I've searched the archives to no avail for the answer to this
question: is it safe to clean amber-and-silver jewelry in an ionic
jewelry cleaner?
Mac, the ionic cleaners’ gentle application of voltage won’t harm the
amber on it’s own, or contribute to it in any way. What WILL harm the
amber is certain cleaning solutions you might use with the ionic
cleaner. Strongly alkaline agents, especially ammonia, will quickly
damage the amber, removing the polish. Ph neutral mild cleaners,
such as liquid dish washing detergent (palmolive, etc), probably
would be acceptable, but test it first on a small spot. The ionic
cleaner itself plays no part in this as far as the amber is
concerned. It’s all about whether the cleaning solution itself will
harm the amber. Of course, in the event you do find you’ve etched the
polish off the amber with too strong a cleaning solution, amber is
pretty easy to polish up again, so all wouldn’t be lost. But it’s a
needless extra bit of work.
