How to deactivate virus

  What challenges are there, for cleaning surfaces?


The removal of enveloped viruses from contaminated surfaces up to disinfection grade “partially antiviral” involves the use of a blend from oxidative and toxic compounds, containing e.g. alcohols and peroxides.


That will reduce the amount of Corona virus to ~ 0.1‰ .


These partially antiviral mixtures are not an option for on-the-spot frequent use in households, for hand or surface hygiene.


Still, the envelope suggests the use of less aggressive cleaning agents and procedures, with highly promising effect in view of virus de-activation and removal, if conducted properly and still suitable for everyday use.


Alcohol removes greasy ingredients from surfaces. In high concentrations, it is a valid disinfection agent. Its frequent use though is harmful for the skin, and for leather.

Moreover, it is not available in infinite amount, and expensive.


Alternative cleansing liquids, preferentially adsorbed in wipes, may include some amount of alcohol, but they achieve their goal mostly by a mix of proper surfactants, like tensides, with ethoxylated alcohols, and water and combined with proper application procedures. These include the use of gloves, thorough wiping with foam followed by incubation such that smallest volumes are assessed by the agent, subsequent flushing with water and drying. Sensitive surface (skin, leather) will benefit from the tailored product of a 2-component system, addressing cleaning with subsequent surface cosmetics.
Such a solution is in accordance with the recommendations of relevant institutions.
