@whodatdair Not an archaeologist, but I wouldn't add any chemicals if your goal is to conserve it in its current state. You might just touch it less, not bang it around, keep it dry and in a container, that sort of thing.

@[email protected] Thanks for this explanation. Your conclusions map pretty well onto the choice of monaural or stereo cartridges for playing 78s: the “proper” solution (e.g. Denon DL-102) is expensive and obtains only a very marginal benefit.
