After rereading these posts concerning corroded connectors, I think some
of us are looking at this animal from different ends.

When I said my vote is for electrical contact cleaner and dialectric
grease ... I should have said to use the dialectric grease sparingly
(not pack the connector boot).  Also, if you think you have some
connectors that are so corroded that you must use an abrasive .... I
recommend nothing more abrasive than crocus cloth.
