Polishing Pennies

Polishing pennies was another perfect "P" activity for "P" week! We haven't polished pennies since O(5) was E's age (2), so it was time! O and I enjoyed looking at the pictures of her polishing the pennies before we began this activity.

First, E poured a half cup of white vinegar into a bowl. Then, she poured in 1 tablespoon of salt. She and O took turns stirring the mixture, and then they dropped in the pennies.

We made the mistake of leaving the pennies and other coins in the vinegar and salt solution for too long, and they turned green! Oops!


  1. WARNING!!! Pennies and vinegar make copper sulfite which is a poison that can be absorbed through the skin this is not safe yet I see it all the time please do NOT do this! Especially with old copper pennies!!

  2. Thanks for the warning, MittenMom. Is lemon juice safe to do this with?

  3. Thanks for sharing.
    There are good other option Evenspor, like baking soda and water, lemon juice and water, or also beewax polish.I am pretty sure there are some more I don't know.
    Kids love doin this, don't they?
