How to Clean Ceramic Tile Grout Stains


Grout is an important part of installing ceramic tiles; not only does it help to bond the tiles, but it also keeps moisture and dirt from getting behind the tiles. Ceramic tile grout can become dirty or stained over time. Mold, mildew, dirt and other substances can stain tile grout, making the entire tiled surface look dirty. You can clean stained grout quickly with the right products and methods.

Things You'll Need

  • Dull knife
  • Vacuum cleaner or broom
  • Empty spray bottle
  • White vinegar
  • Grout brush or old toothbrush
  • Rags
  • Plain white shaving cream
  • Scrape off any chunks of debris stuck onto the grout using a dull knife. Do this carefully so you do not chip the tile grout.

  • Sweep the entire tiled surface thoroughly to remove loose dust, dirt and debris. Use a vacuum cleaner with a soft brush attachment or a broom to sweep the surface.

  • Fill a clean, empty spray bottle with equal parts white vinegar and hot water. Shake the bottle to combine the ingredients.

  • Spray the vinegar solution onto the grout stains. Let it sit on the stains for about ten minutes.

  • Scrub the dirty grout with a grout brush or an old toothbrush. Apply more of the vinegar solution and continue scrubbing until the stains are gone.

  • Rinse the grout with a rag and plain water.

  • Squirt plain, white shaving cream onto the grout for an alternative stain removal method. Leave the shaving cream on the grout for about five minutes, scrub with a grout brush or old toothbrush and then rinse it off with a rag and water.

Tips & Warnings

  • Make a paste of hydrogen peroxide and baking soda for stains on light-colored grout. Spread the paste onto the stain and wait ten minutes before scrubbing and then rinsing. Peroxide is a bleaching agent and may change the color of colored grout.
