Coronavirus kills 99.999%
Kärcher has tested the effectiveness of steam cleaning machines to combat viruses in an independent laboratory. Conclusion: When used properly, the machines remove 99.99% of enveloped viruses such as coronavirus and influenza virus and 99.99% of common household bacteria ** from hard surfaces.
Since currently disinfectants are primarily used for the care of patients, steam cleaning machines can make an important contribution to maintaining general hygiene both in the home environment and in commercial and industrial use.
Enveloped viruses such as coronavirus SARS-CoV-2 can be neutralized at high temperatures. Since viruses are not microbes or living organisms, experts also talk about virus inactivation. An approved test virus (Modified-Vaccinia-Ankara-Virus), representing enveloped viruses, is distributed on a hard surface in a laboratory environment. This surface was then cleaned with a steam cleaning machine. It has been proven that viruses can be cleaned up to 99.999% at maximum steam pressure and when a spot is cleaned for 30 seconds.
