You would need to use something that doesn't promote
oxidation. And since there are two dissimilar metals
touching, this is going to be difficult. Optimally,
you want something that will promote an electrical
connection.
Something like:
http://www.vandenhul.nl/other/c-care.htm
but I have seen other similar stuff at Microcenter.
It's not cheap, but worth it in the long run. Back in
my S-100 buss days, bad contacts were common. I used a
typewriter ink eraser (gee, do they make those
anymore) to burnish the contacts. The bonus is that
the eraser came with a brush. Then once the contacts
were free of contamination, I'ld coat the contacts in
contact fluid. This isolates the contacts from the air
and prevents oxidation, which happens almost
instantaneously! Now I use this fluid for all my
electrical contacts, especially low voltage
connections!
