If you have tile floors in your house, chances are you deal with dirty grout. Perhaps those white grout lines have turned brown; or almost black. Not to worry, there is an easy way to whiten grout, and you only need two ingredients: baking soda and hydrogen peroxide. This tutorial will walk you through how to clean grout with a DIY grout cleaner.
I have made a lot of cleaning recipes over the years, and I can honestly say this DIY Grout Cleaner is one of my favorites. The results are truly incredible! I am not kidding when I say it works like magic. My grout went from dirty brown to “like new” status with just a little scrubbing.

Ingredients Needed for Homemade Grout Cleaner
- Baking Soda– Baking soda has the ability to pull dirt and grime out of so many surfaces (check out how well it worked to clean a greasy, grime-y oven door!)
- Hydrogen Peroxide– The wonderful thing about hydrogen peroxide is it not only works with the baking soda to clean grout, it is also a disinfectant.
The mixture of hydrogen peroxide and baking soda works to whiten and brighten dirty grout. It also works to clean a porcelain sink!
Supplies Needed to Clean Grout
- Toothbrush– Or you can get fancy and use a grout cleaning brush; or get even fancier and use an electrical scrub brush made for cleaning grout
How to Make Grout Cleaner
Start by adding baking soda to a bowl. The amount you add will depend on how much grout you need to clean. I started with a 1/2 cup, which may be enough for a small entry area. If you are cleaning grout in a bathroom (or another larger area), you will need more than that.
Remember, you can always make more grout cleaner if you run out, so go with a smaller amount to start.
Now stir in some hydrogen peroxide until you get a pasty consistency. Start by dribbling in a little hydrogen peroxide; then stir. Add a little more. Stir. If you accidentally add too much, just stir in a bit more baking soda.
How to Clean Grout
Prior to using any cleaning product, it is highly recommended that you test the solution on a small area to make sure there is no undesired change to your finish. For more, please see our disclaimer statement.
I have found it easier to work in small sections of the floor so you can keep track of where you have cleaned and not end up with the grout cleaner mixture all over the place.
Start by scooping up a bit of the DIY Grout Cleaner onto your brush and simply start scrubbing your grout. You will see a change almost immediately!
After scrubbing a section of grout, go over it with a wet sponge to remove the excess grout cleaner. Then repeat the process in the next section.
When you are finished cleaning the grout, I would recommend using our DIY Floor Cleaner to wash the floor to remove any baking soda residue that remains on the tiles.

Common Questions About How to Clean Grout & DIY Grout Cleaner
Does This Grout Cleaner Damage Grout or Tiles?
While this DIY Grout Cleaner shouldn’t damage your grout or tiles, I always recommend testing a small “out of sight” area to make sure there is no unwanted change to your surface. I have read mixed reviews about using hydrogen peroxide on dark or polished marble, so if that is what you are working near, it would be very wise to test before using this recipe.
Can I Use Bleach to Whiten Grout?
Do not use bleach to clean grout. Bleach can damage and discolor both grout and tile over time.
Will This DIY Grout Cleaner Work on Really Dirty Grout?
Yes! I am not a scientist, so I don’t know exactly how this DIY Grout Cleaner pulls out dirt, but I can say it definitely works on really dirty grout.
Can I Make A Larger Batch & Store It?
No. This needs to be made and used right away. Hydrogen peroxide loses its effectiveness when exposed to light for too long (which is why it’s stored in a dark bottle). Not only that, I once tried making my DIY Stain Remover with a natural dish soap that contained baking soda; because I mixed that dish soap with hydrogen peroxide, the bottle pressurized and all my stain remover leaked out. Another reason not to store this.
DIY Grout Cleaner
- Baking Soda
- Hydrogen Peroxide
- Toothbrush or Grout Brush
- Start by adding baking soda to a bowl. The amount will depend on how much grout you have to clean. For a small entry, start with about 1/2 cup. For a larger bathroom floor, try a full cup. (Remember, you can always mix up more if needed)
- Add hydrogen peroxide to the baking soda and stir. I recommend adding a few squirts of hydrogen peroxide, then stir. Add a bit more. Stir. Repeat this until you get a consistency that resembles soft toothpaste. You want it to stay on the brush and not drip off. If you ever feel the consistency isn't right, you can always add more baking soda if it's runny or more hydrogen peroxide if it's too dry.
- To use, scoop up the mixture with a toothbrush (or grout cleaning brush) and scrub onto the grout lines.
- Wipe excess with a wet sponge.
