Try some vegetable oil. Put some on a spot. Let it sit for 15 minutes and rub it with a soaked rag. See if it starts to come off.

I'm not joking. There was a big thread last year and several folks said this was effective (as well as the WD40 speeder mentions)

You have to have a residue on it though or it chewed into the paint a bit and could be removed out of the depressions like the last two pics?

No more sanding for a little bit, please.
