Cleaning tube pins

Anyone have any suggestions for cleaning gold plated tube pins on NOS tubes. I have heard that Caig's is not the answer. Plus, I do not want to take the chance of removing the gold plating.

Interesting. I am concerned that some of these products will leave a film that may not be compatible with the higher potential heat that a tube pin can see.

I would caution against using a wire brush.  This will leave all kinds of micro-abrasions that will permanently damage the surface.  I agree with your concern that some products may do more harm than good.  Hard to go wrong with a foam or cotton swab and pure isopropyl alcohol.
