Cleaning pennies is a simple but effective way to restore their shine and luster. Over time, pennies can become dull and tarnished due to exposure to the elements or from being handled. Cleaning them can help to remove dirt, grime, and oxidation, revealing the bright copper color that is characteristic of new pennies.
There are a number of different methods that can be used to clean pennies. One common method is to use a vinegar and salt solution. To do this, simply combine equal parts vinegar and salt in a bowl or container. Then, soak the pennies in the solution for a few minutes. The vinegar will help to dissolve the dirt and grime, while the salt will help to scour the surface of the pennies. Once the pennies have been soaked, rinse them off with water and dry them thoroughly.
