How to Clean Fiberglass Bathroom Surfaces?

You might be a little lost when it comes to properly cleaning your fiberglass shower or tub, but you certainly aren’t alone. Wear and tear create stains and scratches on your bathroom surfaces, and usually they’re pretty easy to tackle. Fiberglass surfaces, however, are more of a challenge to sanitize because of their sensitivity. Clean, remove stains, and preserve your fiberglass bathtub or shower to keep it looking new.

Select or create a non-abrasive cleaning solution. For a general cleaning, fill a bucket with warm water and add a squirt of liquid detergent. Add more soap to your bucket if you think you’ll have a tough time cutting through stubborn dirt and grime.

Opt for non-abrasive cleaners such as dish and laundry detergents, household all-purpose cleaners, bathroom cleaners, or baking soda. Avoid abrasive cleaning products, such as scouring powders, since these can cause damage to your fiberglass bathtub or shower.

Apply the cleaning mixture with a non-abrasive applicator. Dunk a soft sponge in your bucket of warm soapy water and gently scrub the surface of your fiberglass shower or tub. If you don’t use a soft sponge, make sure that your applicator is made of nylon, polyester, or polyurethane.

Do not use scouring pads, steel wool, or scrapers because they will be too harsh on the fiberglass. Rinse away the cleaning solution and dry the surface with a towel. Let the cleaning solution sit on your fiberglass surfaces for about an hour. Afterward, rinse the tub or shower thoroughly with warm, clean water and dry it with a hand towel.
