Terrazzo Excel Master Floor Care 20 Jul 2010 21:56 EDT

Working on a Terrazzo floor.  Carpet was glued down on it for about 30 years.  It has been ground with 30 grit - 400 grit.  When it dries the yellow from the carpet adhesive is visible.  Any suggestions on how to remove the yellowing?

Thank you,
