De-oxit by Caig chemical has worked well for me. Much better than other means
of contact cleaning in the past.

Never use emery cloth, 1500 grit paper, regular paper, dollar bills,
business cards etc. soaked or not soaked.
The abrasive will remove the precious metal that prevents corrosion and the
paper will snag in the irregular worn contact and insulate the contacts.
If you use any of that stuff, you'll be right back fairly soon doing it
again.
Use a toothbrush or a cut off 1/4" acid brush and a 'cleaner' of some kind
sold in every single lectronic store.
Including rat shack.
Get a cleaner, NOT with any lubricant of any kind.
Use the brush while spraying to clean away all the dirt, grime and
oil-soaked grime from previous attempts. All the crud will go to the chassis
where the cleaner will evaporate in a few seconds and then you can wipe up
the crud....if you want to.
Then, use a real relay burnisher to clean up the contacts and while you are
at it, the burnisher will clean out all the paper that has got snagged on
the contacts.
Yeah, yeah.....I know....it's been done this way for more than 100 years
now.........its still wrong.
But not in this shack.
Do it right...don't come back.
Friendly and repeated rant off.
