Why does water not shine a penny as good as cola does?
A penny gets dirty in the first place because of being exposed to oxygen in the air, causing a chemical reaction between the copper and oxygen, which forns rust. Since water is one third oxygen, and the air only contains about 10 percent of oxygen, you can assume that water makes a penny even worse. Cola is extremely acidic, so it eats away at the dirt and rust. But if you leave it too long, it will start dissolving the penny itself.
