Things You Will Need
- 3 to 4 cups baking soda
- 1 cup white vinegar (optional)
- 2 to 3 cups warm water
- 1 cup hydrogen peroxide, 35 percent strength
- Sponge or microfiber cloth
- Old toothbrush
- Clean, dry cloth or squeegee
- Spray bottle
- Sprinkle baking soda on a cloth or sponge that has been dampened with either warm water or vinegar.
- Rub the sponge or cloth over both the tiles and grouting. Dampen the sponge with water or vinegar as needed, and add more baking soda to the sponge as needed.
- Rinse out the sponge and replace it with an old toothbrush for the grout-only cleaning. Rub the baking soda into the grout with the toothbrush.
- Rinse the tiled area with warm water.
- Mix baking soda and warm water in a medium plastic bowl until the mixture reaches a paste-like consistency.
- Work the baking soda mixture into the grout with the toothbrush.
- Fill a spray bottle with equal parts water and hydrogen peroxide at 35 percent strength.
- Spray the grout twice with the hydrogen peroxide formula, with an interval of at least 30 minutes between sprays.
- Leave the mixture on overnight.
- Rinse the tiled area with warm water. Wipe tiles and grout with a clean, dry cloth or squeegee.
Tips
- Borax may be substituted for baking soda.
- Baking soda is helpful for keeping shower and sink drains clog-free organically. Scoop any leftover baking soda mix into the drain, let it sit for a few minutes and run hot water into the drain.
- White vinegar may scratch ceramic tile. Use it cautiously, or substitute warm water for vinegar when scouring tiles with baking soda or borax.
