Why is electrostatic disinfecting better than wiping?

Jul 28, 2020

Electrostatic spray coating isn’t new technology. It’s been around since the 1940s, where it was understood to be the best way to rapidly apply an even coat of liquid to almost all surfaces. Recently, commercial cleaning companies have started using electrostatic sprayers to distribute disinfectants. With the flu season affecting over 30 million Americans each year, and now the additional risks of the COVID-19 coronavirus, more companies rely on electrostatic technology to keep their workplaces clean and sanitized, and their workforce protected.

What is an electrostatic sprayer, and how does it work?

Electrostatic sprayers look like your typical liquid spray dispensers. They are available in a variety of styles from backpack or handheld battery-operated sprayers to large roller carts capable of coating tens of thousands of square feet per hour.

Regardless of design, all electrostatic sprayers work the same: they charge the liquid particles they dispense as they go through the nozzle. Those charged particles repel one another and cling to surfaces, forming an even coating that is effective and efficiently applied.

Think of the particles as tiny magnets. Most surfaces in the workspace have a negative charge since they are naturally grounded. Electrostatic sprayers positively charge the vapor particles, so they are attracted to the negatively charged surfaces. They also repel each other; the same way two south magnetic poles of a magnet repel each other. That ensures that it clings to surfaces with even distribution.

What are the benefits of electrostatic cleaning vs. hand cleaning?

As well as being a vastly more efficient method of cleaning large spaces like open-plan offices and schools, electrostatic disinfecting have many other benefits over cleaning by hand.

    Reduced chemical waste

Hand cleaning relies on the application of disinfectant, which is manually spread across surfaces. This method often leads to areas being missed or over-sprayed, or both. Electrostatic sprayers ensure every surface is evenly coated with the cleaning product. This means you only use as much as is necessary.

    Environmentally friendly

Less cleaning product used leads to less environmental impact. The reduced waste experienced with electrostatic sprayers results in less byproduct or run-off, making its way into the local ecosystem. If your business prides itself on being green or strives to do more to support the environment, using electrostatic sprayers for cleaning is a fantastic choice.


There are multiple ways an electrostatic disinfecting service can save you money compared to a regular cleaning service. Not only does it use less cleaning product, it’s significantly faster than traditional cleaning saving labor hours. One company states a 40 percent reduction in cleaning times

Is electrostatic disinfection effective?

Using electrostatic sprayers to dispense cleaning disinfectants is significantly more effective than cleaning by hand. Simply by ensuring an even coating and complete coverage of all surfaces, with less over-spray, gives it significant advantages. Numerous tests have shown that electrostatic spraying can be up to ten times as effective as hand cleaning.

Effectiveness doesn’t end with just distribution, though. Using electrostatic dispensers means even hard to reach areas, and commonly missed areas are uniformly cleaned and disinfected. Think of your typical office desk and all the locations where dirt and germs accumulate, and how hard they can be to get clean. The underside of the desk, nooks, crannies, around leg joints, and cable grommets, electrostatically charged disinfectants completely cover areas that regular cleaners can’t get to.

Electrostatic sprayers are used to effectively clean a variety of buildings and businesses, including:

  • Schools
  • Gyms
  • Assisted living facilities
  • Offices
  • Hotels
  • Restaurants, kitchens, and food processing plants

    …and more.

Medical offices and even surgical facilities are turning to electrostatic sprayers using hospital-grade disinfectants to ensure they are clean and as sanitized as possible.


  • Medical – Doctor’s offices, examination areas, waiting rooms, surgical theaters
  • Education – Buses, classrooms, locker rooms, cafeterias, gyms
  • Corporate – Office reception areas, bathrooms, cubicles, boardrooms
  • Catering – Vehicles, industrial kitchens, restaurants
  • Hospitality – Reception areas, hotel rooms, dining rooms, pool facilities, gyms

How long does electrostatic cleaning last?

As with all cleaning and disinfection methods, they only last as long as they are used. The majority of electrostatic cleaning products don’t create a protective barrier, meaning there is no enduring disinfectant or antimicrobial benefit. Electrostatic cleaning products are intended to disinfect surfaces on contact, killing any bacteria, germs, or viruses on those surfaces when applied. It typically doesn’t prevent reinfection.

Keep this in mind when deciding how often to use an electrostatic disinfecting service. Some workplaces, like medical facilities, gyms, and schools, are exposed to potential pathogens daily, and therefore benefit from daily electrostatic disinfection. Others, like closed offices, may only need disinfection once a week (not including shared bathrooms).

Are electrostatic sprayers effective against COVID-19?

electrostatic sprayers effective against COVID-19

Electrostatic disinfecting is suitable for treating anything their disinfecting product can kill, which includes COVID-19. When disinfecting your workplace against any pathogen, pay attention to the amount of time the solution needs to remain on surfaces before it’s guaranteed to work. Many people mistakenly wipe away disinfectants too soon, as most need to stay in contact with surfaces for several minutes. Check the labels on your cleaning solution before use to determine how to achieve the best results.

Electrostatic disinfection for COVID-19 is likely more effective than other methods specifically because it ensures an even coating across all surfaces, including the hard to reach areas. Since it doesn’t require wiping away or rubbing in of the disinfectant, it’s more likely to remain on the surface for long enough to be optimally effective. Electrostatic cleaning also dramatically reduces any direct contact your cleaning staff has with potentially infected surfaces.

Is electrostatic cleaning right for your business?

Workplaces in every industry can benefit from electrostatic disinfection, either as a periodic deep clean or as regular, routine treatments for high-trafficked areas and shared equipment. While it might seem pricey at first, It’s often faster and more cost-effective than traditional cleaning methods.

With the recent COVID-19 pandemic, the public is expressing more concern and awareness about how businesses are protecting their customers and employees with proper cleaning and hygiene practices.  Electrostatic disinfection is at the forefront of modern cleaning technologies and guarantees the best results of almost any cleaning routine.
