Well, I don’t think I have left anything in the pickle that
long…but I have had some gunky pieces come out.
Usually I’m still in the process of making them. I just keep on
(denial is a happy place) working and with reheating and repickling
the piece comes out clean.
So try a little gentle reheating, put in back in clean pickle and
see what happens. You might also be able to tumble it clean.
