Instant Hull Cleaner - Removes Stains & Grime

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.

STAR BRITE Instant Hull Cleaner made cleaning my boat hull so much easier. The wipe-on, rinse-off formula quickly removed stains, scum lines, and grime from fiberglass and painted surfaces without scrubbing hard. It’s convenient, effective, and the 128-ounce size provides plenty of product for multiple cleanings. Highly recommend for boat owners.

There is ""NO"" better hull cleaner - period..! 10 stars..!

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!

We have hard water, with lots of minerals. I was always complaining to my husband, that the buildup on my stainless steel kitchen sinks was infuriating! I have tried multiple cleaners that are on the market, but nothing worked well. Then, I tried using vinegar, but even that did not work either. He has used this hull cleaner on his boat and suggested that I try it on the sinks. I did not have anything to lose, so I did. I put on latex gloves to work with the product because it is a mild oxalic acid formula, and felt that it would be safer on my hands...my choice, not necessarily recommended by the manufacturer. I poured the product on a cleaning cloth, but now I put it in a spray bottle, which makes it easier to apply. What surprised me, was how well it cleaned the sinks. I did not even have to repeat the application. I did make sure that I rinsed the sinks well with water after use. I am much happier now. ; )

Product worked well to clean the muddy film on my boat without streaking. Rinsed off well. I did have to scrub the area where the boat had sat in the water longer.

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!

Worked well taking most of green stuff off of bottom of boat. However there were a few spots that required a lot of extra scrubbing. Would be better if it was slightly stronger. Much cheaper than having the marina clean the hull.

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。
