What’s your favorite cleaning method for connections

Lots of things to try! Thanks! Now I’m trying to figure out what to use to lube plastic transport drawer parts with. Non- petroleum based for sure. Lithium grease is popular but it congeals over time and has petroleum so I guess silicon based grease will be it. Any suggestions?

I french-kiss it. Make sure to unplug everything first, and also brush thoroughly beforehand. Good lick.

Oops. Good luck.

Deoxit and a little friction. Slight twists while reinserting. 

I like an Australian kiss personally!
