On Monday, the Denver Broncos posted a weird video to its Twitter account. In the video, the NFL team’s players walked through a gate that sprayed a fine mist onto them. “Time for work,” the tweet read. “But first, we sanitize.” The video has 3.4 million views as of this publication.

The Broncos’ lead writer Aric Dilalla tweeted more details: “This disinfecting spray helps protects [sic] the players from COVID-19 by killing microbes and pathogens instantly by forming millions of nano-crystalline structures. Players walk through the non-toxic spray as they walk out to the practice field for a walkthrough or practice.” A team spokesperson confirmed to British tabloid the Daily Mail that the product being sprayed was “MicroSure, a nontoxic disinfectant used against viruses like E. Coli and coronavirus.”

On Twitter, people were dubious; an emergency doctor in the U.K. called it “complete nonsense.” To prevent the spread of the coronavirus, the Centers for Disease Control and Prevention recommends social distancing, hand-washing, wearing a mask, and cleaning and disinfecting surfaces, though it has updated its guidance to note that the virus “does not spread easily” on surfaces. Scientists have established that the coronavirus spreads primarily through person-to-person contact via tiny droplets emitted when a person coughs, sneezes, or talks, though it may also be airborne and travel distances greater than six feet.

The Broncos appear to be attempting to disinfect the surfaces of the players with a fine mist of a disinfectant called MicroSURE. Finding details about the product and its manufacturer isn’t easy.

The Illinois-based Twitter handle @microSURE_, which has four followers as of this publication, retweeted several tweets featuring the Broncos video. One retweet included the reply: “Thank you for your trust and support @Broncos”. The display name on the Twitter account is “microSURE Hand Sanitizer,” and its description says “Alcohol-Free Hand Sanitizer based on 15-year-old technology and material science.” It points visitors to the MicroSURE website.
