You might contact The Disc Doctor, whose materials are used by many to clean "acetate" discs.

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.
