When hygiene matters most
The novel coronavirus, also known as SARS-CoV-2, is spreading worldwide. The main human-to-human transmission pathway appears to be droplet infection. With simple hygiene measures, each individual can help to protect themselves and others from the life-threatening lung disease and stem its rapid spread. Our topic special is dedicated to the most effective methods of protection against infection.
Kärcher steam cleaners against the coronavirus
Kärcher arranged to have the effectiveness of its steam cleaners in fighting viruses tested in an independent laboratory. The result: if used properly, the machines remove up to 99.999% of enveloped viruses*, such as the coronavirus or influenza, and 99.99% of common household bacteria** from hard surfaces. As at the present time disinfectants are to be reserved primarily for outpatient and inpatient care, steam cleaners can make a valuable contribution to general hygiene – both in private households and in commercial and industrial use.
*Tests have shown that with spot cleaning of 30 secs at max. steam level and direct contact to the cleaning surface with the Kärcher steam cleaner 99.999% of enveloped viruses such as coronavirus or influenza (excluding the Hepatitis-B virus) can be removed on common smooth household hard surfaces (test-germ: Modified-Vaccinia-Ankara-Virus).
**When thoroughly cleaning with the Kärcher steam cleaner 99.99% of all common household bacteria will be killed on common smooth household hard surfaces, provided the cleaning speed of 30 cm/s at max. steam level and direct contact to the cleaning surface (test-germ: Enterococcus hirae). 99.999% with professional steam cleaners SG(V) according to EN 16615:2015-06, PVC floor, test germs: Enterococcus hirae ATCC 10541.
The laboratory test
Enveloped viruses such as the coronavirus can be neutralised with high temperatures. As viruses are not germs or living organisms, experts also talk about virus inactivation. In the laboratory a certified test virus (Modified-Vaccinia-Ankara-Virus), which is representative for enveloped viruses, was distributed on a hard surface. This area was then cleaned with the hand nozzle of a steam cleaner and the appropriate microfibre pad. It was demonstrated that a significant reduction of up to 99.999% of the viruses could be achieved at maximum steam pressure and with a cleaning duration of 30 seconds on one area.
Kärcher tested steam cleaners for domestic use as well as machines for professional use. Whether the steam is produced in a boiler or in a water heater, it doesn't affect the result in combating the virus; both technologies achieved a comparable result in the laboratory.
Trigger of infectious diseases
Infectious diseases can be caused by various pathogens, including viruses, bacteria or fungi.
How can you protect yourself and others from infection?
Since there is currently no vaccine against the coronavirus, it is very important to follow simple hygiene measures - both in private surroundings and in personal hygiene as well as in public spaces.
Why hygiene measures are so important in times of Corona
In a clean, well-maintained environment that is cleaned regularly, the risk of transmission of pathogens is minimised considerably. Surfaces are no longer a breeding ground for germs, bacteria or viruses. Even in places that are difficult to access, the pathogens are eliminated more thoroughly.
Cleaning measures for cleanliness and hygiene at home and in public places.
