Hull Cleaner Gel Spray

Cleaned up our jetski with minimal effort. Spray on, let sit, wipe off. Got rid of weeks worth of brown water build up. Little goes a long way.

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 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.!

Tough to work with. Had to use it twice first go left white chalky residue. Dod work but you have to be quick

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.

This stuff is amazing! I was helping a friend with his boat and the bottom was covered in lake muck. We tried a pressure washer and it did very little. I bought this stuff and it worked in minutes. If you want lake scum off your boat fast and easy this is what you need.

Does not really clean a stain. I tried to use it on my boat as well as jacuzzi, you can see just a bit better after the cleaning, but not even close to what others are saying. I would definitely would not recommend. I ordered two of them, because of the reviews but regret it. I used one of them completely, still hopping that I am doing something wrong, however to real result.

I don’t even own a boat. But, the only thing that I have found in the past to clean my fiberglass shower is a Zep acid toilet bowl cleaner. However the smell is harsh and I have to keep coming back because the fumes are too much. ChatGPT pointed me to Starbright, so I bought it…one spray and immediately it’s clean, with no scrubbing. I would give this 10 stars if I could!! Not sure how it works on a boat, but it’ll work incredible for your shower..
