I've never had medical grade petroleum jelly attack any connectors....
that's not saying it won't, it's just that I've never had an issue with
it.
OTOH, I've had clear "silicone grease" attack electrical connectors such
as
"Jones plugs" and the like. The "plastic" insulation, probably Bakelite,
in those plugs would develop a dead short with only ~12V DC
across the pins in just a few months!! I say that from experience
from a late 1960's mobile radio shop. Maybe that's why I've
avoided the use of silicone *in* any connectors.
