I use LOS as well and have never had a problem. I make sure I give
them a good wipe down with a rouge cloth and clean them with soap &
water and a quick pass under the steamer a good distance from the
nozzle. So far no problem. Some people are overly sensitive and these
people usually only wear gold or platinum.
Chris, I would not patina the ear wires since most people looking to
buy would not have seen ear wires patina’d and may object. Also I
would not want to risk a return if they did irritate the buyers
ears. Ear wires are a sensitive issue and lots of odd allergies occur
even when the metal is non allergic. I usually provide what ever the
wearer wants with out trying to convince them that what I have on
the earring will work for them.
