Dear Christine:
Well, unfortunately, You have neither stains nor “stains”.
You simply have a hardened residue of the color enhancer sitting onto the surface of your stone.
How to remove that?
Hard to tell in a general way, because it much depends on the make of the product.
So maybe it would be best if you get hold of the customer service department of the maker of the product that was used and ask them for advice.
May I ask you now to please read and e-sign our Statement of Purpose at:

:-)
Ciao and good luck,
Mauri
