Preferred Contact Cleaner and Contact Enhancer for Audio?


I have been doing some research on the topic of contact enhancers. I've used the Stabilant 22A contact enhancer. I understand other options occur in this space, such as the Furutech Nano Liquid, the Mad Scientist Audio graphene contact enhancer, and Cardas Contact Conditioner (to name a few). Any one having experience with any of these (or others not mentioned)? And what about contact cleaners? Are any contact cleaner worth considering (beyond 70% isopropyl alcohol)?

Been through the whole gamut, A to Z, isopropyl alcohol to Cramoline, Deoxit, Kontact, Tweek, silver paste, Nanotec Nano silver/gold particles suspended in shark liver oil, silver-gold paste, even Sol Electret from PWB, cleaners and enhancers up the wazoo. Even the Total Contact Graphene contact enhancer. As I stated previously no matter what your preference is be sure and clean all non audio contacts as well as audio ones. That’s rule no. 1

Markertek sells the Caig Deoxit K-DG100L-2DB kit for $25.99 with free shipping. The kit contains both the Red and Gold cleaners, a 7.4ml bottle of each (the Red in that size sells for around $20 singly, the Gold for more, so the kit is a great value). Also included are a cleaning cloth and various swabs and bristle brushes (for tube sockets, RCA jacks, etc.). I received my order in two days, New York to Washington State!
