Video Transcript Danny Lipford: If you have dark grout, like this, in order to get it looking a little cleaner and more consistent in color, this is a great solution to clean it.
Get some baking soda, mix it just in a cup. Then, at the consistency of kind of a paste, add white vinegar—just a little bit or it’ll really foam up on you. Then, mix it up like this. That’s just about perfect. Of course to do a whole floor, you’ll need a lot more than this, but just as an example here.
And then you can apply it right to the grout. Put plenty on there, you can do the whole entire floor. Then, let it sit there a little while, soak in, and start working. Then get your little brush, like this. Just brush it out. And then come back and thoroughly clean the floor. Now, like I say, it’ll make it a lot cleaner and a lot more consistent look on the darker grout.
Now, if you have lighter colored grout or white grout, you’ll want to try oxygen bleach. A lot of people use oxygen bleach for a lot of different things, but you’ll approach it a little bit differently.
Basically, you’ll take some of the oxygen bleach, and just sprinkle it over the grout joints. Then take a water bottle and spray all of the joints down to kind of activate the bleach.
Then let it sit there a little while, again come back with your brush, brush it out. Let it sit a little longer, and then wipe everything out. And that will certainly brighten up that white or lighter colored grout. And that should really make a big difference in the cleanliness and the look of your grout.
