Have you tried SILCLEAR from Mapleshade?

I use Silclear and have discovered that turpintine is just the ticket to get it completly off when switching out wires. I am not totally happy with the results & have just ordered QSG as I have gold/silver alloy interconnects & just love the sound over the thin sound of silver.

I used it on tube pins and fried a circuit board on my ARC VT-100 mk2! Never again.

Using silver bearing products on tube pins, is NOT for everyone. It takes a steady hand, an ability to limit the amount applied and extreme caution. Some have no attention for detail, should completely avoid the practice and perhaps the products(altogether). They WILL cause a short, if used incorrectly, in any circuit.

Silclear from Mapleshade more or less morphed into Quicksilver Gold from Xtreme AV, the current king of contact enhancers. Cryo'd high purity silver with gold content. Cannot beat with stick.

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.
