Dear Gordon:
Acetone will not remove any impregnator.
That said, your best bet is to consult with the manufacturer on the best course of action by calling their costumer service. If the product didn't seal your stone after 3 applications something is wrong. Maybe it was a bad batch; maybe it is not the right impregnator for that particular stone... No matter what, they should be the most qualified to solve your problem.
May I ask you now to please read and e-sign our Statement of Purpose at:

Ciao and good luck,
Mauri
