Should a moving out roommate clean common areas?

The question isn't so much whether or not she should do it, but whether or not it's worth the hassle it might be to try to get her to, now that her mind is made up. Sure, it has to be done, but is it worth the blowup to you? Might be the easier way to just do it yourself, or pay someone to help you, than it would be to really burn the bridge over it. It's your call.
