Wine stain

Hello Again,

Is there a way to pull out red wine stain from Bianco antique? Have a lady who's Stone (http://g603.net) was put in by another fabricator years ago....not sure if it was sealed to start with, I assume it was, but it should of been maintained regularly since.....It is not a dark stain just some pinky dots.

Anyone?????
