What’s your favorite cleaning method for connections

This costs a little less than Deoxit. Make sure when using contact cleaner that it is also a lubricant,

Being a pro Bass player has taught me that the best instrument jack cleaner is a product called Flitz cleaner.

Applying it with a Q-tip and polishing it with a fiber cloth removes all built-up corrosion and oxidation.

I now use it on all of my banana plugs, spades, and even battery tips.

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.
