I believe record companies actually cleaned them with naphtha. Victor
stored them vertically in large envelopes, or so they showed in the
promo film "Command Performance"

Weren't fathers and stampers usually copper with a nickel backing?
Gun oil might work; you need something to keep the copper from turning
green, but removable so that the recording itself is accessible. I
don't remember what mothers and matrices were made from, or whether
those are susceptible to corrosion...
