The best way to clean grout in tiles is to use a combination of bicarbonate of soda (baking soda) and distilled white vinegar, along with scrubbing. Here is a simple step-by-step method:
- Make a thick paste by mixing two parts bicarbonate of soda with one part water. Apply this paste directly onto the grout lines.
- Spray distilled white vinegar on top of the baking soda paste. The mixture will fizz and bubble, helping to lift dirt and grime from the grout.
- After the bubbling stops, use a stiff-bristled brush or an old toothbrush to scrub the grout lines thoroughly.
- Rinse the area well with water and then wipe it dry.
For heavy stains, you can repeat the process or use commercial grout cleaners. It is also helpful to check if the grout is sealed before using vinegar, as vinegar can corrode unsealed grout over time. Sealing grout after cleaning helps protect it from future staining. Additionally, for mold in grout, a mix of hydrogen peroxide and water can be sprayed on, left for 10-15 minutes, then scrubbed and rinsed. Regular maintenance includes lightly cleaning grout weekly and a deep clean every three to six months to keep grout looking fresh.
