If mildew steaks are present on some of the ceramic tiles and grout that that form the interior walls of your bathroom's shower stall, remove them with the following steps. Once the shower stall walls are mildew-free, some simple steps can be completed to prevent mildew from forming again.


  • baking soda
  • white vinegar
  • bowl
  • spoon
  • sponge
  • tile brush
  • grout cleaning tool
  • thin scrub brush (with natural bristles)
  • water
  • towels
  • fan
  • spray bottle

Make A Cleaning Paste And Apply It To The Mildew Stains

Add equal amounts of baking soda and white vinegar to a bowl. Stir the ingredients until they are combined and have the consistency of paste. The natural ingredients will effectively eliminate mildew without damaging the tiles or grout. Apply a thick layer of the paste to the grout with a sponge and wait a few minutes for it to penetrate the stains. Use a tile brush to loosen the grout.

Apply moderate force when pressing down on the brush's handle and move the tool briskly back and forth. Use a grout cleaning tool to scrub the joints in between the tiles. If you do not own a grout cleaning tool, use a thin scrub brush with natural bristles to clean the grout. Apply more of the cleaning paste as needed until all of the mildew has been eliminated from the shower's interior walls.

Rinse And Dry The Tiles And Joints And Prevent Mildew Growth

Rinse the tile walls with warm water and dry them with towels. Make sure that the walls are dried completely, since mildew thrives in moist, humid locations. To prevent mildew growth in the future, keep the bathroom well-ventilated. While you are showering, open a window or turn on a fan. If there isn't a fan already in the bathroom, set up a portable one in a dry area. Once you have finished using the shower, dry off any wet or damp surfaces in the bathroom with a towel.

To further protect the tiles and grout from mildew growth and keep the shower's walls clean, make a cleaning solution by adding equal parts of vinegar and water to a spray bottle. Shake the bottles contents until they are blended. Occasionally spray the cleaning solution on the shower's interior walls. Wipe the walls down well before rinsing them and drying them. The cleaning solution will eliminate grime and dirty residue that can contribute to a breeding zone for mildew.

By continuing to keep the shower stall clean and dry on a consistent basis, mildew stains will not become an issue again. Contact a professional, like All American Stone & Tile Care Inc., for more help.
