Default Re: Audiophoolery?

That is what I do too. Tarnish is bad. The only thing to make sure is that all traces of the brasso are gone. An alternative is green scouring pads to break up the tarnish, with a wipe over with IPA to get rid of the dust.

Of course the same thing happens inside the socket too, but a spot of contact cleaner on the now clean mains pins and then push it in and out a few times is all that is needed.

I've also found that older MK mains plugs (particularly the rubber ones) had silver plated fuse clips inside, which get thick black tarnish. I usually just dump those and put on a new plug.
