Another option is Simple Green. Use it undiluted, and allow the figs to soak in it. I've found that particularly harder enamels may take up to 48 hours, but once they've soaked, it's a (relatively) simple matter of scrubbing with an old toothbrush (some use one of the soft heads on a dremel, actually, but I haven't used mine for that, yet). Some will be so well softened that you can get a large amount of it off just by holding under a faucet running at relatively high pressure.
I haven't had much luck at all with Pine-Sol. Haven't used break fluid, but have been told that it will work (as will WD40, supposedly).
