Dielectric grease doesn't conduct electricity and probably shouldn't be used on electrical plugs. I suggest using a conductive grease such as Noalox which is inexpensive and can be picked up at any Big Box store. Hope this helps.
Conductive grease sounds like a really bad idea to me for electrical plugs. If any grease bridged between the plug's pins, you'd have current leaking through it and heating things up.
The act of inserting the plug into the socket serves to move dielectric grease from the actual points of contact in practice, so the electrical conductivity of the connection isn't noticeably impaired in practice. Its purpose is mainly to prevent corrosion on the rest of the contacts--which is sometimes valuable, but won't do anything useful to correct sockets that are loose or pitted or already corroded, which is likely the problem here.
