Don’t spend all your time trying to remove water spots after a day on the water. The newly improved formula for Gnarly Marine & Boat Water Spot Remover uses fruit acids to break up and dissolve lime, mineral deposits, and similar contaminants that have dried and bonded to the surfaces of your boat without stripping the wax. Just spray on and wipe off to get your gel coat, chrome, plastics, paint, and glass clean in a hurry. Our unique formulation includes polymers that don’t just clean but also protect your boat.

  “The spot remover spray works well. I have a white boat…I found some water spots that have been on my boat for about 3 weeks now and they easily came off with a little product and just wiping with a cloth. What I did notice is that the smell is very very subtle compared to other products I use or have tried. It’s a good smell but not overwhelming, so if someone doesn’t really care for the smell, it will not stop them from buying your product because it is so subtle.” John R. – Axis Wake Forum 2013
