how do you clean a penny with soda

by Raoul Carroll Published 3 years ago Updated 2 years ago

Simply rub the surface of each penny with a pinch of dry baking soda or alternatively, a paste of baking soda with a little water. You can use your fingers for this or an old toothbrush. Rub the baking soda all over the coins in a circular motion and then rinse them thoroughly with water.

Pour your coins into the bowl and fill with Coke. Let the coins soak in the soda for about 5 minutes, then check to see if the corrosion has washed away. If the coins still feel grimy, then you can return them to the bowl for up to 15 minutes. If left much longer than 15 minutes, the soda can dissolve the metals.
