Gabi,
        I'm afraid I am not much of an expert in adhesive cleaning.  (I
don't use it very much).  But I do know that IPA will leave a film of glue
all over the board.  I have found that the particular Loctite glue we use
will come off in a saponified ultrasonic cleaner.  (Remember to use sweeping
ultrasonic if there are components on the board already!)

Thanks
