How about silver polish - is that any good for this?
Someone told me it is - but I don't know.

Hi OM,

If silver polish worked, then you could as easily boil it in water in
an aluminum pan - does the same thing.

You could also use a typing eraser to clean the mating surface. This
is an old board cleaning tip that was NASA approved back when there
were typewriters to need typing erasers. These erasers had the right
amount of abrasive without having too much. The same goes for a
dollar bill having just enough abrasive (useful for cleaning fouled
relay contacts). But none of this really takes care of the problem.
It simply puts you into the lock-step of a chemical dependency.

This all returns to the same lack of need when tightening up the
contact spring would do the trick just as Mark described. The "good"
chemicals that have been suggested are not cheap, and the "bad"
chemicals (Hydrochloric Acid no less) are extremely cheap to get, but
a pain to get rid of.
