One of the most common materials used for bathtubs and sinks is fiberglass. An important key to making fiberglass last as long as possible is keeping it clean. Sometimes, stains can set in and be a serious pain to remove. Here are a few ideas on cleaning tough stains and routine cleaning for fiberglass.


Be sure to always use a non-abrasive cleaner due to the shiny nature of fiberglass. Some examples include:

  • Hand dishwashing liquids or liquid laundry detergent
  • Bathroom cleaners or all-purpose cleaners
  • Baking soda moistened with water to create a paste, rubbed on surface with a sponge or soft brush
  • Soft scrub products


Read all instructions on whichever cleaning product you decide to use and apply to the surface with a sponge or non-abrasive applicator. Avoid using any common scouring powders, abrasive scouring pads, steel wool or scrapers. Using these will cause scratches on the fiberglass and ruin the pristine shine.


Occasionally, there will be a stubborn stain on your fiberglass that will need more attention than routine cleaning. If there is a stain that won’t go away, sponge any of the previously mentioned cleaning products on and let it sit for at least an hour before rinsing.


Tougher stains such as tar, iodine, or oil-based paints can be removed with any acetone nail polish remover or a paint thinner. Take a white cotton cloth and saturate it with the solution, then lightly rub the area until the stain is removed. These solutions should be used sparingly for major stains. Work in a well-ventilated area when using them and avoid smoke or open flames when cleaning. Also, use a damp cloth to wipe the surface and don’t let the solutions go down the drain.


Taking the time to clean your fiberglass fixtures is extremely important and will be well-worth it in the end. Extend the life of these pieces by wiping them down daily and giving them a good deep clean weekly.
