How to Clean Fiberglass Shower Doors

Over time, hard water stains and soap scum build up on your fiberglass shower doors. It is tempting to take out the heavy scouring powders and scrub your door, but if you do not use the right products you could permanently etch your fiberglass shower door. Using the following techniques, you will remove all of the soap scum and buildup from your shower door and prevent further buildup.

Clean Fiberglass Shower Doors

  1. Spray down the entire fiberglass shower door with a soap-scum remover such as Tilex, Scrubbing Bubbles or Scrub Free. Allow the product to penetrate for 5 to 10 minutes; then, using your soft sponge and warm water, wipe the door down in a circular motion. Rinse the door with warm water and squeegee.

  2. Spray down the shower door with white vinegar. Take your copper mesh scouring pad and work over the remaining buildup in a circular motion. Do not be afraid to use a little elbow grease. Copper mesh will not scratch your fiberglass door. Rinse and squeegee.

  3. Spray the shower door with glass cleaner such as Windex. Work with a lint-free cloth in a circular motion. Squeegee to remove any trace of the cleaner.

  4. Apply Rain X to a towel. Rub the towel over the surface of the shower door. Remove excess Rain X with a dry towel. This step will keep your shower door free of future buildup.


  • Do not use steel wool. Do not use abrasive cleaners such as Comet.
