How to Remove Soap Scum From Marble Shower Walls

Marble is the most elegant material available for shower walls and is also one of the most expensive. Since it is a natural stone, it will need to be cared for in a special way so that you don't mar the beautiful surface by using the wrong soaps. Follow these steps to remove soap scum safely.

Step 1

Put on your rubber gloves and wet your shower walls.

Step 2

Apply an acid-free soap like MB-3 Soap Film Remover (see Resources) to your marble shower walls. Dilute the soap with 2 parts water and sponge over the surface.

Step 3

Let the cleaning solution sit for about 10 minutes to allow it to break up the soap scum. You should be able to see it working.

Step 4

Scrub the surface in a circular motion to remove the soap scum. After a few minutes, you should see the clean surface of the tile when you wipe away the soap.

Step 5

Rinse the marble with warm water. If you still see areas with soap scum, reapply the soap in the same way.

Step 6

Use a squeegee to wipe the water from the shower walls to prevent the buildup of minerals. You can polish the marble with a dry microfiber cloth (do not use window cleaner) until it has a high sheen again.
