Hello Amp Fans:
The tarnish which you wish to clean is actually silver sulfide, not silver
oxide. Silver is a wonderful getter for sulfur ions. Silver has the
wonderful property of only oxidizing at temperatures above 200 degrees
centigrade, and I doubt that your equipment has seen such temperatures.
The sulfidated surface can be easily reduced by a dilute solution of water
and HCL, might be about 5% by volume, more or less. It then can be rinsed
off following brightening. The solution should totally restore the original
luster of the silver plating.
73 and Happy DXing,
Mike
