Best Hull and Bottom cleaner on the planet
Cleaning power is the best that I have ever seen for cleaning scum lines from salt water. I use a garden sprayer to apply a diluted solution. Just spray it on and wait 2-3 minutes and rinse off. Be careful with it. It does burn skin in the concentrated form and will take your breath away. Rinse your sprayer really good after use. Even a diluted solution will eat out the sprayer seals if left in the sprayer. Great product.

Really works! Removes the boat gunk almost instantly
This is powerful stuff. My freshwater boat had a huge scuz line that I hit with everything I had in the house and nothing touched it.On and Off took it right off.Be very careful, its very acidic, smells awful, but wow does it work!Used 1/2 a bottle on a 16 ft boat.

Works great on stain
The bottom and sides of my boat was a dirty brown that bleach wouldn't touch. This stuff instantly cleaned the brown spots. It didn't work as good on rust stains or black scuff marks but still an amazing product.. there is plenty in here to have cleaned my boat 20 times over honestly

good product
I was generally pleased with this product which did a reasonable job in removing stain from the transom of my boat which had been in the water (fresh) for almost a year. It's not magic and took two applications and a lot of scrubbing but it certainly helped.
