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.

Bad Bottle??

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...Read complete review

USA Formula good, Canadian not

By Pacific Raven

from Vancouver BC

Pros

  • Easy To Use
  • Works Effectively

Cons

    Best Uses

    • Marine growth, barnacles

    Comments about On & Off Hull/Bottom Cleaner:

    Very strong, rapidly dissolves barnacles which I frequently do in Mexico if I leave my RHIB in the water too long. Very caustic, eye protection and skin protection are a must, and you must use upwind as a strong intake of the fumes is very caustic. This is a serious product. But beware - the Canadian formulation is much weaker and will not dissolve barnacles like the USA formula.

          • Boat Hull

          Comments about On & Off Hull/Bottom Cleaner:

          We had left our boat in the Sebastian River for a week with no bottom paint and the stain on the hull was a dark orange. I used on and off and that is exactly how easy it was - you put the product on and rinse off and the hull was shiny white again... A truly amazing product.

                  Have used this product for years and always has been effective to remove rust stains and any other things that normal cleaners don't remove. The name says it all spray it on and wash it off......I actually dilute the product with water in a spray bottle and spray the areas needed otherwise the product is very strong. BE CAREFUL!

                      Very impressed. Have a boat that sat for 4 years and had water rust all over it. Tried many different products that did absolutely nothing. Took 3 spray down and wipe off and it was completely brand new looking

                          Was sold this product after asking about availability of another. Will never use anything else. Cleaned hull to original white perfection without a lot of effort. Highly recommend.
