Bathrooms are made to be used. And with frequent use comes dirt and grime and soap scum. Any surface that comes into contact with soap and water will eventually see soap scum build-up—especially if your water is of the hard variety. If left untreated, soap scum build-up can be difficult to remove, so it’s best to stay on top of soap scum removal. Follow our tips for keeping your bathroom clean and soap scum-free!

Sink Faucets


Soap scum can be most obvious on metal bath, shower and sink fixtures, forming stains that contrast in color from the metal. With the KOHLER® Faucet Cleaner, you can remove stains and residue from your fixtures to leave a streak-free shine every time. 

We recommend testing your KOHLER cleaning solution on a small spot before applying to the entire fixture. Instead of allowing the Faucet Cleaner to soak once applied, wipe your surfaces clean immediately using a damp, non-abrasive cloth or sponge. Remember to thoroughly rinse your fixtures with plain water, then buff dry.

Shower Walls and Doors

As with metal fixtures, shower walls and doors can easily show soap scum. Glass shower doors also respond well to the KOHLER Faucet Cleaner when used correctly. While we typically recommend cleaning shower glass at least once a week, if not more, to prevent soap scum build-up, LuxStone® shower doors are uniquely designed to require less frequent cleaning. With CleanCoat® technology, your glass shower doors actually repel dirt and bacteria, so they stay clean for a longer amount of time.

Soap scum build-up can quickly leave fiberglass surfaces looking dull and spotted. But fiberglass shower walls and doors are less responsive to commercial cleaning products and can actually be damaged by harsh solvents. You can clean your fiberglass surfaces with a solution of baking soda and hydrogen peroxide, which should be applied and left on the surface for 15 to 30 minutes before a thorough rinsing.

Shower walls can often collect bacteria and residue along grout lines, requiring regular cleaning to prevent discoloring. LuxStone walls are grout-free, so you only have to apply the Tub & Shower Cleaner to the wall surfaces to keep them free of build-up.

Ceramic Tiles

Soap scum is easier to remove from ceramic tiles than other surfaces. Applying a commercial soap scum solution or a vinegar and water solution should take care of any stains, but you can also buff your tiles with a wet pumice stone should more difficult soap scum remain. Wet both the stone and the floor before gently working in small areas, rinsing the stone of removed scum as you work over the tile surface. Remember to avoid using a dry pumice stone—this will be too hard on your ceramic tile and can leave scratches or chips on the surface.

KOHLER LuxStone Makes Cleaning Your Shower Easier

While soap scum build-up doesn’t have to be difficult to treat, you can get the leg up on cleaning your shower with easy-to-clean LuxStone surfaces. CleanCoat glass treatment repels dirt and water from shower doors, while no-grout shower walls leave little space for build-up.
