A visibly clean surface isn't necessarily a disinfected one. For offices, medical facilities, schools and gyms, proper disinfection is essential to reducing the spread of illness. Here's what best-practice disinfection actually involves.
Cleaning vs. sanitizing vs. disinfecting
- Cleaning removes dirt and most germs using soap and water.
- Sanitizing lowers germs to a safe level as judged by public health standards.
- Disinfecting kills germs on surfaces using EPA-registered chemicals.
The best programs clean first, then disinfect — because disinfectants work best on already-clean surfaces.
Respect dwell time
Every disinfectant has a required contact (dwell) time — the number of minutes it must stay wet on a surface to be effective. Wiping it off too soon is one of the most common mistakes. Trained crews follow label instructions exactly.
Target high-touch surfaces
Prioritize the places hands go most: door handles, switches, railings, shared electronics, restroom fixtures and breakroom surfaces. These deserve more frequent attention than open floor space.
Prevent cross-contamination
Color-coded cloths and tools (e.g., one color for restrooms, another for kitchens) prevent spreading germs from one area to another. It's a simple system that makes a big difference.
Consider electrostatic spraying
For large or complex spaces, electrostatic sprayers apply disinfectant evenly, wrapping around surfaces for thorough coverage in less time — useful for routine service and outbreak response alike.
Document your protocols
Consistent, documented procedures — including which products are used and where — provide accountability and peace of mind, especially in healthcare and education settings.
