Fogging & Disinfection Services: When Does Your Toronto Business Need Them?

Conventional surface wiping disinfects what you can see and reach. But pathogens don't respect the limits of a cleaning cloth — they settle on the undersides of chairs, behind equipment, inside air vents, and in areas that routine cleaning skips entirely. Electrostatic fogging changes the geometry of disinfection by charging microscopic droplets that wrap around and cling to surfaces from every angle, including those that can't be wiped.

How Electrostatic Fogging Works

An electrostatic sprayer atomises a disinfectant solution into very fine droplets and applies a positive electrical charge as they leave the nozzle. Since most surfaces carry a neutral or slightly negative charge, the positively charged droplets are attracted to them — wrapping around objects rather than simply falling on top. This results in 360-degree surface coverage, including vertical surfaces and undersides, with far less product used than conventional spraying or wiping. The disinfectant typically used meets Health Canada's approved list for human coronavirus, norovirus, and other pathogens.

Fogging vs. Regular Disinfection: When Is Fogging the Right Choice?

• After a confirmed or suspected infectious illness outbreak (COVID-19, norovirus, flu)
• Seasonal deep disinfection before school terms, flu season, or post-summer reopening
• High-density spaces where thorough manual disinfection is impractical — gyms, transit facilities, warehouses
• Healthcare and dental facilities requiring clinical-grade disinfection between procedures
• Food processing facilities requiring full equipment and facility disinfection between production runs
• Daycares and schools after a communicable illness incident
• Event venues between large-scale events
• Any facility where manual cleaning has limitations due to complex geometry or density of equipment

Industries That Benefit Most from Regular Fogging

• Medical and dental clinics — monthly fogging between thorough manual cleans
• Gyms and fitness centres — post-close fogging of locker rooms and equipment zones
• Schools and daycares — term-end full-facility fogging
• Restaurants and food production — fogging of non-food-contact areas and cold storage
• Auto dealerships — showroom and service area fogging
• Offices — seasonal fogging as a complement to regular cleaning programmes

What to Expect During a CMG Clean Fogging Service

CMG Clean fogging technicians arrive in full PPE and begin by removing or covering any items that shouldn't be exposed to disinfectant — open food, some electronics, fish tanks. The fogging process itself takes 15–45 minutes depending on facility size. The disinfectant requires a dwell time of 10–15 minutes before the space can be re-entered. Most facilities are ready to reoccupy within 30–60 minutes of the technicians leaving. We provide a service certificate following each fogging visit documenting the products used, concentration, and area treated.

Is Fogging Safe for Employees and the Public?

All disinfectants used by CMG Clean for fogging are approved by Health Canada and specifically evaluated for use in occupied buildings — though the space must be vacated during application. Products are selected based on the environment: a food production facility requires different disinfectants than a dental office. We choose quaternary ammonium or accelerated hydrogen peroxide-based solutions that break down rapidly into harmless compounds after the required dwell time, leaving no harmful residue.
