dielectric grease made for connectors..
Dielectric grease is an INSULATOR and using it INSIDE the connection surfaces will cause more problems than it fixes.
Conductive grease is much better for something like this. It looks like a paste form of graphite......because that is basically what it IS.
A careful inspection should indicate which connector is the source of the problem (gunk or corrosion evident) and that one should be replaced.
WD40 is rich in solvents and cleans pretty good BUT a lot of it should not be left in the connectors. Over a long period of time, it will start leaving a stick film with will hold dust and dirt. Flush out with alcohol or compressed air after you let it soak for a while.
