Why Does Citric Acid Clean Pennies? | Sciencing

Apr 24, 2017· As the penny is placed in the citric acid solution, the citric acid cleans it in two ways. First, the citric acid is in a liquid form. This allows the dirt and grime on the penny to loosen from the metal. Second, and most importantly, the acid in the solution reacts with the copper oxide layer that has created the tarnished look of the penny.
