Wait!!! Before you change out those old brass doorknobs…

Brass doorknobs disinfect themselves. Several metals that are copper alloys, including brass and bronze, have antimicrobial properties (meaning they kill bacteria).

It’s called the oligodynamic effect, and it explains that the chemical makeup of these metals, even in low concentrations, have biocidal qualities.

Research suggests that when using these metals for doorknobs, push plates, tray tables, faucet handles and other equipment in hospital ICU’s reduced transmission of disease causing organisms in by as much as 58%.

Currently the CDC is clinically trialing and testing the effectiveness of this effect at 3 major U.S. Hospitals. So far the results have been positive.

So think twice before you replace those outdated brass fixtures with other metals, they are helping you more than you may realize!
