As wineries are considered essential businesses during the Covid-19 epidemic, it is essential to protect employees and prevent the further spread of the virus. Disinfecting common surfaces is an absolute must! Ethanol is a highly effective "people friendly" surface disinfectant when used at the correct strength. VA Filtration USA has 90% by strength grape based ethanol available for immediate shipping or collection.
How to use ethanol for disinfection?
We would recommend the following protocol for disinfection:
Dilute 90% ethanol down to 70% strength by adding water (7 parts 90% ethanol to 2 parts water). The dilution lengthens the evaporation time of the mixture, allowing sufficient time for the ethanol to disinfect the surface (60 seconds minimum contact time).
Add the mixture to a spray bottle and spray on surfaces ensuring complete coverage and wait for a minimum of 60 seconds. Wipe surfaces with a clean dry cloth if needed.
How effective is ethanol against Covid-19?
“Ethanol at concentrations between 62% and 71% reduced coronavirus infectivity within 1 min exposure time by 3.0–4.0 log10,” according to investigators with University Medicine Greifswald and Ruhr University Bochum in Germany whose study ran as an article in press in the Journal of Hospital Infection (JHI)
What the above means, is that 99.9% - 99.99% of the effectiveness of the virus is reduced in 60 seconds when in contact with 70% ethanol.
Can it be used on hands?
Yes. It is safe to use on exposed skin but can lead to drying of the skin. Use a personal hand cream to keep skin from drying out after using the spray.
