Review: Miraculous. WORTH EVERY PENNY. - 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!
Review: Works well and quickly - This cleans off a summers worth of grime in minutes. Magic eraser did an OK job with “elbow grease”, this product removed it instantly, and didn’t harm the grass under the boat. In the picture: left side is star bright (until I ran out); middle section is magic eraser, right side is how it came out of the water.

## Questions & Answers

**Q: what is the main ingredient?**
A: Instant Hull Cleaner utilizes oxalic acid as a cleaning agent. 
Please call our Tech Line at (800) 327-8583 if you need any further information.

**Q: Does it kill grass ?**
A: The action of rinsing Instant Hull Cleaner off the boat dilutes it to such a small amount that it should not harm the grass. We would suggest wetting the lawn Before you apply Hull Cleaner, rinse the cleaned hull thoroughly and then wet the lawn again afterwards.

**Q: Will this damage bottom paint?  Thanks**
A: Yes; Any contact with any type of cleaner can damage or otherwise remove bottom paint which is why you should not attempt to clean it.

**Q: Will it harm any decals on the boat?**
A: In order to ensure there is no damage to inferior quality decals or other graphics, avoid contact with decals or stripes - rinse immediately if contact does occur.

### ⭐⭐⭐⭐⭐ Maybe an odd solution, but it works inside the house too...
*by K***D on October 15, 2025*

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. ; )
