We had stubborn algae stains on our PWC from several years of neglect. I tried a ton of different cleaners and nothing would cut it. A helpful associate at West Marine recommended this stuff and it absolutely works!!! I put some in a spray bottle and as soon as it hit the hull you could see it immediately dissolve the stains. I did small areas and washed it off immediately with a lot of water. So easy to use. I recommend that you read the directions and warnings, this is an acid-based product! Avoid getting it on any non-fiberglass materials. I got a small amount on my sponsons and it left white spots, however, it did not affect the decals.

Purchased On and Off on recommendation of West Marine. Was assured it would "instantly" remove everything from barnacle cement to waterline stains. It did neither. Made NO DIFFERENCE whatsoever on any stain! Will try to get refund from WM.

                    Have used a couple dozen different hull cleaners on several of my boats in the past and nothing comes close to working half as good as this stuff.

                    Took the roller marks off my hull in minutes.

                            Worked great, brush on and hose off just don't breath the fumes as it is quite toxic. Would use Hull Prep but can no longer find that product.

                              Very good product, expensive but works well with a pump sprayer. Caution when windy, the overspray will sting eyes (burn) and skin. Wear protective clothing.
