Seems more than a little invasive to me. I think a pass with a trusted
(read: mild)
cleaning solution in a K Monks is about as far as you want to go with
regards to
anything wet.
I'm all for doing whatever you can to secure a quiet capture; among
other reasons,
to avoid the need for excessive digital "cleaning" in post. Thinking
long-term however,
coating or spraying a disc to make it quieter at playback sounds like it
introduces more
problems than it stands to solve..

Has anyone ever found a coating or spray that can be applied to a
lacquer to make for a quieter transfer, besides water?
I seem to recall a presentation by Seth in which he mentioned Tascam
pinch roller lubricant or cleaner as a possibility.

Hi Jeff,
Just a note on Audiodisc blanks... In my experience the Audiodisc
blanks seem to have more plasticizer than some of the other blanks.
This is purely anecdotal from transfering many hundreds of these
discs.
The extra abundance of plasticizer has benefits - the recordings
tend to be quieter than other blanks, and they seem modestly less
prone to laminate shrinkage and crazing due to plasticizer loss.
The down side is that they are more prone to palmitic and stearic
acid formation than other brands of blanks. Again, this is purely
anecdotal / observation.
Per my other email, stable temperature and low humidity are more
critical for Audiodisc blanks than perhaps other brands (although
stable temps and low RH are important for storing all lacquer
discs).
Last, but not least, I would strongly recommend storing these discs
in base-buffered sleeves. The base buffer in the sleeve will help
minimize or at least stave off the autocatylitic reaction associated
with palmitic and stearic acid formation, particularly if you don't
have the driest of storage conditions.

Subject: [ARSCLIST] Lacquer disc storage conditions
I'm trying to advise a colleague who has recently discovered some
1960s-era
lacquer discs in her collection. (They're recorded on Audio Devices
Audiodiscs.) What are the preferred conditions for storing lacquer
discs?
She has access to cold storage (40 degrees F), cool storage (55
degrees F)
and obviously standard office HVAC storage.
Many thanks,
Jeff Martin
