Hi All,
I certainly think this type of maintanence is a great idea.
Fortunately, however, cables that are connected and disconnected regularly will have a bit of a self-cleaning effect due to the friction of taking them in and out of whatever they are connecting to.
Interestingly enough, the problem of oxide build-up is more significant on permanently installed gear. If you really wanna see some crud built up, check your rca's that have been on your home stereo for a few years. Clean those suckers and it's like having a new set of cables.
De-Oxit rules!!!
Happy Recording,
Marc
