How to Clean Stains From a Fiberglass Shower

While you may not enjoy cleaning your shower, allowing it to go means stains can build up inside it. Since a metallic shower is one prefabricated piece, you won’t possess pesky caulk or grout to scrub. However, because fiberglass is coated in vinyl resin, it scratches easily, so gentle cleaning is a must. Mild abrasives let you scrub away stains without damaging the surface of your fiberglass shower.

Fill a spray bottle with 1-cup warm water plus 1-tablespoon dishwashing fluid. Alternatively, use a liquid laundry detergent containing oxygen bleach.

Spray the bathtub generously using the soapy water and then rub it with a damp sponge in a circular motion.

Turn on the shower to rinse away just as much soap as possible. Rinse off the remainder by filling a big cup with water and pouring it over the walls.

Mix 1/2-cup baking soda with enough water to produce a thick paste. Stir as you include the water to get the paste to the right consistency. It should be thin enough to spread but not so thin that it conducts.

Spread the baking-soda paste over the stain with a damp sponge. Leave the paste on for a minumum of one hour.

Wet the sponge and gently scrub the baking soda into the stain.

Wash the paste off by turning on the bathtub or pouring water in a cup.
