Can You Use Hydrogen Peroxide on Grout? (Quick Answers)

Tile grout is hard to keep clean for a long time. It gets dirty slowly, and when we notice the dirt, there is a scary amount of stubborn dirt on the grout.

If you ever started cleaning the grout without proper research, you may realize the stain is tough to remove. So, what can you use for cleaning? Can you use hydrogen peroxide on grout? Keep reading to find out.

Using hydrogen peroxide on grout

Hydrogen peroxide is effective in cleaning dirty grout. 3% hydrogen peroxide is enough to clean grout. Adding other ingredients like baking soda, lemon juice, and tartar power can enhance the cleaning power of hydrogen peroxide. Generally, hydrogen peroxide is harmless.

Are you worried about cleaning your grout? Without knowing the proper steps for cleaning the grouts, you may need to keep rubbing your brush for about two days. And even then, you will not get a satisfactory result.

But let me assure you, after reading this article, you should be able to clean your grout in a couple of hours. But let’s discuss some background information to build up a clear idea about the dirty grout issue.

First, hydrogen peroxide can work fine to clean your grouts. But you can enhance its cleaning power by adding some simple household items.

Hydrogen peroxide is corrosive and is commonly used in many different cleaning and polishing products. It has also been used to clean nails and hair.

So as you can guess, it’s nontoxic but can be problematic if someone consumes or gets into contact with the eyes.

Now, let’s try to understand why grouts get dirty and why cleaning is so hard. Grouts are the stuff that fills the gap between each tile. Grout is made of sand and other molecules.

As we know, sand can absorb water very fast. So, some water gets into the grout when you clean the tiles with water. The water is often dirty floor-cleaning water.

The water evaporates, but the dirt gets stuck in the grout. That’s the primary reason the grout gets dirty, even if you clean your tiles daily.

There are many other reasons why the grout gets dirty quickly. The grout is porous and absorbs moisture. It is a good breeding ground for molds, mildews, and other bacteria.

So, even if you clean the stains from the grout, the dirty-looking stains will build up fast until you don’t remove the molds and mildews from your grouts.

This is a common issue in the bathrooms and kitchen, as those floors often come into contact with moisture quite often. And the grout stains of those places are even harder to clean.

So, why is it so hard to clean the grout? Firstly, white grout gets oxidized by the air and gets yellowish. So, without a corrosive cleaning agent, it is hard to make that white again. And the built-up dirt inside the grout makes it even harder to clean with the proper method.

We will discuss the steps in the latter part of the article. For now, check if you can clean those types of grout with hydrogen peroxide.

Tile grout:

You can clean tile grout or regular white grout with hydrogen peroxide. And after cleaning, you get a satisfying result.

Colored grout:

Is it safe?

Hydrogen peroxide is considered safe for general use but must be used cautiously. But there are many things to learn about it. But don’t worry, I will keep it simple. This knowledge may help you in different situations.

Hydrogen peroxide is H2O with added oxygen, which means H2O2. It can give away oxygen and become water. The oxidation process makes it a great disinfectant and stain remover.

The oxidation process terminates the mold, mildew, and bacteria, so the grout gets free from microbial infestation.

There are two types of hydrogen peroxide. They are 3% and 35%. 3% hydrogen peroxide is known as medical hydrogen peroxide. As it has uses in disinfection of medical equipment.

You can use medical ones to clean the household cleanings. 35% are called food-grade hydrogen peroxide. Well, you cannot eat it. It is called food grade because it is used in the food industry.

So, is it safe for humans? There are three things you need to remember. Firstly, you cannot eat it and keep it away from children and pets. Secondly, keep it away from broken skins and eyes. Once, people used it to clean wounds, but the study shows it can harm the body.

And lastly and most importantly, keep it away from fire. It is not flammable but provides oxygen to the fire, making the fire uncontrollable.

How long can you leave hydrogen peroxide on grout?

If you use 3% hydrogen peroxide and only hydrogen peroxide alone to clean grout, leave hydrogen peroxide on the grout for one hour. But if you are using 35% hydrogen peroxide, 20 minutes will be enough.

There are many commercial products to clean the grout, and many of them contain hydrogen peroxide. Hydrogen peroxide is enough to clean your grout perfectly with proper steps. Commercial products work fine, but they are a lot expensive.
