Cleaning that Harman Kardon Copper

Posted by vanmeterannie on June 16, 2020 at 12:15:07:

I have a late '50s HK Prelude that has quite a bit of discoloration (photo attached) and I've yet to find anything that will cut it. I test on the underside where there's no printing, and haven't gone near the faceplate-I don't want to risk losing what's left of the lettering so I've not really done anything remotely aggressive at all at this point since nothing seems to be cleaning it.

What do others use to make these shine again? More asking those who have actually done this and not looking for guesses since I suspect the obvious things like Brasso would remove the black ink.
