Copper has long been known as a natural, bacteria- and virus-inhibiting material. The cell walls and DNA of many microorganisms are destroyed on bare copper surfaces by the released copper ions. To maintain the effect, however, increased care is required, as copper surfaces age quickly and thus lose their bacterial and viral inhibiting effect. For optimal protection, we recommend polishing them regularly.

Study on the effect of copper on SARS-CoV-2 and SARS-CoV-1:
"The longest viability of both viruses was on stainless steel and plastic; the estimated median half-life of SARS-CoV-2 was approximately 5.6 hours on stainless steel and 6.8 hours on plastic."...
"On copper, no viable SARS-CoV-2 was measured after 4 hours and no viable SARS-CoV-1 was measured after 8 hours. "
