Have you tried SILCLEAR from Mapleshade?

Quicksilver is what I've been using for years and have been very satisfied. Haven't tried the Gold. Perhaps: when this container runs out. But then(I believe), if you use up a container of the stuff in less than ten years(on audio connections), you've probably applied too much.

I used the Walker Audio silver based contact enhanser for a long time and did try that by Mapleshade's product also. Goo Be Gone, which is orange based also works. But it is really Audiotop Connect 3 that think is best. This oil is the last step in Audiotop Connect Workstation that includes an acid and a base cleaner as first steps. I have found that the cleaners get nothing off gold plated contacts and so seldom bother.

Now with the High Fidelity CT-1 Ultimate cables with Stabilant 22 on them, I don't use the Audiotop on those cables.

Has anyone tried the Furutech Nano Contact Enhancer?

Kontack is all i use the other stuff dries out etc.

Quicksilver is supposed to dry out, and leave the deposit of silver behind. The container can be taped(airtight) and placed in a vacuum sealed bag, which prevents it's drying out in storage.
