Someone suggested cleaning pins of a connector inside a personal 
computer, and applying  ?dielectric grease?  to the pins before 
reassembly to prevent the connections from degrading quickly.
(There is a connector in the AT&T UNIX PC that has been observed to be
susceptible to dirty, poor connections, responsible for a ?myriad? of
problems).

Would readers please comment on this practice of preventative medicine?
What is the substance, should it be used, and where is it available?

Since I don't see this substance widely used, there must be some
negative aspects of such a practice.  I !have! seen a white grease used 
on the connections in the hostile environment of my automobile 
headlights.

Also, I have seen people spray WD40 on connectors for similar purposes.
What residues does this WD40 leave (and are they both conductive and
protective)?

If these people are misguided, what would you recommend to them for
recovering from grease-coated or WD40-sprayed connector pins?

Thank you.
Best Regards,
ruck.
