How To Clean Tile Grout (Floors)

When my family moved into our house a couple of months ago, I assumed the tile grout was supposed to be a dark, nearly black color. Then I began to notice that in some areas of the house, the tile grout was more of a light gray color. Weird, right? Why would someone use so many different shades of grout in the same house, even in the same room? {Insert a lightbulb going off in my head here} I realized that the dark colored grout was in desperate need of a good cleaning to return it to its original color!

So how does one go about cleaning tile grout? Here is what worked for me.

Things you’ll need:

  • An empty gallon milk jug (or bucket)
  • OxyClean (oxygen bleach)
  • An old toothbrush
  • A dry mop

How To Clean Tile Grout (floors) Directions:

1. Fill the gallon milk jug with warm water and one scoop of OxyClean; shake well to mix.
2. Slowly pour the water/oxy mixture onto the tile floor, making sure the mixture goes into the grout areas.

*Tip: It’s easier to clean small areas of the floor at a time. I do about 10 square feet at a time.

3. Let the water/oxy mixture sit for about 5-10 minutes, then take an old toothbrush and lightly scrub the grout.
4. Allow the water/oxy mixture to sit another 5-10 minutes and then mop floor with a dry mop to soak up the excess water.

Once your floor and tile grout has had the chance to dry, it should look better than it did before you cleaned it, especially if the grout was discolored due to dirt.

  1. Great post! The reason why OxyClean works really well is because it has oxidizing bleach, which is able to remove tough grout stains. Vinegar with baking soda is another great way to clean grout and lighten dark spots. Using an old toothbrush to scrub the grout with is okay, if the area you’re cleaning isn’t that too large. For large spaces, you would need a good grout brush, such as a triangle brush, to make the process faster and easier.

  7. Very helpful post for me! Awesome!

  8. Thanks for the tips on cleaning tile and grout. Our whole kitchen and dining room is tile, and I have never known how to best clean it. I will have to try using a toothbrush for the grout this time, and work on smaller areas!

  9. I use bleach with borax or Borateen powder to make paste, apply with toothbrush , let set a few minutes. It even removes old black gunk accumulated in crevices anywhere. 19 military moves with hubby so this got my security deposit back every time! House was cleaner than when when we moved in!
