What’s your favorite cleaning method for connections

Deoxit. Every few months whenever I thinks about or get bored. 

Someone already mentioned Stabilant 22 .

At a cost of $50 Canadian, treating all the connections in your system with it will be the biggest upgrade you can do to your system for under $1000.  The first clean with a good cleaner then treat with Stabilant - you don't have to do it again unless you break the connection.  It has been widely tested and use in the space industry and computer industry in addition to audio. Mike Wright, the Dayton Wright electrostatic speaker designer, invented Stabilant after he sold Dayton Wright. It was tested in extremely harsh conditions and still functioned perfectly after 12 years.  We sell it at American Hi-Fi in Winnipeg Canada - Mike Wright's home town

You have a very nice system and if you don't hear any differences before and after cleaning your connectors, then making measurements is a moot point. I was just trying to warn you of potential issues with using a scrubbing pad on your connectors. By the way, this applies to all metals, not just Ag. Perhaps the degree of corrosion between your cleanings is not enough to produce an audible effect. 

I tried the rotating idea on the plugs but they wouldn't budge!  So I got a pair of channel-locks and sure enough with some great effort I got one to twist.  Actually broke it off!  Jeez no one said don't twist balanced connectors!
