Disinfection Services

Here is some important information on how to properly disinfect SARS-CoV-2 (COVID-19). We also explain the difference between cleaning and disinfecting, which are part of a broad approach to preventing infectious diseases.

Our protocol is based on the information provided by the Ministry of Heath New Zealand, Centers for Disease Control (CDC), the Environmental Protection Agency (EPA) and studies done on chemical substances that have been proven effective in inactivating COVID-19. We provide clients with our health and safety, cleaning and disinfecting protocols for full transparency.

ULV Fogging and disinfecting has been used by our clients in health care, schools, business offices, food industry and various types of facilities. Disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can "efficiently" inactivate coronaviruses within a minute, according to this research. - From the database of National Center for Biotechnology Information.

Disinfection Procedures for SARS-CoV-2 (COVID-19)


Most common modes of transmission is through respiratory 
and contaminated surface contact however we're learning more about the virus every day.

COVID-19 spreads from person to person in close proximity, similar to other respiratory illnesses, such as the flu. Droplets of bodily fluids - such as saliva or mucus - from an infected person are dispersed in the air or on surfaces by coughing or sneezing. These droplets can come into direct contact with other people or can infect those who pick them up by touching infected surfaces and then their mouth, nose or eyes. 

According to scientists, droplets from coughs and sneezes can travel several meters and stay suspended in the air for up to 10 minutes.

Hand washing/drying and proper cough etiquette are very important tools in preventing the spread of illness, including colds, flu and COVID-19. If soap and water are not available and if your hands are not visibly dirty you can use  hand sanitisers (containing at least 60 percent alcohol) 

We will prepare and implement a cleaning and disinfection plan for your facility based on the cleaning requirements and risk level. We can help by setting preventive measures to stop the spread of virus in workplaces.  

This service also includes for high-risk cleaning for healthcare facilities or following a suspected, probable or confirmed case of COVID-19 

Strict health and safety procedure to be followed at all risk levels.


Cleaning is an essential part of disinfection. Organic matter can inactivate many disinfectants. Cleaning reduces the soil load, allowing the disinfectant to work. Removal of germs such as the virus that causes COVID-19 requires thorough cleaning followed by disinfection.

Disinfecting a surface will “kill” the microscopic organisms as claimed on the label of a particular product. Proper dwell time is required to inactivate virusesDisinfecting using ULV fogging ensures best surface coverage.

A maintenance procedure for your site created to reduce the spread of a wide range of pathogens. This includes frequent cleaning of high-touch areas and common areas.

Other preventive measures are:
  • Deep cleaning sites 
  • Increase the cleaning frequency 
  • Increase the frequency/scope of disinfecting. 
  • Prepare and implement COVID-19 management plan to comply with public health requirements and workplace infectious disease prevention.

  • Clean surfaces and high-touch areas. 
  • Carry out any additional cleaning before disinfecting process.
  • Leave surfaces to dry.
  • ULV Fogging - disinfect surfaces with EPA approved disinfectant.
  • Spray and cover all high-touch surfaces. 
  • Spray wall, windows, flat surfaces and floors. 
  • Leave solution as per manufacturers instruction. 
  • After dwell time wipe high-touch points with disposable clothes.
  • Non-porous surfaces cleaned and disinfected.
  • Site is closed during high-risk cleaning
  • Clients are informed of the designated re-entry period.

Disinfectants with 62-71% ethanol, 0.5% hydrogen peroxide or 0.1% sodium hypochlorite (bleach) can "efficiently" inactivate coronaviruses within a minute, according to this research.

Hydrogen Peroxide in ULV Fogging is used to eradicate and destroy infectious bacteria including all forms of bacterial spores, fungi, fungal spores and viruses. 

Just like other oxygen-based bleaches, hydrogen peroxide breaks down safely into water and oxygen and is a more environmentally-friendly bleach than sodium hypochlorite.

This includes areas frequently touched and used. High-traffic areas - those with more foot traffic and activity in the facility.
Some examples are door handles, push plates, light switches, stair railings, lifts, reception desk, printer screens, alarm panels, shared tables, water dispensers, kitchen surfaces, shared appliances, restroom surfaces, toilet flush buttons, taps, soap dispensers, etc.

ULV equipment is designed to produce very small droplets (20-80 microns), thus ensuring even coverage. Droplet size will increase as the flow rate is increased. This characteristic makes them useful for applying disinfectant and chemicals used for coating insides of heat ducts or other surfaces.

ULV fogging disinfects is used to kill human coronavirus both on surfaces and droplets suspended in the air. 

Other benefits of ULV fogging:
  • Prevent cross-contamination of control areas such as clean rooms and manufacturing areas.
  • Ensures best surface coverage and for disinfecting industrial facilities, large space and complex equipment.

STOP COVID-19 - With the right cleaning procedures, social distancing and a good standard of health hygiene, we can all contribute to ensure a safe environment and reduce the spread of COVID-19 in New Zealand.
