Preserve the original condition with metadata - photos, description, etc.,
then remove the grease pencil and digitize the disc's content. I think
most would agree that recovering the audio content before the media
degrades into unplayability would outweigh preservation of the grease
pencil record of the editor's opinion, and with appropriate metadata,
both can be preserved.
In stubborn cases, I have found that a stylus actually helps break up the
grease pencil (gentle attempt at playing the disc with a non-critical
stylus), and then solvents can remove the remainder more easily. This
process did not appear to damage the lacquer or the stylus.
