Does Coke Really Clean Pennies?

So many myths make their rounds in our conversations; you can jump at the last second to survive an elevator crash, or that no one can lick their elbow. But here at SMC, we are here to confirm the ultimate urban myth – coke does indeed clean pennies.

But how is this possible you may ask – how doesn’t the coke also corrode our digestive system? Carbonated (fizzy) soft drinks contain carbonic acid that is often used to remove rust and other types of corrosion from metals. Corrosion happens when the metal reacts with oxygen and the effect is different on different metals, such as rust on iron or tarnish on copper. But, the acid in fizzy drinks is weaker than the gastric acid already in your stomach which is used to break down food.

Take a look here to see it in action:

Other uses of coke are vast:

In many states (in the USA) the highway patrol carries two gallons of coke in the truck to remove blood from the highway after a car accident.
Removing grease from clothes
Basting a ham
To remove rust from car parts
To clean a toilet
