If it is electrolytic nickel and flash gold we do not expect any tarnish in stored condition for at least 2 yrs.

  Greetings Mighty Techneters.
   
  Under normal environmental conditions, (As in no special effort is being made to create and maintian a particular controlled environment) how long will it take for Gold (gold fingers) to tarnish or show evidence of oxidation?
   
  I am not considering any extremes in temperature and or humidiy.  Just on a shelf at an assembly house.
   
  I know how to clean them up, but someone asked me and I didn't have any range of responses to offer.
   
   
  Thank you,
   
   
  Steve M.
