Depends what you're going for -
For the most hassle free sale, I wouldn't move it or clean it or fix a thing - just post them "as-is" right here on Pinside. None of those things are a surprise to pin owners. Most of us aren't afraid of a game that just needs to be tweaked and cleaned, if the price reflects accordingly.
If you want to get squeeze as much $$ as you can out of them, sure, clean them up and fix them. I would not move them though, that's just me. It could sit in your kitchen for 2 months, or not work right after you move it (who hasnt been there....).
Craigslist will be mostly scammers and tire kickers, but for a local sale may be your best bet, or FAcebook or one of those other thing I'm not on.
