Hi, I'm Rachel Yatuzis and I'm going to show you how to clean grout between your floor tiles. If you make a mixture of vinegar, and baking soda, get it into a nice good paste and it's really good and abrasive, and it's really not harmful to your pets or anybody that may be walking on the floor. Use a toothbrush that you use to clean with, and scrub away. If your grout is especially dirty, or maybe there's a couple of stains, you can let the solution sit on the grout, and the vinegar and baking soda will actually pick a lot of the stains up to the surface and then you can scrub them off. And a good prevention technique, is to spray your grout with bleach water. You know, every couple of months to make sure there's no mildew or mold growing in them, in the grout. And another thing you can do is get a Clorox bleach pen, and go trace your grout with that bleach pen. That will keep it really nice and white. That's it. I'm Rachel Yatuzis. And that is how you clean grout.
