Electrostatic Disinfection vs. Hand Cleaning

When it comes to cleaning surfaces and objects, traditional dry and wet dusting tends to be the first methods that come to mind. While these cleaning techniques are tried and true, they do little more than spread filth around, unless the rags used are washed regularly. Dry dusting kicks up resting particles, redistributing them into the air and onto other surfaces. Wet dusting can involve harmful cleaning chemicals and make it hard to reach certain spots or objects. For schools, daycares, restaurants, gyms, homes, retirement communities, businesses, etc. , there’s a more effective method for disinfection and it involves the use of electrostatic spraying.

What Is Electrostatic Disinfection?

Electrostatic sprayers (also known as electrostatic foggers) used in cleaning and disinfecting applications get their start from the manufacturing industry, and specifically from the painting industry. Electrostatic spray surface cleaning is the process of spraying an electrostatically charged mist onto surfaces and objects. Electrostatic spray uses a specialized solution that is combined with air and atomized by an electrode inside the sprayer. Subsequently, the spray contains positively charged particles that are able to aggressively adhere to surfaces and objects. Because the particles in the spray are positively charged, they cling to and coat any surface they’re aimed at.

For awkwardly shaped objects or hard to reach places, electrostatic disinfection allows the chemicals to coat surfaces evenly, and envelope objects—even if the mist is only sprayed from one side. After the spray is applied, the sanitizing agent works to disinfect the covered surfaces. Disinfect Charleston uses electrostatic spraying as their primary disinfection method in clients businesses and homes.

How Does Electrostatic Disinfection Work?

Electrostatic spray is electrically charged, allowing the appropriate sanitizers, mold preventatives and disinfectants to wrap around and evenly coat all types of surfaces for a more complete clean. As the chemical exits the electrostatic sprayer, it’s given a positive electrical charge. The droplets then become attracted to all negative surfaces, covering the visible area, underside and backside, with the sanitizing agent. Surfaces that are already covered will repel the spray, making the method extremely efficient.

Is Electrostatic Spray Disinfection Right For My Home or Business?

If you are looking for a more complete disinfection solution to potential contamination (e.g. coronavirus / COVID-19) in your home or business, electrostatic disinfection is the way to turn. It can provide reassurance to your customers, peace of mind for your family, or used as a marketing/selling point for your business.

The main features and benefits of electrostatic spray disinfection include:

  • Touchless application. There is no need to touch or wipe the surfaces (dependent on solution spraying). 
  • Reduces the time it takes to cover and disinfect all surfaces and hard-to-reach places by 50% compared to conventional methods
  • Reduces chances for cross contamination. In most cases, a spray-and-wipe technique can move bacteria from one surface to another. Cross contamination can be considerably reduced due to the touchless effect. Improves infection control and the spread of viruses such as coronavirus, influenza, MRSA, HIV and many others
  • Applies chemicals in a more efficient, controlled manner, eliminating the dangers of overuse
  • Liquid adhesion and coverage. Using the electrostatic sprayers will enable a quick and effective chemical application. As fully-charged droplets hit the surface they create an even spread. Particles hold their cationic charge for approx. 2-3 seconds – preventing drips. This allows the solution to cover hidden and shadowed areas. Electrostatic sprayers have been designed to meet dwell times for solutions so they can work to their full capabilities.
