How to Clean Tile Grout
To clean grout you can either purchase a commercially made product designed specifically for the type of grout you have or try a homemade solution using products found around the house. For more mild staining or for regular upkeep, we suggest using a simple one-part water and one-part vinegar solution. For more stubborn stains, our tried-and-true solution includes baking soda, hydrogen peroxide, and dish soap.

How to Repair Grout
If your grout is extremely dirty or is damaged, you will need to repair it. Grout repair is an easy process and a budget-friendly way to give your floor a fresh new look.
Materials Needed for Grout Repair
- Protective gloves
- Protective eye wear
- Grout cleaner
- Grout saw
- Grout float
- Clean towel
Step One: Clean the Grout
Give the grout a good cleaning using the solution and steps provided above to ensure the proper color match. This is especially important if you
don’t have any grout leftover that was originally used on the floor.
Step Two: Remove the Old Grout
Next, you will need to remove the old grout using a grout rake or saw. Be careful when using the grout rake, as you don’t want to damage the edge of the tile. Use the appropriate size rake or saw for the size of grout. Once you’ve removed all of the grout using the rake, use your vacuum to remove all the loose dust.
Step Three: Clean the Area
Use your damp sponge to thoroughly clean the area, removing any left-over grout residue. Be sure to follow the instructions specific to the type of grout you are using. With most cement-based grouts you will want to dampen the area before applying the new grout. For an epoxy-based grout, the area needs to be dry, so make sure it dries completely before applying the new grout.
Step Four: Mix the Grout
If you have a large amount of grout to apply and need more than one package, be sure to dry mix those thoroughly before adding any water, ensuring the proper color match. Mix the grout according to the manufacturer’s instructions.
Step Five: Apply the Grout
Apply the appropriate amount of grout along the grout line, depending on the size of the area, working in small sections at a time. Take your grout float and work the grout into the crevasse until it is filled completely. Once it is filled in, take a rounded stick or your fingertip and run it down
the grout line to smooth it out.
Step Six: Wipe Excess Grout from the Tile
Using a lightly dampened sponge, wipe away any remaining grout from the tile. Be careful not to use an overly wet sponge, as this will damage the grout. Allow the grout to dry for about 30 minutes. You may notice a little bit of a haze left on the tile, which can just be wiped away with a damp sponge.
Step Seven: Allow the Grout to Set
Now allow the grout to set, according to the manufacturer's instructions.
Step Eight: Apply Grout Sealer
Grout sealer is a very important step and helps to minimize the rate that moisture will penetrate the grout, making it so it doesn’t get as wet, and is able to dry more quickly. It also provides a barrier against microbes like mold.
Fully cover the grout in sealer and wipe up excess. Allow it to dry for 60 to 90 minutes before applying a second coat, and then allow it to fully
dry for about 24 hours before it encounters any kind of moisture.
This is such an easy, efficient, and budget-friendly way to refresh old, damaged, or extremely dirty grout, giving your space a brand-new feel!
