What it means
Copper ions punch holes in bacterial membranes and interfere with the enzymes inside, so a copper or brass surface clears itself of many microbes within hours, while stainless steel and plastic do not. Copper vessels were used to keep water and treat wounds thousands of years before anybody had a germ theory to explain why it worked.
The claim comes from Royal Society of Chemistry.
