In the course of the last couple years I have been asked to re-terminate other cables and they have all, without exception, had some degree of corrosion in the interface between the wires and the connector. Including one set of very expensive cables (IC and SC) that specifically stated their conductor was immune to corrosion. This was true, but the interface between the conductor and connector was badly corroded. There are multiple reasons for this but all depend on the presence of oxygen so unless your cables are potted they will require maintenance to keep their performance maximized.
At least once a year, more in some climates, remove the connector body and inspect the cable and spray it with an electronics cleaner followed by Caig D100 or use D5 in one step. If you can't easily remove the connector body I'd flush the cable end with cleaner followed by Caig D5 and skip the 100 unless you can apply it directly to the connector/wire interface and any bare wire. I use the corner of a dishtowel soaked in cleaner for spots that need it, a small brush of some sort would be even easier...
All platings should be cleaned with Caig D5 or cleaner followed by D100. Unplated AC plugs need regular maintenance as well, the shiny brass fades to brown pretty quickly, which is why I like plated connectors. Many receptacles are unplated, if you're going to clean them please flip the breaker first! If you are serious about your system I would buy at least one gold or rhodium plated Furutech FPX or GTX receptacle to plug your power distribution into. See sticky thread on power for more info there.
Issues with corrosion inside components seem less frequent than with cables but it won't hurt to unplug the component and take the cover off to inspect it and dust it out once a year.
All ZenWave cables are cleaned with electronics cleaner (that is also labeled as a flux remover) followed by Caig D5 or just D5 if no soldering is involved. I am considering potting my plugs or using an enamel, varnish or PU coating, which would eliminate the need for periodic maintenance. I have always had more of a purist view because adding potting or a sealant will degrade the sound a tiny bit, so why chance it? But there is a high likelihood that a significant number of people will not do this kind of maintenance, in which case a potted cable would be best. Also, potting would change the mechanical resonance of the plug, possibly for the better, but it would be a try and see thing as to what it'll do to the sound. I don't expect a major change, most likely it'll be a smaller change in sound. Also, potting will make the connector impossible to reuse, the cable can still be re-terminated by cutting it at the base of the connector though.
EDIT: I am currently considering a Silicon coating that has similar dielectric properties as teflon and is removable. If that changes the way you would vote you are able to do so.
So, my question is would you prefer your cables to have potted connectors or no?
