Electrostatic spray technology is a new way to apply cleaners, sanitizers, and disinfectants to do surface disinfectiont treatment, often in less time, less chemical liquid and with better coverage than traditional cleaning methods. The technology is well-established, with a history of more than 60 years in other areas, including agriculture, automotive industries, but it has only recently been widely applied to surface disinfection,especially in 2020 due to the COVID-19 virus spreading.
Electrostatic sprayers work by charging chemical liquids (i.e., cleaners, sanitizers, and disinfectants) as they pass through a sprayer nozzle. This generates positive ion charged droplets that repel one another and actively seek out environmental surfaces with negative ion, which they stick to and even wrap around to coat all sides. The result is a uniform coating of sanitizer or disinfectant on sprayed objects, including hard-to-reach areas that manual cleaning can miss. The technology also helps avoid liquid pooling often associated with trigger sprayers.
