It can clean grout instantly, and when mixed with baking soda, hydrogen peroxide becomes a more powerful grout cleaner with cleaning power comparable to commercial products.

In this post, we will tackle how hydrogen peroxide cleans grout, its efficiency, and some tips for how to use it around the house.

What is Grout and How to Clean It?

Before knowing how to clean grout, it’s crucial to understand what it is and where it came from. This way, you will learn other methods to remove dirt, stain, or grime. Grout is a porous material from water, sand, and cement.

You can clean grout by brushing the stained area with an old toothbrush. For a better result, you can use non-toxic cleaners like hydrogen peroxide and baking soda. Baking soda is abrasive, so it removes the dirt on grout surfaces. 

Hydrogen Peroxide, however, is a natural alternative to bleach which eliminates germs and brightens grout surfaces. It is also non-toxic and decomposes into oxygen and water.

Is It Difficult to Clean Grout with Hydrogen Peroxide?

Generally, grout is difficult to clean, regardless of the cleaner you use. So, even if you use hydrogen peroxide to clean grout, the solution may need a few minutes to work. Grout is porous, which makes it tricky to keep clean. Since the grout lines are slightly deep, more than wiping the surfaces is needed to clean them.

Cleaning grout with water alone is usually not enough. Cleaning the grout requires a cleaning agent, like hydrogen peroxide, baking soda, or toothpaste.
