Clean a travertine shower by filling a bucket with a gallon of warm water and adding a few drops of mild dishwashing detergent. Apply the solution with a rag or sponge, and rinse with clear water. Avoid using acidic cleaners, including vinegar on travertine, which is limestone hardened by moving water. Acids dissolve the stone and can cause permanent etching.
If the shower is especially dirty, use an alkaline tile cleaner to remove the buildup. Follow the manufacturer’s directions for mixing the cleaner with water, and pour it into a spray bottle for application. Spray the cleaner on the tiles, and scrub them with a stiff scrub brush. After it sits for 20 minutes, scrub the shower with the brush again, rinse the cleaner away, and dry the surface with a towel.
Prevent stains on the shower from the minerals in the water supply by wiping the surfaces with a squeegee after each use. After the surface of the tiles dries, polish it using a soft cloth.
Travertine is a natural stone that is durable and long-lasting with proper care. It has a dense, porous surface with a rough texture that is more difficult to clean than many other natural stone products.
