Ketchup contains vinegar, a weak acid, which breaks down the copper oxide on the surface of the penny. The salt in the ketchup goes on to add dissolved chloride ions to the mix. These ions bond with the copper, forming copper chloride. The copper chloride helps the vinegar further break down the copper oxide.
Can ketchup clean pennies?
Soak your pennies in ketchup to clean them like new. Well, after you wash the ketchup off, that is. The salt and acetic acid in vinegar do the trick. Hot sauce, like Tabasco or taco sauce, also will remove the oxides off pennies.

This is why most pennies you see look dirty or tarnished—it’s not actually dirt but copper oxide that makes them look so dull.

The copper of a penny, for example, is made up of copper atoms. But sometimes atoms of different kinds join to make molecules. Copper atoms can combine with oxygen atoms from the air to make a molecule called copper oxide. The pennies looked dull and dirty because they were covered with copper oxide.
Why coins lose their shine?
As the pennies circulate, they begin to lose their shine. This is largely due to the way metals react with air. As the metal continues to react with the air, it develops a coat of copper oxide around the outer layer of the coin.
