Dear Lindsey:
I'm not familiar at all with that product, but by the sound of it, I understand it more like a wax than a cleaner. Assuming that's a wax and that you want a cleaner, then MB-5 is an excellent product to clean polished stone surfaces.
As for the greenish darker veining, I wouldn't worry about it. They were probably there since the beginning. There's no reason that you could have mold developing on an open stone like that.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
