DIY Grout Cleaner: Transforming Your Tiles with Baking Soda and Hydrogen Peroxide

Grout, the often-overlooked space between your tiles, can easily become a breeding ground for dirt, grime, and mildew. But fear not! There's a simple and effective solution that can help you restore the brilliance of your tiled surfaces - a DIY grout cleaner made from baking soda and hydrogen peroxide. In this blog post, we'll guide you through the process of creating and using this powerful, non-toxic grout cleaner, helping you achieve sparkling clean grout lines without the need for harsh chemicals.

If you've visited me here at Lia Rose Simply Home previously, you're familiar with my passion for all-natural DIY cleaning solutions. I must admit, I had some reservations about the effectiveness of baking soda and peroxide to clean the grout in my kitchen and bathroom. However, I can confidently say that this DIY grout cleaner truly does the job. Take a look at the before and after photo above showcasing my bathroom floor grout, with minimal scrubbing.

When we embarked on the kitchen and bath remodeling journey a few years ago, I found myself torn between ceramic tile and laminate flooring. In the end, I opted for ceramic tile due to its durability, a choice seemingly well-suited for our bustling kitchen. Little did I know the challenge that lay ahead in keeping the grout clean.

Why Baking Soda and Hydrogen Peroxide?

Baking soda, or sodium bicarbonate, is a versatile household staple known for its cleaning properties. Its gentle abrasiveness helps to scrub away stains and dirt without scratching surfaces. Hydrogen peroxide, a mild antiseptic and disinfectant, has excellent stain-removing abilities and can also help eliminate mold and mildew.

This DIY grout cleaner, crafted from a blend of baking soda and peroxide, proves its effectiveness beyond just floors. It effortlessly rejuvenates grout in both shower and countertop settings. Surprisingly, tile countertops still exist in many places!


- ½ cup of baking soda

- ¼ cup of hydrogen peroxide

- 1 teaspoon of dish soap (optional)

- A bowl and a spoon for mixing

- An old toothbrush or grout brush

- Clean, dry cloth or paper towels


1. Prepare the Mixture: In a bowl, combine the baking soda and hydrogen peroxide to form a paste. If desired, add a teaspoon of dish soap to enhance the cleaning power of the mixture. Stir until you achieve a smooth consistency.

2. Prep the Area: Before applying the mixture, ensure the grout lines are free from loose dirt and debris. You can use a vacuum or a broom to clean the area.

3. Apply the Cleaner: Using an old toothbrush or a grout brush, apply the baking soda and hydrogen peroxide mixture onto the grout lines.

Work in small sections to prevent the mixture from drying out.

4. Scrub and Wait: Gently scrub the mixture into the grout lines using circular motions. Focus on areas with heavy staining or discoloration. Once applied, allow the mixture to sit for about 10-15 minutes. This gives the ingredients time to work their magic.

5. Scrub Again: After the waiting period, return to the first section and scrub the grout lines once more. You may notice that the mixture has become discolored as it lifts dirt and stains from the grout.

6. Rinse and Dry: Use a damp cloth or sponge to wipe away the cleaning mixture. Rinse the area thoroughly to remove any residue. Finally, dry the tiles and grout lines with a clean cloth or paper towels.

Tips and Precautions

- Test a small, inconspicuous area before applying the mixture to the entire grout surface.

- Avoid using this mixture on colored grout, as the baking soda's abrasiveness could affect the color.

- Open windows or ensure proper ventilation when working with hydrogen peroxide, as it can release oxygen and cause mild fumes.

- For stubborn stains, you may need to repeat the cleaning process or consider a professional cleaning solution.

With just a few simple ingredients, you can create a powerful and environmentally-friendly grout cleaner that revitalizes your tiled surfaces. Baking soda and hydrogen peroxide work together to lift stains, eliminate mold and mildew, and leave your grout looking as good as new. So, roll up your sleeves, grab your DIY cleaner, and watch your tiles transform before your eyes!
