Why does most "disinfecting" not actually work?
Most surface spraying fails for two reasons: the surface is disinfected before it is cleaned, and the product is wiped away before it has time to work. A disinfectant applied over dust and soil is blocked from the pathogens underneath, and every EPA-registered product needs a specific dwell time \u2014 often several minutes of visible wet contact \u2014 to kill what it claims to kill.
We do it the way the CDC recommends. First we clean the soil off the surface, then we apply the right EPA-registered hospital-grade disinfectant and let it sit for the full label dwell time. For large or complex areas we use electrostatic sprayers that coat surfaces evenly, reaching edges and undersides a wiped cloth misses.
Then we focus where it matters. High-touch points \u2014 door handles, switches, elevator buttons, shared equipment, restroom fixtures \u2014 are where pathogens actually move from person to person, so they get priority on every visit. The result is real infection control, not the theater of a quick spray-and-wipe.
What Our Disinfection Programs Include
EPA-Registered Disinfectants
Hospital-grade disinfectants matched to the pathogens of concern and applied per label directions for proven efficacy.
Correct Dwell Times
Surfaces stay visibly wet for each product’s required contact time — the step most quick cleanings skip, and the one that actually kills pathogens.
Two-Step Clean & Disinfect
We clean soil first, then disinfect, because disinfectant applied over dirt cannot work. This is the core CDC-recommended sequence.
Electrostatic Application
For large or high-touch areas, electrostatic sprayers wrap surfaces in an even, charged coating that reaches edges and undersides.
High-Touch Point Focus
Door handles, light switches, elevator buttons, shared equipment, and restroom fixtures get priority attention every visit.
Documented Protocols
Checklists and product logs document what was disinfected, when, and with which product — useful for audits and peace of mind.
