Removing Glue

["Jones, Mark" <MJones@ngl.ca>]

I just finished removing the tinted plastic film from the back window and
two quarter windows on my GT with a razor blade scraper.  Why someone put
that crap on the windows is beyond me.  But now I am left with streaks of
glue from the plastic film.  Any suggestions as to what to use to get rid of
the residual glue.  I know xylene will work but I would rather not use a
know carcinogen.
