And then there's always good old IPA : Isopropyl alcohol. Fairly safe on many substances, but again, always check on a spare sample first.
Years ago, when I was employed in the I.T. industry, I used to swear by trichloroethylene as a reasonably powerful cleaner, but then it became unobtainable and was replaced by the much more volatile and less powerful trichlorotriflouroethane. Even that seems to be no longer available from the 'usual sources' now.
