I have some granite rough cut stairs that have a yellow shade on about
75% of the stone that I could use some thoughts on how to remove the
yellow. I have tested some good cleaners and some sealer remover with
not a lot of luck. I am going to use GPC tomorrow and thought I would
ask if anyone has ran into this and had some other thoughts for when we
are there tomorrow. The granite is white in color with black grain.
