It does not seem to matter which kind of tile you use in the toilet, soap scum can still build up on it. While stone tiles bring an earthy and calming feel to your bathroom decor, when it is covered with soap scum it is difficult to enjoy a hot relaxing shower. While acid-based cleaners efficiently strip soap scum from porcelain and ceramic tiles, vinegar, vinegar and abrasive cleaners can damage delicate, porous stone. A cleaner using a neutral pH allows you to wash stone shower tiles without causing etching or dulling.
Spray the shower with stone cleansers or non-acidic soap scum cleaner.
Cover the whole shower using the cleanser and allow it to sit for 15 minutes.
Wipe the walls clean using a damp sponge, rinsing and wringing from the sponge frequently until the soap scum is gone.
Scrub limestone mosaic-tile flooring using a nylon-bristle scrub brush, since these tiles can take a more aggressive cleaning.
Dry the shower using a squeegee or chamois fabric.
Seal the shower using a penetrating stone sealer according to the package directions. The penetrating sealer protects the limestone against damage and seals the esophagus as well.
