- Scrub the grout lines with a grout brush or an old toothbrush.
- Rinse the area with clean water.
Vinegar and Water:
- Mix equal parts of white vinegar and water in a spray bottle.
- Spray the solution directly onto the grout lines.
- Allow it to sit for a few minutes to break down stains.
- Scrub the grout lines with a grout brush or a toothbrush.
- Rinse with clean water.
Hydrogen Peroxide:
- Wear gloves and safety goggles to protect your hands and eyes.
- Pour hydrogen peroxide directly onto the grout lines.
- Allow it to sit for 15-30 minutes.
- Scrub the grout lines with a grout brush or toothbrush.
- Rinse thoroughly with water.
Bleach (Chlorine or Oxygen-based):
- Use bleach with caution and proper ventilation.
- Mix a solution of 1 part bleach to 5 parts water.

Commercial Grout Cleaners:
- There are many grout cleaners available in the market designed to whiten and clean grout. Follow the instructions on the product label for best results.
Tips:
- Always test any cleaning solution or product on a small, inconspicuous area of grout first to ensure it doesn't cause any damage or discoloration.
- Use a grout brush or an old toothbrush with firm bristles to effectively scrub the grout lines.
- Consider sealing the grout after cleaning to help prevent future stains and discoloration.
Keep in mind that some grout stains may be stubborn and difficult to remove, especially if they have been there for a long time. In extreme cases, you might need to consider regrouting the affected areas to achieve the desired whiteness.
