I think I posted this once before but perhaps one more time
won’t hurt too much.
We had this problem with copper plating of pieces put into the
pickler even when we KNEW for a fact that we had not put any
steel into it. We had similar discussions with customers by
phone who assured us that no steel or iron binding wire,
tweezers, etc were going into the pickle. So what was causing
the copper plating?
Turns out the plastic basket that holds the jewelry in the
pickler has a steel wire for a handle. If we filled the pickler
with enough solution or put enough parts in that the
displacement raised the level of pickling solution up to the
steel wire - well there ya go, steel being introduced into the
We contacted the vendor asked them to use a plastic handle or
copper or something other than steel. But I guess they get the
basket from another source and bottom line was they can’t do it.
We recommend you take the steel wire handle off the basket and
replace it with copper. Hope that helps.
