How Electrostatic Spray Technology Reduces School Absenteeism
A single sick child in a classroom can infect up to 80% of their classmates within a week if surfaces aren't properly treated. Traditional cleaning methods—mop, wipe, move on—miss the backs of desks, chair undersides, and hundreds of micro-surfaces that students touch daily. Electrostatic spray disinfection was developed to close that gap.
How Electrostatic Spray Works
Electrostatic sprayers positively charge the disinfectant particles as they leave the nozzle. Because most surfaces carry a neutral or negative charge, the particles are electrostatically drawn toward and wrap around the surface—including edges, undersides, and hard-to-reach areas. This 'wraparound effect' achieves up to 360° surface coverage without additional manual wiping.
The Coverage Advantage Over Traditional Methods
Traditional spray-and-wipe methods typically achieve around 60–70% surface coverage. Electrostatic application consistently achieves 95%+, according to studies published in the American Journal of Infection Control. In a classroom with 30 students, that 25–35% coverage gap represents dozens of contaminated surfaces that a standard clean completely misses.
The Absenteeism Data
A pilot programme run across elementary schools tracked illness-related absences before and after implementing electrostatic disinfection. Over two academic years, schools with electrostatic treatment reported a 30% reduction in illness-related student absences compared to control schools. Staff sick days fell by a similar margin—a direct reduction in supply teacher costs and administrative burden.
What This Means for School Budgets
Every percentage point of attendance improvement carries real value. Schools often receive funding tied to average daily attendance, meaning better attendance directly improves budget outcomes. Reduced teacher sick-day supply costs and lower administrative overhead from tracking absences are measurable savings that can be presented alongside the cleaning contract cost when building the case for upgraded protocols.
Dolpo's School Cleaning Protocol
Dolpo's school cleaning programme integrates electrostatic disinfection as a scheduled element, not a one-off service. During term, full electrostatic treatment cycles run on every classroom weekly, with daily manual cleaning between treatments. High-traffic areas—corridors, cafeterias, and toilet blocks—receive daily treatment.

The Bottom Line
Electrostatic spray isn't a marketing buzzword. It's a documented improvement in surface coverage that measurably affects how illness spreads through a school. Schools that haven't adopted it are accepting a preventable and quantifiable risk.
