Triethylene glycerol is a colorless, odorless liquid used in myriad ways including as a finishing agent for different textiles and as an ingredient in lubricants and wallpaper stripper. But that makes it sound like a dangerous chemical compound. It’s also commonly used to produce the artificial fog prevalent at concerts and Las Vegas production shows.

And by the way, it kills virus particles. The COVID kind.

The Grignard Company based in Rahway, New Jersey, has produced a first-of-its-kind continuous antimicrobial air treatment called Grignard Pure that kills more than 98% of coronavirus particles in the air, and on January 15, the U.S. Environmental Protection Agency (EPA) approved an emergency exemption request for the use of Grignard Pure “as an additional tool in limited situations to aid in the fight against COVID-19” for Georgia and Tennessee state governments.
