On-Off Hull and Bottom Cleaner

I moor my boat in saltwater so you can imagine what the hull looks like after the summer.I use to use soft scrub w/bleach took me 2-hrs to do my 21 ft boat,I applied this with a paint brush let it sit for 60 sec...GONE..took 30 min.to do,and no sore muscles.This stuff is great.

I've used On- Off for many years on my fiberglass/gel coat boat. I'm in staining fresh waters in the Midwest. I wipe my boat down after every use, but staining is still inevitable. I use On-Off to remove this stain once or twice a year. Handle the product with care as directed. I simply sponge it on and rinse immediately. The staining is removed instantly. This must be followed up with a good protective coating, I wax.

Spray on Boat Hull, Rust Stain, or Organic Stain. Works in seconds without smell or burning! Do not use on glass!!

This stuff works great had a customer with a boat that had red clay stain from the lake on the hull. This stuff cut right threw it and took all of it off and even the rust stains. But beware this stuff will burn your eyes, skin and lungs so wear all the protection it recommends. I highly recommend it and will be using it in my business for now on.

Very powerful stuff, use as directed and you'll be amazed with the results.

This product works better than you may expect. It is important to read and follow all the directions but the performance and results are exactly as advertised.

I used it to clear a very heavy growth from the waterlne and areas of the bottom and rudder. It powers right though and took it down to a clean surface in just a minute. Use rubber gloves and a sponge with a scrubby side to knock off the heaviest stuff.

This product really does work as advertised. I will find another product though that has less toxic chemicals. The smell and vapors scared me. The warnings all say not to let this product get into the water supply. Barring a recovery system, that's impossible. This stuff is too scary to use in good conscience.

Applied product to boat hull as per directions and was amazed at how well and quickly the cleaner worked. Neighbors have already purchased the same product to use on their boats.

On-off really does a great job on those nasty stains. Easy to scrub off those brown waterline stains. Works well on green bottom slime as well.
