Instant Hull CleanerGel

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 had old hard water stains on my boat. See photos. I couldn’t get the stains off. This was the easiest and simplest way of getting rid of them! Took literally two minutes! Spray on - wait two minutes and rinse off! Didn’t even have to scrub. Now it’s my go-to product!

Holy Smokes! This product is the bomb! Having read many reviews when purchasing the Star Brite, I had high expectations for this cleaner to do wonders on the waterline of my boat; however, I had no idea how effective it was and easy to use. No heavy scrubbing needed, just follow the instructions…

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

This is my go-to when it's time to get my boat all clean and ready for the season. I keep my boat in a slip on the ocean, and it gets a nasty tannin stain above the water line. This product gets rid of the stains, and even removes stubborn rust stains below my pump-out fitting, bilge pump fittings and gas vent. It's a must-have!

WOW... this is by far and away the absolute BEST cleaner for a boat when you take it out of the water and have the brown stains on the hull.... Spray it on, let it rest, then just WIPE it clean and it looks as good as NEW..... I tried lots of other cleaners and chemicals and this works the best!

I bought a used boat that had been docked for years when not being used. The boat had an ugly brownish green bathtub ring that looked impervious to cleaning attempts. I bought this bottle of Star Brite with low expectations just because the stains were sooo bad. I did just what the directions said. Spray on - wait a few minutes - spray off. OH MY!!! The stains just washed right off. I wish I had taken 'before' pictures so you could see the miracle. I highly recommend.

Cleans well but the nozzle stops working after about 10 min sucks when your old and laying under the boat 2nd time come on up your game
