We have received several inquiries about the effect that GreenEarth Cleaning has on the
coronavirus (COVID-19) as I'm sure you have had as well. Here are several facts that address the issue to the extent that it can now be addressed:
- Because GreenEarth's pure D5 dry cleaning fluid has the highest flash point of any of the alternative solvents (170F), the GreenEarth dry cleaning process allows the clothes to be dried at the highest drying temperature, 158F, which is equivalent to 70C.
- At this point in time, the specifics of the epidemiology of the COVID-19 have not been identified. However, the World Health Organization issued its update to its table of Thermal Inactivation of Bacteria, Viruses, and Protozo in January 2015 (copy attached). As you can see, many bacteria, viruses and protozoa are inactivated at 70C or 158F.
- Additionally, the amount of inactivation is a logarithmic function of the amount of time the temperature is applied. The standard drying time at 158F in the GreenEarth Cleaning process is more than 30 minutes, enough time to inactivate most of the viruses shown.
- Given the information available at this point in time, because GreenEarth dries at the highest temperature for the longest period of time, we believe it is fair for you to make the representation that while we do not know the specific behavior of the COVID-19 virus yet, if it behaves similarly to other viruses that have been tested, the GreenEarth process is the most effect dry cleaning method available to inactivate bacteria and viruses and to potentially inactivate the COVID-19 virus as well.
