Like a teeth-whitener for your boat!
By Sisters'ships from Great South Bay, NY

Works incredibly well. Have used other brands before. This is at least as good as any I've tried.

Amazing Product
By Susan from Canada

Verified Purchase

I bought this to see if I could remove the river water stains from our boat. I had tried everything from degreaser to scrubbing. This product is amazing! Some areas I had to apply 2 applications, but it all came off. I highly recommend this.

Very impressive!
By RLW from Tiverton, RI

I watched Louis' video, which was quite compelling. One of my sailboats has chronic fouling at the overhang, which is a tough location to maintain. That would be the test. Well to say it passed would be an understatement. The picture of before and after says it all. Thanks JD!

Good Buy

Use this product for the first time it looks like something else I use to use, tired it on a yellow stain and you can see work.

Great at cleaning scummy hulls
By Nick from Seattle, WA

Verified Purchase

Just like the videos, I just painted it on and the discoloration/ dried scum on my hull just disappeared after a couple of minutes. I found a few spots that I missed and hit again with a second pass and it came out perfectly clean with no effort.

White Knight is amazing
By kaiabrew from Falmouth, ME

I used this on our 1995 Mako. Lots of Iron staining here in Maine. Used by instructions and our haul came out amazing. Highly recommended. Great value.

Excellent Product
By Kind of Blue from Jamestown. R.I.

Verified Purchase

My boat lives on a mooring in season and by fall the hull always has yellow staining above painted bottom. You simply apply this product and the staining disappears before your eyes. No elbow grease required, simply apply on stained fiberglass, wash it off and you're done.

Removed brown stain from white hulls on three small boats. Stains were gone in about one minute. Still have half the 16oz left!
