The grout in my bathrooms look horrible. I contacted a new jersey tile cleaning company and they are coming out in a few days to take a look at it. I hope they can get it to look good. We are having a few house guests in a few weeks and while I am really proud of the other areas of my home, the tile looks dingy and dirty. Even though I clean it all the time it never looks like it is clean. I would be so embarrassed to have guests use the bathrooms with the tile looking so bad.
