Eric,
I find that charcoal lighter fluid is a useful solvent for that sort of
gunk.  It's basically a crude form of naptha.  If your overspray is thick,
you might use a plastic scraper first, and maybe one of those sponges
wrapped with nylon mesh.  Isopropyl alcohol helps to get off the remaining
film.
