A Definitive Guide to Fogging and its Cleaning Importance

The COVID-19 virus reproduces quickly, with droplets from coughing, sneezing, and saliva droplets from human mouths spreading to anything they encounter. When a person with COVID-19 coughs, sneezes or speaks, droplets containing the virus can be spread a short distance and quickly settle on nearby surfaces.

Fomite transmission, as it is known, occurs on a variety of surfaces, including door handles, electronic devices, touch screens, and handrails. If you touch those surfaces or objects and then touch your mouth, nose, or eyes, you could become infected with the virus.

Washing walls, mopping floors, spraying desks, workstations, door handles, and other surfaces with antibacterial spray are the simplest ways to keep areas safe.

However, this is insufficient in some cases, and a thorough deep clean is needed, especially in quarantined areas. Among the different methods to rid homes, offices, and play areas of the COVID-19 virus droplets, bio fogging proves to be one of the most effective.

What is Fogging?

Bio-fogging is a sterilization technique that produces an electrostatically charged wet mist that kills a high percentage, if not all, of pathogens that traditional cleaning can’t reach. It’s a tried-and-true method of sterilizing a large surface area, including walls, ceilings, furniture, carpets, and floors.

During treatment and two hours afterwards, the treated room must be empty of people before it can be later reoccupied without further decontamination or ventilation. Decontamination can last up to 30 days and can be done once a month to ensure long-term protection.

How Does Fogging Work?

Fogging uses an antiviral disinfectant solution that cleans and sanitizes broad areas of a building rapidly and efficiently (to BS EN 14476 standards). In the air and on surfaces, it will destroy the virus and other biological agents. The job entails spraying a fine mist with a spray gun and then allowing it to evaporate for 6 hours.

The contractor must wear a chemical suit, gloves, an air-fed ventilator, and a sealed mask, among other things, to complete the task. When using the fog, mist, or vapour process, the contractor must ensure that the active chemical is used in the right concentration. This means there’s enough for it to work effectively, but not enough to leave a residue that may be hazardous for a long time after treatment is finished.

Advantages Of Fogging

Due to the ways people come into contact with the Coronavirus, which is a form of germ contamination, anti-covid bio fogging is essential in the following ways:

Sterilizes Tough-to-Reach Areas

There was no way to simplify the care of particular areas using traditional techniques. Anti-Covid fogging technology, on the other hand, seamlessly distributes treatment chemicals to hard-to-reach areas. Water drains, air ducts, ledges, wall joints, rims, and narrow corners are some of the most challenging places for traditional methods of sterilization to get to.

Disinfection Of Electronics

When it comes to sterilizing electrical components and computer hardware, fogging is highly successful. Typical electronic components are vulnerable to moisture causing electrical damage and preventing sterilization. Fortunately, modern bio fogging treatment is misty and does not contain moisture, affecting business machine hardware performance.

Saves Time

Fogging services save time and energy because, unlike conventional treatment methods, it disinfects in hours and covers the entire region. Furthermore, during the short fogging period, mist spreads across the whole facility, protecting visitors, managers, contractors, and workers for at least 30 days.

Factors to Consider When Fogging

If a workplace uses a potentially hazardous product, employees must be informed and trained to be aware of the risks and how to work safely with them. The following information should be included in the training:

  • How to read product labels and Safety Data Sheets
  • Usage, storage, and disposal of a hazardous substance in a safe manner
  • The procedure to take If a dangerous substance is found in the air and a worker is exposed.
  • All protocols to be followed in the event of a possibly hazardous substance emergency.

Direct Spray Contact With People

Spraying disinfectants on people, regardless of the circumstances, is dangerous. In this situation, the fog should not be dispersed in the cabinet, chamber, or tunnel where people are working. According to the World Health Organisation, dispersing disinfectants on humans may be dangerous and does not affect virus transmission. Viruses are spread by touch and droplets.


Even with the invention of the vaccine, it is still vital to practice strict hygiene steps, such as disinfecting and cleaning often touched items and surfaces, highlighting the importance of bio fogging in the area you spend the most time in.

Even when national restrictions are removed worldwide, we are likely to see waves of coronavirus infections for some time. It will worsen in the winter because more people would be inside for more extended periods with less ventilation.
