Good question Ruchan and I, too, was watching for answers. I understand some fabricators do use it as a "preventative", but I don't know why: are they using a substandard connector material that needs the help or is there some other reason?
I did not use DeOxit on my K3 or any other rig. I haven't used as a preventative in the thousands of electronic devices I've serviced over the years including a great many in very nasty environments (salt water on large ships, etc.). One thing anyone who still uses a mechanical CW key has learned is that modern logic, using the tiniest of signaling currents, demands low-resistance contacts to work reliably. That's why I do use DeOxit on the brass contacts of my Bug. Otherwise, the rig doesn't reliably recognize the contact closure with even a small buildup of oxidation on the contacts. In theory, properly-mated electrical connectors exclude air, and so oxygen, from the mating surfaces: they pins and sockets are in intimate contact forming an air-tight shield over at least a significant part of their surfaces for as long as they are in that position. They have essentially as good a contact as if the connectors were soldered. That's exactly what the contacts on my Bug do *not* have. They spend most of the time exposed to oxidizing air. Mated connectors do not. Also, the Bug contacts bump only gently. There's no significant wiping action to remove oxidation from them. Connectors literally scrape the contact surfaces clean when they are assembled. So I keep my DeOxit handy for my manual keys and other contacts that manage to acquire a layer of oxidation that impairs their action, and I leave it out of new equipment.
