Grout lines between tiles are exposed to dirt, moisture, and wear. If they aren't cleaned and maintained properly, they can become breeding grounds for mold and bacteria. Here's what you need to do to keep them clean and in good condition.

1. Regular Cleaning To prevent dirt buildup, wipe down the grout lines weekly. Use an old toothbrush and a solution of water with vinegar or baking soda. Scrub gently and rinse with clean water.

If the grout lines are very dirty, you can use a specialized cleaning product. Apply it, let it sit for a few minutes, then scrub and rinse thoroughly.

2. Protecting Grout from Mold Mold appears in damp areas, such as the bathroom or kitchen. To prevent this, ensure good ventilation. After showering, wipe away moisture from the grout lines with a dry cloth.

If you notice black spots, clean them immediately with a solution of water and bleach. You can also use special antifungal products.
