The challenge I'm facing is getting it to look like it did before we grouted. We used unsanded charcoal gray grout. I've tried all of the suggested cleaners but can get the luster back. Any suggestions?
We've tried: Lemom Juice, Denatured Alcohol, stainless steel cleaner, vinegar and anything else i've seen suggested. Now I've only experimented on a few tiles at a time so as not further the problem.
Any thoughts would be appreciated.
