Any sort of light oily stuff will do.  The product called "TV Tuner
Cleaner" works on any sort of contact, is only moderately expensive
rather than ridiculously expensive, and carries a lot less hype than
Stabilant.  It may be getting scarce due to environmental laws and the
fact that most TV tuners have no contacts that require cleaning anymore.
Tuner cleaner is a solvent (in the good ol' days, it was
trichloroethylene), and a little silicone oil in an aerosol can.  Spray
it on liberally, work the connection back and forth a few times, and
contact should be much better than it was.  It's also good for
potentiometers that have developed noisy intermittent contact.
