Instant Hull Cleaner

Most excellent hull cleaner I have ever used. I wish I had taken "before" pictures for you. THis product saved me HOURS of hard scrubbing and back breaking work. Our hull always comes out of the water severely stained with a crusted surface of burnt orange from tamarack in the water and heavy stains and water lines. It doesn't come off. In the past, I have used toilet bowl cleaner and heavy brushes and scrub pads and with a beam of almost 7 ft, you cannot reach under there far enough to get at the keel, so it stays dirty, as do the other places you can't get at. So it just builds up year after year. This year, I bought Star Brite, sprayed it on, let it sit for a couple minutes and sprayed it off. In places that have never gotten cleaned before, I had to do a second app and sometimes a third. I have very little water pressure, so the hose was not an effective tool, just saying. But with repitition, it would keep coming off. In about an hour, this boat was spotless from stern to bow. Just beautiful!! Worth every penny. I'll never use anything else ever again. Do use rubber gloves and a mask because of wind overspray.

This product is nothing less than amazing. Previously I spent hours using rubbing compound to remove brown hull marks. With this product I simply spray it on and within 30 seconds the ugly brown scum is gone. I can't say enough about how great this product is.

Worked well! My boat was pretty bad with stuck on algae and it got almost all of it off without scrubbing. A thick brush and the rest should come right off!

worked great, but I did need two applications and I felt like I used more than I should have needed. At the end the boat was perfectly clean and that's what I wanted!

This stuffs insane. Within seconds the lake scum from letting my boat sit for weeks in the water just falls off. I used a round up sprayer and sprayed on, brushed even though I dont think I needed to and sprayed it off. Some areas took 2 rounds but the whole gallon is enough to do my 19' tidewater twice.

I tend to write reviews on either good products or bad products. This product is AMAZING and saved me HOURS. As others have stated the bottle did leak a bit upon delivery, the bag inside had some moisture and the seal had broken, maybe 1-2 oz. had leaked. Not the end of the world. I had this product, a Ryobi powered sprayer which I emptied the entire gallon into. (ASIN - B07SYC7JM2). It holds 95% of a gallon. As for what scum I was trying to remove. We keep our boat in the water 6 months of the year. Our boat is a surf boat with surf gates, fresh water exhaust, swim platform etc. These various parts including the metal parts seem to really cake on slime and scum. Last year I tried 4-5 different products, Magic sauce, vinegar and baking soda, a scrub brush, a 3200 PSI power washer, even a powered handheld dremel brush. I, eventually after multiple days of work, got most of the scum off but hard to access parts and in cracks (especially metal - power wedge and FAE) was near impossible. I sprayed roughly half a gallon all over and before I even got back around to where I started the scum was dripping off. I rinsed and repeated in some spots, like the FAE, rinsed again. No joke, our boat looks brand new. Never been more amazed with how much time this saved, how well it worked, how much little effort it took, and the overall results. As long as we have a boat, I'll be buying this twice a year. Bonus - even applied a little to the trailer and same result!

This brand has yet to disappoint, every product I’ve tried does exactly what it says, and this is no different

Was very disappointed that the gallon refill jug was NOT jelly form. It applies very watery and runs right off. I had the 32 oz jell bottle and really liked how it applied and worked. Not so much with the 1 gallon refill. The bottle in the ads look so much alike I didn’t notice that it didn’t say Jell.

利根川・猪苗代湖等で淡水使用のスキーボート数年間洗っていなかった黄色～茶色っぽいひどい水垢汚れ自宅にあったマジックリンでは全くだめパーツクリーナーでも全くだめ3Mのボート用クリーナーワックスを使ってみたが全然汚れが落ちない…ユーチューブでスターブライトのクリーナーを使用して汚れが落ちている動画を見てためしに購入してみたらバッチリ動画の通り汚れが落ちました。最初からこれを使っていれば良かったと思いました。おすすめです。
