> Subject: [sccpartners] Grout mess in marble shower Hi,
> Have a client who just had their shower installed with marble/limestone subway tiles (2"-3" tiles)and the installer left grout residue all over the tiles on the floor and walls.  My approach on ceramic tile is usually to use an acid cleaner and some elbow grease, but in this case was thinking that I would hone with a honing powder or monkey pad (or combination of the two) and then polish back up. Does this seem the way to go?  If so, I would guess that 250 or 400 grit would be appropriate.  Thanks,
