Hi Tom,

There was an excellent ARSC presentation in 2014 (Chapel Hill)
by Eric Breitung of LoC about Cleaning Solutions for Heavily 
Degraded Lacquer Discs.  This may be the presentation Steve 
is thinking of. But its focus is specifically about cleaning lacquer.

Video of it can be viewed at the ARSC site by ARSC members.
