I have been trying to post some responses without success. So far as I can tell, boron is relatively inert. It does not oxidize readily, therefore. The item was in a factory sealed box or package all this time. I am wondering whether due to changes in temp and humidity, the deposit comes from the plastic component of the factory container. This jibes with the fact that my friend obtained a used TK10ML along with the NOS one, and the used one has no such deposit on the cantilever/stylus.
Milky white deposit on cantilever/stylus of NOS Signet TK10ML, still in original box, etc.
A friend of mine has acquired an NOS Signet TK10ML. The cartridge was part of a huge inventory of "stuff" that he purchased from a defunct dealer. He notes that the stylus is completely obscured by a deposit of a "milky white substance". Has anyone got any idea what this could be and how to get rid of it without damaging the cantilever and/or stylus? Thanks.
I haven't examined the problem first hand, as my friend lives a few hundred miles away from my location.
