The main reason wax is recommended over oil is due to the fact that oil attracts and holds on to dust. Dust holds moisture and moisture leads to rust. Wax will not hold the dust and therefore that problem is eliminated.

Typically, the museum pieces are like safe queens and do not get handled often, so Patrick raises a valid point. I still believe that wax prevents fingerprints whereas oil does not. There are corrosive salts in persperation that the wax will repel where the oil will not.

Like most things in life, to each his own. I have used both oil and wax and for long term storage in my room, the wax seems to hold up better.
