Hi Phil etc,
I've been using 3M dielectric grease on all outside (weather exposed) connectors (solar panels) and light bulb sockets since I was knee-high to a grasshopper (after seeing it used on automotive/boating connectors). What would be a good lubricant for charging connectors if dielectric grease is not? Occasionally EV charging ports wear out over time (saw one last week on a Chevy Spark, poor connection). I assume it's then not a good idea for connectors that are pulled apart frequently that can attract dirt. Is WD-40 better? Have a renewable energy day, Mark Mark E.

I'll stand by my recommendation that people should buy a hardwired Tesla wall-connector for daily use instead of making due with the less robust mobile connector.
