Clean Grout On Tile Floors With Hydrogen Peroxide: Best Way to Clean Grout Stains Between Tiles

Whether you have tiles on the floor in your kitchen, on the walls of a bathroom, or on the shower tiles, you can use the same methods to achieve a proper, top-notch clean. 

All you’ll need to get this job done is a cup of hydrogen peroxide, hot water, a spray bottle, and a brush. Drill brushes work wonders if you’re not using it on natural stone.

Here’s the grout cleaning process:

  1. Mix one cup of water with one cup of hydrogen peroxide and place the solution into the spray bottle. 
  2. Evenly coat the surface of the grout, ensuring that every bit of it is covered. Grout is often porous material, preventing the mixture from sliding around like soap tends to. This means that it won’t be cleaned unless the mixture is applied to every square inch.
  3. Once the vinegar mixture has stopped bubbling on the grout, scrub it down with the brush. Use gentle circular motions to prevent the grout from chipping. Take note that old grout tends to chunk apart, leaving dust and bits all over the place. If you know that the grout is several years old, try using a soft-bristle brush or a sponge.
  4. If you don’t like the smell of vinegar (although it usually goes away after an hour or so on its own), you can do a second coat of just water

Cleaning Epoxy Grout With Hydrogen Peroxide

Epoxy grout looks fantastic, but it’s usually much more challenging to clean than other types of grout. 

Since it’s somewhat porous, water soaks up and grows mold, bacteria, and other unwanted growths inside. Once they start to show up, you might find that it seems impossible to remove it. Brushing with water alone won’t dig deep within the porous surface.

Instead, you’re going to need the following materials:

  • A brush
  • 1 cup of hot water
  • 1 cup of hydrogen peroxide
  • 1 tablespoon of dish soap

Here’s the cleaning process:

  1. Mix all of the ingredients listed above in a large bottle. This might take a bit since they all have varying densities. 
  2. Once they’re thoroughly mixed, apply the solution to the epoxy grout. 
  3. Let the solution sit for 10 to 15 minutes. If it starts to dry quicker than that, you can start to scrub away with the brush. The key is to let the mixture sit to soak into the porous grout without drying it out. The cleaning process truly takes place when the solution sits since it kills off bacteria and mold. 
  4. Once you’ve scrubbed it all away, wipe it down with a rag to dry it up again. 

Note: You shouldn’t let dirty water sit for too long since it’ll start the bacterial growth again. Epoxy grout can be a real challenge, but you’ll be able to take it on without a problem using these steps.

DIY Grout Cleaner on Marble Using Hydrogen Peroxide

Getting the grout clean between marble tiles or around the exterior is easy. You only need three supplies: 

  • Warm water
  • Cup hydrogen peroxide. Mixture of cup of hydrogen peroxide with a clean cloth or microfiber cloth
  • A soft-bristle toothbrush. Don’t use anything too stiff since abrasive sponges can easily scratch the marble. The softer the brush, the better the cleaning.

Here’s the cleaning process:

  1. Start by mixing a tablespoon of baking soda into a cup of warm water. This will form a paste that’s not too far from the consistency of toothpaste. 
  2. If your mixture doesn’t create this toothpaste-like solution, continue to adjust the baking soda or water. For solutions that are too watery, add more baking soda. If it’s too thick, add a bit of water until it reaches that perfect consistency.
  3. Dip the soft bristle toothbrush into the baking soda paste and gently scrub the grout between each marble tile. Baking soda is abrasive naturally, but not enough to harm marble by any means. This is why you can get away with using a super soft toothbrush.
  4. Continue this process using circular motions until you’ve cleaned the entire surface.
  5. When you’re all finished, grab a rag soaked in warm water and wipe down the area. You might have to go over it a few times since the paste can dry rather quickly. 
  6. Dry off the grout with a separate rag to complete the cleaning process.

Tools and Machines to Clean Dirty Grout

You might be able to get away with using a sponge, a brush, or a soft-bristle toothbrush when you’re cleaning grout around the house. But why not use a tool to get the level of cleanliness that you’re looking for?

Fortunately, there are several tools that you can use to do this job. It really depends on what your budget and time frame is.

  • Scrub brush (manual hand). Scrubbing anything by hand sucks but it is cheap. So you will save money instead of needing to buy something… but it will take longer.
  • Electric scrub brush. For example, you can use a power scrubber brush. These tools look like electric toothbrushes, but they have a much higher vibration rate. These tools will dig deep into the grout without harming it.
  • Drill brush. You can also try out the drill brush mentioned above. A drill brush is a power tool that has a massive brush about the size of a kitchen sponge at the end. You’ll be able to tackle large areas in a much quicker time when compared with a normal hand brush.
  • Steam cleaners. Another useful tool is a steam cleaner. This tool uses steam to penetrate deep within the grout. It’s no secret that most bacteria can’t survive very high temperatures, which is what this cleaner has to offer. The moisture in steam loosens up dirt and grime, making it easier for you to brush away when you’re finished with it.
  • Some steam cleaners come with a scrubber at the end, allowing you to scrub the grout at the same time. While it might be a bit more costly, you’re getting the usefulness of two tools combined into one. Either way, steam is an excellent solution to old and new grout that needs a good cleaning.
  • Corner cleaners. Finally, you shouldn’t forget about corner cleaners. They’re technically not necessary, but having a tool that cuts out the grime in the corner of ceramic tiles makes everything easier for you. These corner tools also work perfectly for cleaning the grout around a toilet. There are all sorts of angles to deal with, but you can cut down the grime around a toilet in seconds with a corner cleaner.
