## Customer Reviews

### ⭐⭐⭐⭐⭐ Amazing results!
*by M***Y on October 9, 2018*

Unbelievable! My sailboat was in the water all summer on a mooring ball. I was so worried about the green slime.After pulling it out and spraying off I looked at the brownish green stains and thought it would never be white again.I applied FSR and literally in moments it turned white again. I am so pleased. It takes no time at all and worked like magic. Washed and waxed after and it looks almost brand new.

### ⭐⭐⭐⭐⭐ Look no further
*by C***Y on July 2, 2020*

I heard from my boat group that this works well. I have to disagree...it is awesome!!! Used it on our new to us 2014 boat with the brown stains along the bottom. They came right off !! I had tried other cleaners, nufinish and magic eraser with no luck. This stuff was unbelievable. I didn’t even have to scrub, wipe on wipe off. Well worth every penny :)

### ⭐⭐⭐⭐⭐ Works great!
*by T***K on July 31, 2019*

Holy cow, this stuff was amazing!My hull had orange/yellow salt water stains.Initial washing with soft scrub was somewhat successful but the hull still showed discoloration.A simple wipe of the FSR gel and the white hull cane back immediately. What surprised me most was the zero effort or rubbing required. Really, wipe on and wipe off.A skeptical boater is now a fan.Thank you!
