Ultrasonic cleaning is not the complete answer for cleaning expansion bracelets. Non-expansion bracelets (I. e. chain link styles) do come out cleaner, generally. But the links on an expansion bracelet (Scissor type or ladder type) fill up with crud over years, And 15 minutes in an ultrasonic machine will not purge the accumulation. A combination of cleaning machine, brush scrub, and compressed air will do about the best clean you’ll get. And these cheap drugstore ultrasonics used to clean jewellery and false teeth are not powerful enough for bracelets.
