We live in Newnan GA and have travertine and tile floors in our basement. With a the construction we've had, the grout had gotten very dirty with the clay dirt. Perfection Floor Care did an amazing job cleaning the travertine and ceramic floor. Just look at the picture. The stone and grout were the color you see on the bottom. I can't wait 'til we have them back to finish the rest of our basement.
