Knownothing -
Just to be clear, and hopefully helpful, the stain is on the receptacles and plugs - not on the metal. What was on the metal was sticky gooey residue that took something like acetone or alcohol to remove. I have no idea how conductive said residue is, nor whether or not the level of conductivity changed between application and removal.
I have read but cannot substantiate (nor have the science to test) that these products are based on various kinds of vegetable oil. Some need refrigeration (why would that be) and others need to be mixed because they don't hold the metal in suspension - which makes even distribution unlikely.
Grease is in and of itself not uncommon in the electronics space - they are called electrical contact grease or similar.
Here is a really thought provoking quote on the value of things like Silclear:
Many contact greases have copper, zinc or other metals blended into a grease to increase conductivity. In a study for an aerospace company in 1985 it was concluded that putting a metal into grease DOES NOT HELP CONDUCTIVITY (caps mine). IN MANY CASES IT REDUCES CONNECTIVITY.
NO-OX-ID is an example (no affiliation, no experience)
Googling also reveals a company called Cool-Amp Conducto Lube which makes silver conductive grease for high amperage connections and is DOD approved.
There is also some stuff called Lubrimatic Electrical Contact Grease... (And a million more)
If you have been around boats (especially in saltwater), heavy equipment, aircraft or big trucks you know the kinds of environments they operate in. These greases are preventative or extend maintenance cycles. I am happy to smear them on my battery posts and 1/0 terminal rings. They work - not by improving or increasing the amperage but by maintaining the current flow at a constant level over time with less effort on my part.
IMHO gear in a rack is not subject to much but dust bunnies.
I do agree with your thinking on where this stuff would be most beneficial; though I would encourage you to jettison anything brass from your system before you start worrying about things like this...
Also, I would encourage you to read up on tinned wire which is supposed to do a lot to "smooth"out the imperfections leading to various undesirable behavior by the electrons not just at the terminals but over the entire length of the cable.
