stains and watermarks on slate tile

[frankief]

hi guys and gals,
Newbie to tilerforums, so Hi to everyone.
Hope you can help me, I have been asked to a property where the bathroom has slate floor tiles. The bathroom had a leak and I was able to restore the grout, but the stains and watermarks on the tiles are a pain to remove. I have tried viakal, microban, and I even tried caustic soda to no avail......have any of you any suggestions I could use to clean theses mean old tiles........:mad2:
Any thoughts would be greatly appreciated, thanks.
