- 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.
