Best practices to clean the binding posts on your speakers and amps?

Over the years, I have used both Caig Deoxit and Stabilant 22 ($).

Both clean well, and Stabilant 22 is a conductive polymer, so in theory, I have better conductance.

Good luck

 To this day I’ve never used any type of cleaner for my interconnects

or speaker cable and IME they sound fine. 👍

I’ve only cleaned terminals on used equipment and only if there is obvious corrosion or shorting. Deoxit and a microfiber cloth have been sufficient. I have used Deoxit and the “push pull” method on internal wire harnesses and cartridge/headshell pins.

Unplug and reinsert.

Kind of like never brushing your teeth---just bite into an apple and call it good
