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.
