I'm not a chemist, but I'd try some acetone (nail polish remover) first.
Available just about anywhere, and in small quantity for trial before
commuting to buy in larger quantity. To test for efficiency, I would just
pour some onto the affected area and observe the effect. You should be able
to determine its suitability that way.

I would take the approach of covering the top of the soaking can with
something like tin foil to minimize evaporation.
