and also the build up of crystallization fluid will yellow in the grout lines..See it all the time. If you havent seen my interview about crystailization you may want to check it out at http://youtu.be/iNrCODk8Ais
that is very common with crystalized floors. i think it has to do with the steel wool rubbing the grout, you will also see it on terrazzo where it his the metal strip.
