I use a isopropanol soak. I have a half bottle that I drop it into - let it soak then shake it around and take it out.
I typically use this on computers, after thermal grease is fried on for several years its a pain to get off with anything other than isopropanol (especially because you can scrub a CPU without ruining it). It doesnt leave a residue, evaporates quickly, and cuts through any gunk without harming electrical components (assuming you let it dry!).
