    I am no expert on this subject; however, you may have encountered
    "Cosmoline" A combination of grease, shellac and beeswax with copper
    sulfate added as a corrosion inhibitor. It is initially heated and
    thinned with alcohol during the mixing state, then is allowed to
    cool and set up. If that is what the factory used; you now know the
    what it is made of ...and that might offer some clues as to what
    might be used to remove it. 

Regards, Mark
