This may be difficult especially for the grout. If the grout is bleached you may have to recolor the grout.  The framing maybe the result of a chemical reaction with the sealer and the grout, I have seen this before. I would first try honing the floor and see what that does. Than I would scrub it with a good alkaline cleaner and than rinse and repolish.

A limestone floor was recently installed

 

It was presealed with an impregnator before installation, including the edges

 

After they grouted, the grout lines still left a film on the edges of the tiles causing what looks like a one inch frame.

 

They hired a cleaning company and they came with a hydrofluoric acid which now has also bleached the grout white

 

I have to go in tomorrow to remove both the whitening and the framing.

 

I wanted your experience on this?
