Ideas for cleaning up outside of cornys?

[Scalliwag]

I bought a couple of cornys that are pretty grungy on the outside, gummy crap from stickers, black scuff marks. Who here has ideas to make this cleanup task a least painful as possible?
I would feel better about these if they were clean on the outsidde as well. Is that overkill?
