As part of an offline discussion, I looked up the polymerization time for orange oil and lemon oil, as well as the mineral oil base.
Turns out it takes weeks to months for the natural oils to polymerize, and even longer for the refined petroleum oils. It is the thin surface coat which gives a sheen to the underlying finish and thereby "improves" the appearance. Yet that thin oil layer immediately begins binding to dust and other particulates, as oil will do, and slowly polymerizes (crosslinked molecules binding to each other) into a sticky mess, and this is what dulls the shine.
A lot of the reliance on wax and oil dates back to a time when finishes were, in a word, dreadful. Make that "simply dreadful", which is two words. Shellac was fragile and the only alternative was multiple coats of a drying oil, such as linseed oil. While George Grotz can be entertaining, he wrote in an era where even the best of finishes readily degraded. Waxes and oils should remain in the Eisenhower era where these best belong.
Modern urethane and petroleum varnishes are wonderful finishes by comparison, and these do not need the constant oiling and waxing required to maintain their ancestors.
