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.

I elected to have to put quite a bit more effort into getting the bottom cleaned I just sprayed on and washed. Hit the stubborn spots a second time and was done.

I have a 2005 Triton Bass boat that I use 30-40 times per year. The boat is solid white with a gray stripe. Over the years of fishing in muddy, and stained water, the side of the boat and hull that are under water while off the trailer began to take on an off-white appearance. I could remove the stain with wax and a lot of elbow grease but this product from Bio-Kleen took care of the stain in a matter of minutes. I just sprayed onto the effected areas, allowed a few minutes and wiped the areas with a soft cloth, NO SCRUBBING REQUIRED, I then hosed off the areas with a garden hose. The product completely removed the water stain. I did notice the next time out while wiping down the boat that I had to work a little harder to remove the water line from the trip but that was due to not applying a good coat of wax back to the surface after cleaning, which the product recommended. I have since done this and now boat wipes down spotless everytime.

Great product, highly recommended.

This product is truly amazing. We used to spend hours trying to scrub the yellow scum off our boat. We literally sprayed this on and rinsed off a few minutes later. No scrubbing even required!

Works very well for yellowing spray it on then wipe it off. some scrubbing on stubborn spots but works better than anything I found.
