Oxidation, how to prevent?


I will soon move to a hot and humid area.

Can afford to run AC all day long not to mention it's not green, like your expert opinions how to prevent it?

Some of my equipments have shinny chrome faces, can I use car wax on them to prevent oxidation? What about RCA or XLR jacks? I don't think I want to use wax there since it will degrade sound, what other options do I have? I can put covers on the unused plugs, but it's not air tight and will still degrade over time.

I often read cartridge suspensions will dry up over time especially in hot weather, does humidity helps or is it worse? Will I be better off storing unused cartridges in humidity & temp control vault?

I have a spray can of Deoxit and it does help clean the cables. A good copper cleaner like Brasso also does a good job.

Question on something that has bugged me.
After cleaning the connectors, when I apply Pro Gold by using its brush applicator it seems to muffle the sound quality. I always end up wiping it off.

Are you supposed to wipe off the Pro Gold after applying it?
Actually the Caig Gold has a small amount of Deoxit and unless the contact surfaces are heavily corroded should be quite sufficient.

Elizabeth, that's a very clever way of controlling humidity. in Asia, de-humidifier is common and I will have plenty of those running to keep things dry, but wondering if heat alone will oxidize the finish.
