I have what appear to be hard water marks in my fiberglass bathtub that I would like to try to remove. Also, is there a way to restore the gel coat in a fiberglass bathtub?

      Hi...I have used Wet and Forget to remove moss that started growing on my roof, but I did not know it would work in a fiberglass bathtub... My concern is for the gel coat not getting damaged.

  • Here's what I use for hard water stains:

    Fill a spray bottle with a 50/50 solution of Dawn dish soap and vinegar. Spray it on the hard water stains and let it work. If they are tougher stains, you may have to scrub with a plastic scrubbie!

    Works every time!
