I've used ispropyl alcohol on a few such devices. I don't know if it's as effective as acetone---it did take some rubbing---but I did manage to eventually get it off, so I know that it can be used as well.
EDIT: While I've run into devices that have seen a range of this, the worst was a Grundig G6 radio. Searching, at least according to this page, it looks like the manufacturer recommends "Purple Power":

If you’ve been an SWLing Post reader for long, you’ve also no doubt read our numerous posts about cleaning off this mess. There are a number of solutions, but it seems the most positive long-term results by employing a de-greasing product called Purple Power (click here to read archived posts). Indeed, it’s the solution Eton Corporation recommends and the one I used to clean my Eton E1 XM.

Based on this, it sounds like the solvent that uses is diethylene glycol butyl ether.
EDIT2: Also on that site. Might be a good idea to look at what you're buying if you do try some:
Ron notes that “Purple Power” is not the same product or formula across the globe
We’re shared a number of posts here about how well the product “Purple Power” cleans the sticky residue off of portable radios than once had a rubberized coating (the coating breaks down over time and becomes incredibly tacky).
Many thanks to SWLing Post contributor, RonF, who writes from Australia with this important note:
Tip for non-USonians: what’s sold as “Purple Power” (and “Simple Green”, and several other frequently-recommended cleaners for this sort of thing) are not necessarily the same products around the world.
For example, in the US “Purple Power” is an ethylene glycol based cleaner/degreaser; here in Aus, if you ask for “Purple Power” you’ll get a sodium hydroxide based degreaser.
One will clean the gunk off your radio; the other will clean the gunk and most of the labelling off…
