With the hightened awarement of infection control with the Coronavirus Covid-19 pandemic and the enquiries we are receiving regarding decontamination/sanitisation of areas using fogging treatments, we thought it would be helpful to dedicate a topic to explain more in depth about fogging procedures and how we do it. This will hopefully allow you to understand more what is involved, the different ways its done and if it will be right for your needs.
There are generally two ways fogging is carried out – either Thermal Fogging with a thermal fogger machine, or Cold Fogging with a ULV (Ultra Low Volume) cold fogger machine. We use both systems and will choose the most appropiate one depending on the treatment being applied and the type of premises. Sometimes, we will use a combination of both systems.
The antimicrobial cleaning solution we use is one of the first in the UK to be certified and tested to destroy CORONAVIRUS SARS-COV 2 WHICH LEADS TO THE ILLNESS COVID-19.

ULV Cold Fogging
The ULV cold fogging machine uses a water based solution – ours is antimicrobial (anti bacterial and anti viral) and is safe and non toxic to humans or pets. As the name suggests, the solution is not heated, but misted under pressure so the solution is atomised – the machine will produce droplets of a micron size normally between 20 to 60 microns. These droplets are small enough to be seen as a ‘fog, but not as a dry smoke like thermal fogging. The fog created by a cold fogger will still sanitise the air as it will hang in the air for a period of time, but it will then drop onto surfaces leaving a moist layer. The layer left can be compared to light condensation. This moisture dries quickly without drips, even on plastic and glass surfaces, but stays in contact with the surface long enough to be effective against the contamination. The solution works by breaking down the virus on contact and can leave a barrier to futher infections for a period of time. As the solution is atomised it can be dispersed over long distances – up to ceilings and over desks, furniture – getting to areas not possible by other means. Large areas inside can be covered quickly and effectively. The areas need to be empty of people when its being applied – mainly to safeguard in case of allergies, not because our solution is toxic to us. Normally a period of 2 hours is sufficient for people to then return. ULV cold fogging is extremely effective for decontamination as the antimicrobial cleaning solution stays in touch with the surfaces for a period of time to be effective against bacteria and virus’s. It also leaves a ‘barrier’, for a period of time after.
A thermal fogging machine will heat the solution being used causing it to vaporise into droplets of 10 to 15 microns. This creates a dry ‘fog’ which is normally very visible because it looks like smoke and has the advantage of being safe to use around more wet sensitive areas – such as domestic properties or areas with lots of electrical appliances. The solution used is again antibacterial and antiviral and it is water based, not solvent based.
At New Look Clean we will first do a ‘touch surface’ clean – using certified antimicrobial cleaning solution to clean the areas such as light switches, plug sockets, surfaces, computers etc using cloths which are continually replaced to prevent cross infection.
We will then use our fogging treatment – either ULV cold fogging or thermal fogging, or a combination of both.
Thermal fogging is preferred in domestic environments due to the nature of it being a completely ‘dry’ system. In commercial environments we will generally use cold fogging when possible but may use a combination depending on the building type and contents.
We hope this gives you more information on how the fogging is carried out. If you need anymore information, please do not hesitate to get in touch.
