I think acetone will soften poly, but won't remove it. At least, that was my experience last week, and it seems to be confirmed on the web.

Acetone is commonly recommended for removing finishes, but it can damage the wood. I prefer to use a finish remove (citrastrip or something like it) to remove a finish. I do soak in acetone if a stock has a lot of oil deep in it.

But to answer the OP's second question, I do not believe polyurethane penetrates the wood like an oil finish does. Polys are surface only, so if you sand them off the surface, you've gotten all of it.
