Cleaning tile joints can be a tedious task, especially when they are full of dirt, mold, or limescale. The good news is that with the right products and a good method, you can restore their appearance without having to scrub for hours.
A mixture based on baking soda, white vinegar, and hydrogen peroxide is very effective for most cases. These ingredients act together to loosen dirt and disinfect without damaging the surface.
Materials
- Baking soda
- White vinegar
- 3% hydrogen peroxide
- Dish detergent (optional)
- Old toothbrush or grout brush
- Spray bottle
- Microfiber cloth
- Gloves
- Warm water
Procedure
- Remove loose dirt and dust with a dry brush or vacuum.
- In a spray bottle, mix equal parts white vinegar and warm water. Add a few drops of dish detergent.
- Spray the joints generously and let it act for 5–10 minutes. The vinegar helps dissolve limescale and soap residues.
- Make a thick paste with baking soda and hydrogen peroxide.
- Apply the paste on the joints and let it act for 15–20 minutes. The hydrogen peroxide helps with disinfection and whitening.
- Gently scrub with an old toothbrush or grout brush. You do not need strong pressure – the previous soaking will have already loosened most dirt.
- Rinse thoroughly with clean water and wipe with a microfiber cloth.
- For stubborn mold, repeat the process or leave the paste on longer (up to 30 minutes).
- Dry the area well to prevent new mold from forming.
Tips and advice
- Always test the mixture on a small inconspicuous area first, especially with colored or natural stone grout.
- Wear gloves and work in a ventilated area.
- For very old or extremely dirty joints, you can use commercial grout cleaners, but the homemade method is usually sufficient.
- Prevent future dirt by wiping the joints regularly and ensuring good ventilation in the bathroom.
- Seal the grout after cleaning (every 1–2 years) to make future cleaning easier.
With this method, your tile joints will look renewed without spending hours scrubbing.
