The Edison Voicewriter Discs, and probably most of the others like the
Gray and Soundscriber, and Dictabelts, are vinyl, not acetate.

Years ago, I played around with cleaning Edison Voicewriter discs (red
acetate dictation discs about the size of 45) by immersing them in
deionized water and Photo-Flo. After an hour, I gently scrubbed them
the grooves with a soft sable brush and decades old fingerprints lifted
like translucent scabs). After drying 24 hours on acid-free blotter
I was able to make a good playback pass. Not sure I'd have the gumption
try something like that today, knowing what we know now about the
of humidity on acetate.
