In this day and age, we are all looking out and after ourselves better. Many have asked us what about keys and locks? Do they have an antibacterial property or way to keep clean? Yes, there are products that be used and have been used for many years.
Copper-containing metals like brass have antibacterial properties—a selling point for brass doorknobs, locks, and other fixtures in your home. Bacteria, yeasts, and viruses are rapidly killed on metallic copper surfaces, and the term “contact killing” has been coined for this process. While the phenomenon was already known in ancient times, it is currently receiving renewed attention. This is due to the potential use of copper as an antibacterial material in health care settings.
Contact killing was observed to take place at a rate of at least 7 to 8 logs per hour, and no live microorganisms were generally recovered from copper surfaces after prolonged incubation. The antimicrobial activity of copper and copper alloys is now well established, and copper has recently been registered at the U.S. Environmental Protection Agency as the first solid antimicrobial material.
In several clinical studies, copper has been evaluated for use on touch surfaces, such as door handles, locks, and bathroom fixtures, in attempts to curb infections. Fixtures and door hardware such as brass, polished, or copper plated also carry the bacteria-fighting ability to them. We have been finding that it has made a resurgence. Many new homeowners are asking for brass handles and locks.
