All Balanced: Ghost+ recording studio XLR cables
Hmm, never used this stuff before but looks interesting. Cheap to try and no harm.
I wonder if it easy to clean the sockets themselves in situ by using something like a stiff small artist paint brush coated with this solution? (Obviously turned off at the consumer unit).
But maybe overall better to replace the sockets with new ones and go switchless? Mine must be getting on for 30 years so I guess pretty oxidised.
Added: Can't find 2 gang switchless wall sockets. Perhaps UK regs don't allow such things?

I really gotta stop reading threads like this. All it ends up doing is costing me money.

Silver oxide (Ag2O) is not a conductor, it is an insulator (resistivity 10+9 Ohm.m) and is transparent. The yellow through to black tarnishing of silver is silver sulphide (Ag2S), which is a semiconductor (resitivity 1.5-2.0 10-3 Ohm.m). These values are to be compared to that of pure silver (1.6 10-8 Ohm.m), so at best are some 105 times higher.
But it doesn't really matter because both are soft, so the action of inserting the plug into the socket will readily 'cut' through the thin surface tarnishing.
Surface smoothness is again largely irrelevent as contact is made through microscopic asperities on the surface, which even if appearing to be smooth only account for between 10 - 15% of the actual surface area.

I'm Dennis.
Covered some time ago, I use 5A round pin plugs an sockets, and duraglit to clean followed by De-Oxit.
The round holes can be done with a cotton bud, and the whole process is IMO worth it.
