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.
