Mix a solution of 50 percent water and 50 percent natural stone cleaner in a bucket. This product is available at most home improvement centers. Check the label to ensure it is safe for travertine tile and contains a mold-killing agent.
Soak a microfiber cloth in the cleaning solution. Wring it out and scrub the travertine tile surface. Use a soft-bristle brush to clean the grout areas.
Rinse with a microfiber cloth dampened with clear water. Allow the surface 3 or 4 hours to dry.
Add a quality stone sealer to a paint sprayer. Mist a fine layer of sealant over the travertine. Allow the travertine surface 24 hours to dry.
