Bathrooms are a common place for mold and mildew to grow. Although mildew can be removed from tiles fairly easily, it is very difficult to remove mildew from grout.
You can do it yourself by using a scrub brush and household detergent. Baking soda, vinegar, and hydrogen peroxide are all eco-friendly cleaning products you can use. You can also replace grout completely.
Here are some ways to get rid of mildew in grout.
- Use a toothbrush or a scrubber to remove the mold. A natural mold-killer product such as ammonia, baking soda and borax can be used, or you can use commercial grout cleaners.
- Make a paste of half water and half baking soda to clean grout. Allow it to sit for 10 minutes, or up to 2 hours if you have very dirty grout. Then spray the grout with water. Finally, scrub it and rinse it.
- To remove mildew stains from grout, you can use oxygen bleach, chlorine bleach, or hydrogen peroxide. Spray the grout with the solution, let it sit for a few minutes, then wait. Re-apply the solution if it doesn’t work. Rinse with water if necessary. To increase efficiency, you can stick bleach-soaked paper towels to grout. The stains should be gone by the next day.
- You can replace grout if nothing else works. You can use a flat screwdriver or a scraper to remove the grout and then apply the grout.
- You can reduce humidity in your bathroom to prevent mold and mildew growth. After you have finished showering, open a window and use a humidifier. After you have finished showering, spray equal amounts of vinegar and water on the grout.
