down even after just a weekend of sitting in the lake. I used to use muratic acid to clean it which is a dangerous chemical. I purchased Biokleen Oxidation Remover-Fiberglass Stain Remover just to try since it wasn't expensive. I AM BLOWN AWAY! Used it for the first time last weekend. Just sprayed it on and by the time I got back around to where I started the brown stain was gone! I just did some minor wiping. This stuff is amazing and biodegradable. Thank you, thank you, thank you! Love the milky white hull of my boat again.

I've purchased this product again because I ran out of it. It's Awesome! I fish a lot in a brackish water river that always leaves a skim line on the hull. I juat spray on Biokleen, hose it off and instant bone white hull again!! I'm a lifetime costumer!!!

Holy cannolis! It’s a miracle!! For years I have been using that nasty awful instant hull cleaner (that’s an acid) to clean the yellow/orange discoloration off the boat hull. Unfortunately, it was the only thing I found that worked. I had to wear gloves because it will eat your flesh off, and it is horrible for my aluminum trailer. Now with Bio-Kleen Oxidation Remover, just spray it on, and the boat turns back to bright white! As far as I can tell, it’s not harmful like the acid was. I’ll definitely be re-ordering it, and by the gallon next time.
