[PADG:1250] Re: Ballpoint ink on microfilm

["Cybulski, Walter \(NIH/NLM\) [E]" <Cybulskw@xxxxxxxxxxxxxxxx>]

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.

Hope this helps.
