Should I keep this tile floor?
We are doing a facelift of the only bathroom in our house. The tile floor (from 1955) seems to be in fairly decent shape, but try as I might, I cannot get it as clean as I'd like. Plus, the grout lines are nasty-dirty. Is it possible to clean/restore this tile to its original state? Are there companies that do this kind of work, and if so, what type of company should I be looking for?
Thanks in advance for your help!
