How to fix kitchen grout?

Is the grout coming out? Need to be replaced? Or just cleaned?

If you need to replace: you can go to your local hardware store and purchase the color grout you would like and simply go over your current grout

Re color your grout: I used this product before in one of our bathrooms and it worked great!! 6 years later no issues! it comes in lots of colors

Clean your grout: this is my favorite grout cleaner recipe: http://gatheredinthekitchen.com/category/craftsprojects/painting-staining/

What's wrong with It? Dirty, falling out???

You can remove with a grout removal tool, then put new grout in its place and seal.

Hi Eileen, hope this helps you out,
