Cleaning Connectors
I do not have any ideas on optical connection cleaning. For other connectors I use the following products with great success and enjoyment. First, for cleaning, I use 99% alcohol or Caig Deoxit. Second, I used a metal polish either Flitz or Simichrome with a dremel tool(this can remove gold plating on connectors don't do it if you want to avoid removing the gold plating). Third, I clean off any remnants of the polish with alcohol . Finally, I apply the Quicksilver gold contact enhancer. I have tried Walkers' Extreme SST but I like the Quicksilver gold better.
I have found that this treatment practice works well with AC plugs, interconnects, speaker wire and fuse ends.
I am only interested in dramatic changes and these steps have provided a dramatic change.
YMMV
