    I get this colour change all the time and sometimes I get the silver
    turning a black/blue colour if I leave it in the ultrasonic too long,
    normal colour is restored by using a deoxadiser, Tickopur J80U is
    what I use, I also get the problem of gold doing the same thing, I
    mostly do 9ct repairs and some times after a clean in the ultrasonic
    it comes out looking like 18ct? again deoxadiser usually works. I
    have tried everything, different cleaning solutions in the tank,
    altered the cleaner to water ratio, I have even tried using bottled
    water but to no avail. Its just a problem I have come to live with
    and as a result all repairs go into the Tickopur after the
    ultrasonic. One thing I have found though, is that pieces with old
    lead/tin solder joints or gold plated findings realy discolour and
    contaminate the rest of the item, this can end up having to repolish,
    clean by hand, and tumble the item to get it back to normal.
