How to Clean Soap Scum & Scale From Fiberglass Tub Surrounds
- 1). Soak the sponge in hot water, apply some dish soap, and scrub the walls of the tub enclosure down thoroughly.
- 2). Follow up with the nylon scrub sponge, scrubbing at any stubborn areas of soap scum or scale deposits. You can also use a clean toilet bowl brush for scrubbing, but make sure to wrap a pipe cleaner around the brush that's used to clean the shower so that you can tell it apart from the one used to clean the toilet.
- 3). Rinse the walls of the tub surround clean. If there are any spots of scale or soap scum still remaining, sprinkle baking soda on the sponge and scrub. Rinse clean once again.
- 4). Check the walls for any remaining deposits once again. If they're clean, you can towel them dry to keep water spots from forming and call the job done. If there are still hard-to-remove deposits, your options are to either keep scrubbing with baking soda and dish soap--the deposits will come off eventually if you're willing to invest enough elbow grease--or to wash the walls down with CLR (Calcium, Lime and Rust Remover).
- 5). Rinse the tub surround thoroughly if CLR was used; it has a strong smell, so you may need to let the water run for a few minutes, using the shower arm, if you have one, to wet the walls down. Turn the bathroom fan on, too, to help vent the smell out along with any extra moisture from the water running.
- 6). Towel the walls dry. If you get in the habit of toweling them dry after every shower, it'll help you go longer between cleanings.
