Disinfectant Fogging

COVID-19, this novel-coronavirus as others call it, has forced everyone to go back to the drawing board, to ask the basic and fundamental question, how do we disinfect?

Questions Abound

In a non-pandemic time, the answer is easy to find, use a List N EPA approved disinfectant, spray and wipe surfaces. In pre-COVID days this answer is typically sufficient, the line of questioning ends here. But COVID has changed that. COVID has forced us to ask other?, more complex questions. 

  • A manpower question: If we’re disinfecting surfaces on a more regular basis, how do we keep this up? 
  • A question of size: What about large spaces like churches, schools and government buildings — how is a large facility disinfected regularly without the Governor declaring a State of Emergency and enlisting the National Guard? 
  • A question on material: What about porous materials that are not so easily sprayed and wiped? 

A Breakthrough

The professional cleaning industry has responded with a break-through technology: disinfectant fogging and the use of Electrostatic Spraying Systems. These technologies are revolutionary, innovative and give incredibly satisfying answers to these questions. 

Electrostatic spraying is able to accomplish something a non-traditional sprayer cannot, positively charged droplets and small droplets. By positively charging the disinfectant cleaner the droplets are then attracted — dare I say pulled — to the negatively charged surfaces. The size of the droplets allows this process to happen. And so an electrostatic sprayer is able to produce droplets that are 900 times smaller and two times more effective at covering surfaces. 

The Implications Are Obvious

Electrostatic spraying changes how we respond to COVID (and other infectious threats to public health). The truth is, the better a chemical is able to be fully dispersed the more efficient its disinfecting ability is. If a professional cleaning team is able to use spraying and fogging, it answers the manpower question, a small skilled crew accomplishes this. It also answers the question of size, somewhat related to manpower, spraying and fogging is effective especially in large spaces. And it also answers the porous material question, this soft material isn’t wiped, it’s sprayed. 

The EPA has realized the value of fogging and electrostatic spraying and is actively working to update its guidance.
