Grout is an important element that holds tiles together and adds an aesthetic appeal to your flooring. However, it is also a notorious dirt collector and can become a breeding ground for bacteria and mildew if not cleaned regularly.

Grout cleaning can be a tedious task, but with the right tools and techniques, you can keep your tiles and grout looking brand new. In this article, we will guide you on how to clean grout on tile floors with hydrogen peroxide, a common household ingredient that can make the cleaning process a breeze.

Understanding Hydrogen Peroxide

Before we dive into the cleaning process, let us first understand what hydrogen peroxide is and how it can be beneficial in grout cleaning.

Hydrogen peroxide is a chemical compound that has powerful oxidizing properties, making it an excellent disinfectant and stain remover.

It is a colorless liquid that is widely used in the healthcare industry as a disinfectant and in the beauty industry as a hair bleach. Hydrogen peroxide is also an effective cleaning agent that can remove tough stains and dirt from surfaces, including grout on tile floors.

Materials Required

To clean grout on tile floors with hydrogen peroxide, you will need the following materials:

Hydrogen peroxide (3% concentration)

Baking soda


Spray bottle

Scrub brush

Microfiber cloth

Steps to Clean Grout on Tile Floors with Hydrogen Peroxide

Follow these simple steps to clean grout on tile floors with hydrogen peroxide:

Step 1: Prepare the Solution

Mix 1/2 cup of hydrogen peroxide with 1/2 cup of water in a spray bottle. Shake the bottle to mix the solution thoroughly.

Step 2: Apply the Solution

Spray the hydrogen peroxide solution onto the grout lines, ensuring that each line is adequately covered. Let the solution sit on the grout for about 10 minutes. The hydrogen peroxide will start to bubble and foam as it reacts with the dirt and stains.

Step 3: Scrub the Grout

Mix 1/4 cup of baking soda with enough water to form a paste. Dip a scrub brush into the paste and use it to scrub the grout lines vigorously. The baking soda will act as a gentle abrasive and help to remove the dirt and stains.

Step 4: Rinse the Grout

Use a clean microfiber cloth to wipe away the baking soda paste and hydrogen peroxide solution. Rinse the cloth frequently to ensure that you are not spreading the dirt around.

Step 5: Repeat if Necessary

If the grout is still dirty, repeat the process until you achieve the desired results.
