Remove Mildew From Travertine Tiles In A Shower Stall And Protect Them With Sealer

If mildew is on the surface of the travertine tiles in your shower stall, learn how to remove it with the following steps. After the tiles are clean, apply a coat of sealer over them to prevent mildew from forming in the future.

Use The Following Items

  • commercial stone cleaner
  • vinegar
  • spray bottle
  • soft scrub brush
  • water
  • squeegee
  • soft cloths
  • natural stone sealer (water based)
  • buffing cloth

​Remove The Mildew

Clean the travertine tiles with a commercial stone cleaner and a soft scrub brush. Leave the cleaning agent on the areas that contain mildew for several minutes until it penetrates the stone surface. Move the scrub brush around in circular motions to loosen and remove the mildew. Do not apply too much pressure to the scrub brush because it can damage the travertine tiles.

If you have difficulty removing any of the mildew stains, apply a small amount of vinegar to them with a spray bottle and move a soft cloth over each area. After all of the mildew has been eliminated, rinse the tiles off with warm water until no residue is left on them. Use a squeegee to remove excess water from each tile's surface. Dry the tiles off with a soft cloth.

Seal The Tiles

Travertine tiles are porous, causing them to stain easily. If you apply sealer over them, it will prevent damage and staining in the future. Pour a small amount of natural stone sealer that is water based to a buffing cloth. Wipe the sealer evenly onto the tiles, moving the cloth across the surface in straight lines. If any of the sealer drips across the travertine surface, wipe it away with a different cloth.

Wait for the sealer to dry completely. This may take a couple hours. You can speed up the drying process by leaving the bathroom windows open so that fresh air blows inside. Add a second coat of sealer with the same steps and wait for the tiles to dry completely before turning the water on inside of the shower stall.

Maintain The Tiles

Surface stains will be easy to remove from the tiles once they are sealed. Wipe the tiles off regularly with a soft cloth that has a small amount of stone cleaner applied to it. Dry the tiles off after showering with a soft towel. Add a couple more coats of stone sealer to the tiles each year to keep the travertine protected.
