    The fairings and saddle bags on my bike are fiberglass as well. The cleaner I use will take week old dead bugs off in an instant. Tar and oil too. Leaves a beautiful shine. My bike is 900 pounds and Pearl White. A whole lot to get oily and dirty, this stuff cleans it up fast. I’d go get the name but it’s in the garage and it’s storming right now. LOL

    What solutions do you recommend for cleaning fiberglass shells? Obviously, abrasives should never be an option.

      There are many things you shouldn’t ever begin using abrasives on. Once you do, you’ve created microscopic grooves. I’ve been preaching about abrasives for years.
      If you thought it was so bad it needed to be sanded off this time, wait till next time.
      Examples? Your new toilet bowl. The tile on your new swimming pool. Your new aluminum cooking ware.
      Water is the world’s greatest solvent.
      If I were hired to clean a hot tub that had not been damaged in this way.
      I would have a pump in the footwell.
      I would use a water and chlorine solution, not too strong. Then rub and rinse at the same time with a terry cloth towel. If that does not remove everything quickly the next step for me would be a product I use on my motorcycle. It’s a waterless spray cleaner found at the auto parts store. I use it all over, including on my windscreen.
      This will get it clean, then another scrub down with my towel and chlorine solution.
      Damaged units will get the same treatment plus a mild acid solution only if it has scaling holding on to the funk in the micro cracks.
      Sanding down the damaged area again is not a good plan.

        I have heard boat cleaners are ideal because boats are made of the same fiberglass material that pools and spas are!
