WebJan 14, 2007 · When coins are left in your pocket for a long time, the copper in them reacts with the oxygen in the air and turns into copper oxide. That's the black gunky stuff on the outside of the coin. When you put that in an acid it will dissolve the copper oxide leaving behind just the shiny metal coin. WebTo do this, simply pour vinegar and salt into a bowl, drop in your pennies, and wait for a few minutes. The acid in the vinegar reacts with the copper in the penny, removing any dirt or grime.
