Tips for How to Clean Soap Scum From a Slate Shower

Soap scum accumulates on slate tile showers as soap lather dries on bathroom surfaces. The soap scum hardens, making it difficult to remove. A stone surface, slate tile requires a stone cleaner to remove soap scum and dirt. Using a non-stone or acid-based cleaner on the slate may result in damage to the tile surface. Clean with alkaline-based stone cleaners to remove soap scum and bring back the luster to slate tile.

Things You'll Need

  • Bath towel

  • Alkaline stone cleaner

  • Spray bottle

  • Soft-bristle brush

  • Sponge

  • Cloths

Step 1

Remove any moisture from the slate tile shower walls with a clean bath towel.

Step 2

Mix the stone cleaner with hot tap water. Pour the recommended amount of alkaline stone cleaner and hot water into a spray bottle. Read the instructions on the cleaner for exact measurements. Shake the bottle to distribute the cleaner evenly.

Step 3

Spray the cleaner generously over the slate tile. Allow the cleaner to remain on the tile for 20 minutes, or as long as recommended on the cleaner instructions.

Step 4

Scrub the cleaner gently into the tile with a soft-bristle brush. Work the brush in circular motions to dislodge soap scum.

Step 5

Wipe the cleaner and the soap scum from the slate tile with a damp sponge. Rinse the sponge with hot water and continue wiping the tile, removing all soap residue.

Step 6

Dry the tile with a clean cloth to reduce water marks on the slate surface.
