I would not attempt to wipe the image-bearing area of any silver gelatin
film with any solution.  Diazo and vesicular service copies do not have
exposed emulsions, so it might be possible to clean them.  Needless to say,
the best solution would be to avoid the whole cleaning business entirely and
have a new service copy made, or purchase one from the source if you don't
own a master.

The microphotographer in our library recommends using either alcohol or a
film cleaner (Kodak is one brand) and a cotton ball.
