The Corona Key is made of brass, which is inherently antimicrobial because of its high copper content (70% copper).
Copper and brass slow or kill the spread of microorganisms including bacteria, viruses, protozoans, and fungi.
Easily clean your Corona Key and the carry pouch/sleeve with a disinfectant wipe or soap and water – it will not tarnish or corrode the brass.
The use of a copper alloy surface is a supplement to, and not a substitute for, standard infection control practices; users must continue to follow all current infection control practices, including those practices related to cleaning and disinfection of environmental surfaces. The copper alloy surface material has been shown to reduce microbial contamination, but it does not necessarily prevent cross-contamination.
