If you unintentionally copper coated your silver jewelry by sticking steel into the pickle, here’s how to remove it.
Remove the item from the pickle, neutralize it with baking soda and rinse.
Instructions to remove copper flashing:
Mix 50% drugstore variety hydrogen peroxide (available in 3.5% – 6% concentrations) and 50% pickle from your pickle pot.
Clear plastic disposable medicine cups work nicely for measuring.
Insert copper plated piece into the mixture.
Wait a minute or two.
The pickle/peroxide mix can be reused. After a few hours (I leave mine to sit overnight) the hydrogen peroxide will no longer be active.
