Condensite is what the recording surface is made from. It is a bakelite
type resin IIRC, but not identical. The Blue amberols were indeed lubed
as well as the DD. I just do not remember what it was. I am sure that
you will need at least an EPA or Dept. of Homeland Security permit to
obtain any in todays world.

I read the Leo Bakeland came to Edison and when they tried to use Bakelite as a record coating that the record would not come out of the mold until it was thrown on the floor causing the record to break.
I have heard of people that found NOS blue amberols with a waxy coating and one guy that said DD's were given a coating for some years.

Naphtha will soften the wax. If you use enough of it you can wipe the
recording right off the cylinder.
I have seen references to the original Diamond Disks being lubed by the
factory but can not remember what was used. It was not a wax or pledge
nor was it a petroleum. The surface is basically Bakelite type resin
and is relatively tolerant of most common lubes.
Maybe someone else will remember what it was.

What book and where does it say the records were lubed?
The reason I am interested, I have recently been thinking that DD's would
likely benefit from a lube. I have written with a man that said he had used
Pledge on his wax cylinder records for 20 years with no adverse affects.
I appreciate you post because I find it interesting.
Pledge has HYDROTREATED HEAVY NAPHTHA, I have no idea how it would affect the record surfaces.
