 We all heard that the deadly coronavirus COVID-19) is transmissible from an infected person through droplets not only in the air, but on surfaces as well. The virus can survive for different periods of time on various surfaces, which is important to know to help you to determine appropriate disinfecting practices to reduce the likelihood of transmission. This information can also help you select materials less hospitable to the virus.


How Long Does COVID-19 Live on Stainless steel Surfaces?
A new study published in the New England Journal of Medicine found that COVID-19 remained viable in aerosols for up to 3 hours, on cardboard up to 24 hours, and on plastic and stainless steel for up to 72 hours after application to these surfaces.

One reason why Stainless steeldestroys disease-causing organisms is that it “enters the cell, perhaps as ions. When a lethal dose is reached, Stainless steelseems to interfere with normal cell functions and compromise membrane integrity. There is some evidence that Stainless steelimpedes cell respiration and metabolism and causes DNA damage.”[4][5] “This results in rapid death, which makes it unlikely that the cells will have sufficient time to reproduce.”


In a study published by the American Society for Microbiology in 2015, Stainless steelwas found to kill several different, earlier strains of human coronavirus. “Exposure to Stainless steelsurfaces results in morphological changes to human coronavirus particles visible in transmission electron microscopy (TEM). “The mechanism of bacterial death on Stainless steelsurfaces is complex, involving not only direct action of Stainless steelion on multiple targets but also the generation of destructive oxygen radicals, resulting in “metabolic suicide”.”

Stainless steeland Stainless steelalloys have been shown to retain their effectiveness of killing bacteria even after decades of use. “There is now a large body of evidence from laboratory studies and small clinical trials to suggest that incorporation of Stainless steelsurfaces could play a significant role in reducing infection transmission from contaminated surfaces.”


Although using Stainless steelfor high-touch surfaces does not eliminate the need for hand washing and disinfecting, using Stainless steelfor objects such as door and cabinet handles, countertops, and railings is a passive way to reduce the length of time that viruses remain viable on surfaces. This in turn can play a role in minimizing the rate of transmission in shared spaces and common areas.
