How to Clean Scum off a Fiberglass Bathtub


Fiberglass bathtubs withstand many years of use and are heavily resistant to stains. However, dirt, soap and body oil can leave a layer of scum on the bathtub surface over time. This scum is unattractive and often contains harmful bacteria. It can also create a slippery surface on your bathtub that can lead to a slip or fall. It is important to remove the scum and implement a regular cleaning routine that keeps the build-up to a minimum.

Things You'll Need

  • Spray bottle
  • Vinegar
  • Dish detergent
  • Water
  • Nylon scrubber sponge
  • Baking soda
  • Fill a spray bottle with 2 cups of white vinegar and 2 tbsp. of dish soap.

  • Spray the solution onto the fiberglass bathtub surface. Wipe the tub with a wet nylon scrubber sponge.

  • Rinse the bathtub with hot water.

  • Sprinkle a light coating of baking soda over remaining residue. Scrub the tub again with a nylon scrubber sponge.

  • Rinse the bathtub again with hot water.

Tips & Warnings

  • The vinegar disinfects and cleans while the dish detergent assists in cutting through the scum. The baking soda gives a slightly abrasive texture that cuts through the residue without scratching the fiberglass.
  • Spray the bathtub every few days with the vinegar and dish soap solution, then wipe it with a wet cloth to keep scum buildup at a minimum.
