Yes. I have a Microsoft flight simulator controller that was covered with this stuff. I tried a lot of things and a wet rag then dipped in acetone worked best.

I have several examples of phones, mp3 players, etc that are so far gone that they feel just plain icky. The only non-acetone removal process that works for me is to rub it off with my finger. It's not optimal. Products like Windex or Crud Cutter make it worse.
