epifluorescence and granite tiles

Posted by Harvey on March 12th, 2002 12:05 PM

I grouted my polished granite floor tiles and used hard water in the grout. Now my gray grout is white. I was told it was due to the high mineral content and needed to do an acid wash.

My question is what will the acid do to my polished tile? Will it etch it?
