GreenEarth Cleaning Awarded U.S. Patent for Anti-Viral Drycleaning Process: Cleaning method designed to provide protection from lipid-layer viruses

KANSAS CITY, Mo. — GreenEarth Cleaning, a company specializing in environmentally friendly drycleaning processes, was recently awarded a U.S. Patent for the development of an anti-viral cleaning methodology which has been incorporated into the GreenEarth Cleaning System.

The patent enables GreenEarth affiliates to integrate vaporization into the drycleaning cycle to deliver the highest level of protection from current and future lipid-layer viruses.

“In the spring of 2020, after the World Health Organization (WHO) had declared the COVID-19 outbreak a global pandemic, we contracted with MRI Global, an independent laboratory approved for testing with Sars-CoV-2,” says Tim Maxwell, president of GreenEarth Cleaning.

“Our intent was to determine the effectiveness of our system in penetrating the lipid layer of the coronavirus using a high drying temperature of 158 degrees Fahrenheit (70 degrees Celsius) for 30 minutes. We were surprised when the initial reports showed only a 14.28 percent deactivation efficacy with heat alone. So, we went back to the drawing board.”

Initially, through manipulation of the washing, extraction, and drying steps, GreenEarth was able to achieve deactivation levels of 75 percent. In response to that result, GreenEarth created a silicone vapor program component that achieved a deactivation level greater than 98 percent on SARS-CoV-2 contaminated wool fabrics.

“Once we solidified the vaporization and process and attained this result on a consistent basis, we added the anti-viral cleaning methodology to our suite of offerings available to GreenEarth affiliates,” says Maxwell. “We continue to achieve extremely high viral eradication without adding aggressive chemistry. With this innovation, we are providing an expanded level of care without doing harm to the environment, people, or their garments.”

Early in 2023, GreenEarth technical support began incorporating the necessary program modifications into all GreenEarth affiliate machines.

“With this advancement, we feel that our affiliates are better prepared for the potential arrival of any possible new variant of COVID or the next virus,” adds Maxwell.
