Copper eliminates germs on contact

It’s cold and flu season, and you can’t be too careful about the spread of germs. Have you ever wondered who touched that doorknob before you?

When someone with a cold or the flu sneezes or coughs into his hand and then opens a door, the next person to touch that doorknob runs the risk of becoming infected. Cross-contamination of bacteria and viruses is one of the leading ways illnesses are spread. Frequent hand washing is one way to avoid the transmission of germs; another is to make the surfaces self-cleaning.

Studies being conducted at the University of Southampton in the United Kingdom are proving that copper and its alloys, brass and bronze, effectively eliminate bacteria and viruses that cause illness.

The research has also shown that stainless steel, aluminium and plastic touch surfaces do nothing to help eradicate germs. Once contaminated, a stainless steel doorknob, faucet or handrail can harbour bacteria and viruses until it is disinfected, usually with harsh chemicals.
