Hull Cleaner Gel Spray

Great Hull Cleaner — Works Fast and Makes Boat Look New! We recently used this hull cleaner on our boat and were very impressed with how well it worked. This product quickly removed waterline stains, scum lines, rust marks, and general grime without a ton of effort — just spray it on, let it sit briefly, then rinse off. What We Liked: ✔️ Easy to use — no heavy scrubbing or elbow grease needed; it dissolves stains almost instantly. ✔️ Very effective on fiberglass and painted surfaces — even tough stains like brown water line marks and fish blood came off. ✔️ Quick results — made a noticeable difference in appearance in minutes. ✔️ Great prep before polishing or waxing. Notes: 💧 Make sure to follow instructions and rinse thoroughly after applying. 🧤 We used gloves since it’s pretty strong and works best when handled carefully. Overall this has been a great addition to our boat care routine — cleans deeply and saves a ton of time compared to scrubbing by hand. Would definitely recommend it if you want your hull looking sharp again!

I was very skeptical at first, with how easy it said it’d be to use, just spray on and rinse off and the brown slime would be gone and boy was I wrong. Literally just spray it on wait a couple minutes and rinse off, took the brown slime right off. Amazing. One bottle did my 19ft boat with some left over. Every effective, no scrubbing, very easy to apply

I don’t even own a boat. What I do own is a shower that had a nasty floor that no amount of scrubbing with many various kinds of cleaners would ever come clean. It was an embarrassment to even have guests use this shower. I was extremely hesitant to order this because of the price and the fact that several reviewers said the spray bottle kept getting clogged. But desperate times call for desperate measures. What a bargain even if I have to buy a new spray bottle every time I use it. Two applications and a bit of scrubbing and my shower looks brand new. I have less than 10 minutes total time in cleaning this shower. So I can’t tell you how it works on a boat hall but I can tell you on a fiberglass shower, it is amazing.!

Works but needs tons of scrubbing and have to keep on spraying it worth the $ if you have the time to work on it

Amazing! I was unaware that you aren’t supposed to use abrasive things on fiberglass. We moved in an old home with stains on the tub that just refused to budge. So I got some of this. I sprayed it on and could see before my eyes that the stains were getting lighter. In a rush I got my else electric scrubber out nothing at all was happening when I was a rubbing while the rest continued to get lighter and lighter. This was a salvaged tub because precious owner went as cheap as they could to update the home. So I am continuing to spray is every few days and it continues to lighten. When it’s cleaned well, I will put a sealant wax on it. I can’t believe I spent 9 years of extreme effort into cleaning this tub when there is a product that I can just spray on a walk away.🤦‍♀️ There has been no leakage. It couldn’t be easier to use. Our bathroom isn’t very ventalated so I can’t spend much time spraying because I have to leave because it dries out my throught. It is extremely effective.

Best hull cleaner around !! Melts the nasty off the bottom no need to scrub !!

Sprayed on and waited 2 min, results were mild hard water came off. Scrubbed 2 min straight with a hard bristle brush, results were better. Scrubbed second time, no scum line removal, or heavy deposits removed. This is an incredibly mild product, and i had better results from concentrated vinegar. 3 Star for the gel application allowing for more even distribution, would not recommend at all for hard water deposits or scum line removal.

This stuff is amazing!! Best toilet hardwater cleaner ever!! I know it’s for boats, but it works wonders in the bathroom toilet 🚽 bowls too! I will try this on all my toughest stains.. it works for me and I love the gel helps it stay in place! Get it and thank me later!
