Baking soda is a natural cleaning agent that can also be used to remove mold from tile grout. Just make a paste of baking soda and water, and then apply it to the moldy areas.

Let it sit for a few minutes, and then scrub the area clean. Rinse well and dry completely when you’re done.

According to the EPA, to effectively clean up mold, you must clean up the mold and eliminate sources of moisture.

3. Borax

Just like baking soda, borax is also an effective cleaning agent that can be used to remove mold from tile grout.

The process of using borax to remove mold is similar to using baking soda. Just make a paste of borax and water, and apply it to the affected areas. Let it sit for a few minutes before scrubbing the area clean. Rinse well with clean water and dry completely when you’re done.

4. Hydrogen Peroxide

Hydrogen peroxide is a natural disinfectant that can be used to kill mold.

To use hydrogen peroxide to remove mold, just pour it onto the affected area and let it sit for a few minutes. Scrub the area clean, and then rinse with clean water.

If you’re in the mood for some DIY, you can also make a mold-killing spray by mixing 1 part hydrogen peroxide with 2 parts water. Pour it into a spray bottle and use it as needed.

5. Vinegar

Vinegar makes a very good cleaning agent. You need to note that vinegar may not be the best cleaning agent though. It takes a little more time and effort to work.

To remove mold from tile grout using vinegar, just pour it onto the affected areas and let it sit for an hour. Scrub the area clean, and then rinse with clean water. You may need to repeat this process a few times before the mold is completely gone.

6. Bleach

Bleach is a very effective cleaning agent. However, it can also be very harsh. You need to use bleach with caution. Also note, bleach is not the recommended way to remove mold since it is caustic and odors can be dangerous to inhale.

Here are s few tips to follow when using bleach to remove mold from tile grout:

  • Wear gloves and protective clothing.

  • Dry the area completely.

Repeat this process if necessary.

  1. Fill the steamer with water.
  2. Heat the water until it boils.
  3. Hold the steamer about an inch away from the moldy tile grout and let the steam do its work for a few minutes.
  4. Scrub the area with a brush.
  5. Rinse the area with clean water.
  6. Dry the area completely.

If you don’t have a steam cleaner, you can rent one from a hardware store or a home improvement store.

Tile and Grout Cleaning Service

If you don’t want to deal with the hassle of removing mold from tile grout yourself, you can always hire a professional tile and grout cleaning service.

How To Prevent Mold in the Future

Here are a few tips to help you prevent mold from coming back:

Clean Up Spills

You need to clean up spills as soon as they happen. Mold thrives in damp and moist conditions.

If you let a spill sit, it will become the perfect breeding ground for mold. So, always remember to clean up spills right away.

Keep Things Dry

It’s important to keep things dry. After taking a shower, make sure to dry the tub and shower area completely.

If there is any moisture, wipe it up with a towel. You should also open the windows and doors to let the area air out.
