Methods of cleaning aluminum cans

How do different cleaning methods affect the microbial contamination of Coca-Cola aluminum cans?

A bacteriological study of Coca-Cola aluminum cans revealed surprising results.

The cans were tested in four states: without pretreatment, after wiping with clothes, with a cloth, and with alcohol.

Without pretreatment, numerous bacteria, including potentially pathogenic bacteria and fungi, were found on the can.

After wiping with a cloth, the microbial load was reduced, but the bacteria and fungus remained.

Cleaning with a cloth and treatment with alcohol resulted in no visible microbial growth.
