5 Easy Steps on How to Clean a Fiberglass Shower

While regular maintenance goes a long way in keeping your fiberglass shower clean, it’s essential to give it a deeper clean periodically. Here are some effective techniques for deep cleaning your fiberglass shower:

  1. Create a baking soda paste: Mix baking soda toward with water in a small bowl to create a paste-like consistency. Apply the paste to the surfaces of your shower and let it sit for 15-20 minutes. Baking soda is a gentle abrasive that helps remove stubborn stains and soap scum without scratching the fiberglass.
  1. Scrub with a non-abrasive sponge: After the baking soda paste has had time to work its magic, use a non-abrasive sponge or a microfiber cloth to scrub the surfaces of your shower. Work in gentle circular motions, focusing on areas with buildup or stains. Rinse thoroughly with water.

Vinegar is a natural disinfectant and helps dissolve soap scum and mineral deposits. Scrub with a soft-bristle brush or sponge, then rinse thoroughly.
  1. Pay attention to the showerhead: Over time, mineral deposits can clog the spray nozzles of your showerhead, affecting water pressure. To clean the showerhead, fill a plastic bag with vinegar and secure it around the showerhead using a rubber band. Let it soak for a few hours or overnight, then remove the bag and scrub away any remaining deposits with a brush. Run hot water through the showerhead to flush out any loosened debris.
  1. Remember the grout: If your fiberglass shower has grout lines, it’s also essential to give them some attention. Mix equal vinegar and water in a spray bottle and spray the solution onto the grout lines. Let it sit for a few minutes, then scrub it with a soft or old toothbrush. Rinse thoroughly.
