### ⭐⭐⭐⭐⭐ 







  
  
    Amazing product
  

*by S***E on Reviewed in the United States on September 11, 2020*

This stuff worked awesome on our pontoon.  Our cover sprung a leak and mildew grew quickly.  This stuff is amazing, you spray it on and watch the mildew disappear.  Made our seats look like new again.  4 months later, the mildew has not returned.  Make sure to buy a good vinyl conditioner to apply after use, this stuff has a high bleach content and could break down the material.  Boat seats should have UV protection applied regularly anyway, so i use a conditioner with uv protection in it. Attached before and after photos of two of the worst areas.

    THIS STUFF REALLY WORKS!!!!!
  

*by T***. on Reviewed in the United States on July 24, 2021*

This stuff is amazing, I tried everything to get the mildew stains out of my pontoon boat seats and was very skeptical of this stuff. I read the reviews and decided why not give one more thing a try and boy am I glad I did. This stuff is like no other product out there. Simply spray it on, let it sit for five minutes, and watch it work. After five minutes just lightly wipe with a damp cloth to remove the loosened mildew and it's done, that simple.

    Damaged the vinyl coloring on first use!
  

*by B***R on Reviewed in the United States on November 29, 2020*

Of course the jug doesn't list the ingredients but I can tell you that's it's nothing more than diluted bleach.It claims to be safe for [marine] vinyl but I can tell you that it took the color off the small spot that I tested it on.  I used *maybe* a few drops of the stuff and the coloring ended up on my towel.Absolutely not safe for vinyl.
