what you'll need to clean a penny
-white vinegar
-table salt
-pennies (the older the better)
-a glass container
-snacks
pour some vinegar into your glass container. I filled my container to about 0.75"
add some table salt (about a tablespoon) to your vinegar and stir
add pennies -- make sure they aren't touching and let them soak for 5 minutes.
after 5 minutes rinse your pennies and let them dry
