Dear Julia:
Why, thank you for your nice words!

As for this alleged factory dirt, I highly doubt it that it could be it: stone tiles are processed with water from beginning to end and you couldn't think of any other product as clean as stone tile off the box! Trying to guess what it is would be just that: plain guessing, and you don't need that, do you?...
The good news is that if the “dirt” disappears when wet, then a good-quality stone color enhancer like MB-6 will give you the same effect permanently.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
