Electrostatic Disinfection: What It Is and How to Specify It
Electrostatic disinfection applies disinfectant through a sprayer that gives the droplets an electrical charge. The charged droplets are drawn towards surfaces and wrap around them, including the undersides and edges of handles, chair frames and fixtures that a cloth or ordinary spray can miss.
Used properly, it is a useful addition to routine cleaning. Used as a substitute for cleaning, it gives a false sense of security. This guide explains where it fits and what to put in a specification.
How it works
The sprayer charges the disinfectant as it leaves the nozzle. Because the droplets carry the same charge, they spread out evenly instead of clumping, and they are attracted to surfaces. The result is more even coverage of irregular shapes in a single pass.
The disinfectant still has to do the work. It must be suitable for the surface, applied at the right dilution and left wet for the contact time stated on its label.
Where it adds value
Busy offices and open-plan floors, where many people share desks, handles and equipment
Public-facing and government buildings, where visitor numbers are high
Warehouses and industrial sites, where shift workers share tools, vehicles and break areas
Clinics and medical offices, as part of an infection-control routine
Food service and hospitality areas, subject to inspection
After a reported illness, as a one-off treatment of affected areas
What to specify
The disinfectant. Name the product and ask for its product data sheet and Safety Data Sheet. It should be approved for use in your setting and effective against the organisms that concern you.
Trained operators. Applicators should be trained in the equipment, dilution, contact times and protective equipment.
Clean first, then disinfect. Disinfectants work poorly on dirty surfaces. The scope should state that visible soil is removed before spraying.
Areas, frequency and timing. List the rooms and approximate floor area, how often each is treated, and whether treatment is scheduled or on request. Most sites schedule it after hours.
Records. Ask for a record of each visit showing the areas treated, the product used and who carried out the work.
Our guide to workplace cleaning and disinfection covers how to choose products and where spraying fits.
How NHJ provides it
We offer electrostatic disinfection as a scheduled service or a one-off treatment, alongside routine cleaning. Each programme starts with the areas to be treated, the product to be used and the timing, agreed in advance and recorded at each visit.
Frequently asked questions
Does electrostatic disinfection replace cleaning? No. Surfaces must be cleaned first. Electrostatic spraying improves how evenly disinfectant is applied afterwards.
Is it safe for offices? When the product is suitable and applied as directed, yes. It is normally done after hours, and surfaces can be used once they are dry and the label's contact time has passed.
How often is it needed? It depends on traffic and risk. High-use areas such as washrooms, break rooms and reception may need it more often than general office space.
