Testing Two of the most popular penny cleaning methods and trying one of my own. Please note, pennies that have collector value or that remain in their original pristine mint condition, should not be cleaned with these products
The first cleaning will be with vinigar and salt, the second, with vinigar and hydrogen peroxide, and the lastly, with extra virgin olive oil.
I will be using three copper wheat pennys and one steel one, these coins carry collectors value, but they are a bit dirty so only the olive oil will be used. I will also be using some common pocket change for the other tests. Enjoy the the experience.
