The cleaning formula and basic procedures used for lacquer discs at the Archives of Traditional Music are detailed in the Sound Directions publication, page 27. Available at:

I don't know that it qualifies as definitive, but it is the result of research, much experience, and consultation with Eric Jacobs.

Subject: [ARSCLIST] cleaning lacquers ("acetate") - palmitic acid deposit

there was some discussion of this a while back, but I can't find any
statement of a safe and effective way to clean "acetates" with white
(assumed to be palmitic acid).
Can someone provide a relatively safe, simple way to clean these discs?
Best wishes, Thomas.
