    How about, stripping the plug pins and fuse holder, and putting the parts in a Ultrasonic Bath, I would think a jewellery Ultra Sonic Bath would do.

    Ultrasonic damages the surface finish, under a microscope it looks more bumpy.
    Smoother the better...and if it looks smooth to you buy a more expensive microscope.

    Seriously though, be wise about this kind of tweak, it works and its worth paying attention to...but there's a sanity level you need to heed.

    Isn't the bigger issue the Brass in the plug?

    Also the connection in the back of your gear too is probably Brass.

    If I was going to go to the lengths of cleaning pins, changing sockets etc, that's where I'd start.

    It is true that silver oxide is conductive, but the tarnish that easily develops on silver plated connectors is not silver oxide, because silver does not oxidize. Instead it is silver sulfide, brown to very dark brown (as opposed to pure black for silver oxide). Silver sulfide is not a conductor, but a semiconductor.30 Oct 2017

    Just found this. Does seem contradictory though.

    silver oxide is prepared in situ from silver nitrate and alkali hydroxide.

    It shouldn’t do - ultrasonic is far more gentle than any other cleaning method.

    Like fuses and interconnects I suppose cleaning plug pins is a controversial and subjective improvement in a systems ability but I have definitely gained some audible benefits. The gains I have achieved can best be expressed in this attached article which inspired me to do the same.
