an efficient, effective, and economical way to deep-clean contaminated surfaces
Cross Town Cleaning saw the use of Electrostatic Sprayers (ESS) for disinfecting surface increase dramatically during the Covid pandemic. The threat of Covid, thankfully, has declined, but the benefits of ESS continue.
The website Infection Control Today has an informative article about how ESS works and the advantages it provides. Following is an excerpt.
What is ESS and How Does It Work
An ESS is based on the universal interaction between positive and negative forces. (Remember rubbing a balloon to create static and then sticking the balloon to a wall or your head? Same general principle.) Most surfaces have a (grounded) negative surface charge. The sprayer positively charges the disinfectant as it passes through the sprayer nozzle, and the charged disinfectant droplets seek out and stick to negatively charged surfaces—that is, they produce static.
Like magnets that shoot away from each other when held rear to rear, the positively charged particles in the droplets repel each other and spread out—at many times the force of gravity—looking for exposed surface. The spray droplets can also reverse direction, moving against gravity and coating all sides of the target object. Thus, one of the advantages of electrostatic spraying is that it offers “wraparound” coverage, meaning it can quickly coat high-touch surfaces that may be time consuming to clean such as pens, light switches, faucets, and keyboards.
Because the solution comes out in a thin mist, it covers the targeted area evenly. Sprayers with smaller droplet sizes may be safer for sensitive equipment. Surfaces that are already covered will repel the charged droplets, which redistributes them, making the task that much more efficient and reducing the chance of over application.
Efficient and Economical
In addition to time savings, the ESS offers cost savings. Used properly, the ESS can save on disinfectant and cut cleaning time by 50% or more, compared with spray-and-wipe methods. Moreover, according to an EPA decontamination study, because an ESS provides more uniform distribution, using a minimal amount of solution, it significantly reduces waste streams and costs associated with liquid hazardous waste disposal. Compared with a backpack sprayer, the ESS generated almost 75 times less liquid waste.9
Cross Town Cleaning has been using ESS since before the pandemic and is skilled in its application. Visit crosstowncleaning.com to find out about using ESS in your building or for more information about all of our cleaning and sanitizing services.
