How to Clean Bathroom Grout: A Comprehensive Guide

Cleaning the bathroom is a task that many people dread, and one of the most challenging areas to tackle is the grouted areas. Over time, bathroom grout can become dirty and discolored due to soap scum, mold, and mildew buildup. However, with the right tools and techniques, you can effectively clean bathroom grout and restore its original shine. In this guide, we will take you step by step through the process of cleaning bathroom grout, ensuring a spotless bathroom.

1. Gather Your Supplies

Before you begin cleaning the bathroom grout, gather all the necessary supplies. This will save you time and ensure that you have everything you need to effectively clean the grout. Here’s a list of essential supplies:

  • Baking soda
  • White vinegar
  • Hydrogen peroxide
  • Spray bottle
  • Toothbrush or grout brush
  • Sponge or microfiber cloth
  • Bucket of warm water
  • Protective gloves
  • Old toothbrush or small scrub brush
  • Grout sealer (optional)

2. Prepare the Grout

Before diving into the cleaning process, it’s crucial to prepare the grout. Start by removing any loose debris or dirt from the grouted areas. You can use a toothbrush or a small scrub brush to loosen and remove any dirt or grime that has accumulated.

3. Creating a Homemade Grout Cleaner

One of the most effective and budget-friendly ways to clean bathroom grout is by using a homemade grout cleaner. Mix equal parts of baking soda and hydrogen peroxide to create a paste-like consistency. This mixture will act as a powerful and natural grout cleaner, breaking down the dirt and stains.

4. Applying the Grout Cleaner

Apply the homemade grout cleaner directly onto the grout lines using a toothbrush or a grout brush. Make sure to cover the entire grouted area evenly. Allow the cleaning mixture to sit on the grout for about 10-15 minutes. During this time, the mixture will penetrate the grout and loosen the dirt and stains.

5. Scrubbing the Grout

After the cleaning mixture has been left to sit on the grout, it’s time to scrub. Start scrubbing the grout lines using a toothbrush or a grout brush. Use firm, circular motions to dislodge the dirt and stains from the grout. Continue scrubbing until you see the grout returning to its original color.

6. Removing the Cleaning Mixture

Once you have scrubbed the grout lines thoroughly, it’s time to remove the cleaning mixture. Take a sponge or a microfiber cloth and dampen it with warm water. Wipe away the cleaning mixture from the grout lines, rinsing the sponge or cloth frequently. This step will help remove any residue and ensure a clean finish.

7. Tackling Stubborn Stains

In some cases, stubborn stains may remain even after scrubbing. If this happens, apply white vinegar directly onto the stained grout lines. Let the vinegar sit for a few minutes, and then scrub the stains with a toothbrush or a grout brush. Rinse the area with warm water to remove any vinegar residue.

8. Drying the Grout

After cleaning, it’s important to allow the grout to dry completely. A well-ventilated bathroom or the use of a fan can speed up the drying process. Ensure that the grout is completely dry before moving on to the next step.

9. Sealing the Grout (Optional)

To prevent future stains and discoloration, consider sealing the grout lines. Grout sealer acts as a protective barrier, making it easier to clean and maintain the grout. Follow the manufacturer’s instructions when applying the grout sealer and allow it to dry completely before using the bathroom.

10. Regular Maintenance

To keep your bathroom grout clean and sparkling, regular maintenance is essential. Wipe down the surfaces regularly, address any spills or stains promptly, and utilize preventative measures such as a shower squeegee to minimize soap scum buildup.

By following these ten steps, you can effectively clean your bathroom grout and achieve a pristine and hygienic bathroom. Remember to take the necessary precautions, such as wearing protective gloves, and always ventilate the area when using cleaning products. With a little effort and the right techniques, your bathroom grout will be gleaming in no time!


Cleaning bathroom grout is a task that requires some time and effort, but the result is a fresh and clean bathroom. By using the right supplies and following the step-by-step process, you can remove dirt, stains, and mold from the grout lines effectively. Remember to invest in regular maintenance to ensure long-lasting cleanliness. With a little dedication, your bathroom will be a sparkling oasis.
