[Icom] PW-1 SO-239 discoloration

I agree, but finding the silver plated connectors is difficult.  When left 
for awhile they look terrible.  It is usually the suphur in the air that 
reacts with the silver ware.

I am not sure about this but I think that placing the silver plated object 
in a vinigar solution in an aluminum pot and raisning the temperature to 
almost boiling will chemically change the silver compound back to elemental 
silver.  This would be better than continously removing the compound 
layer.  Check in an old kitchen aids to housewives book.
