The Science

What Is QAC Disinfection?

Quaternary Ammonium Compounds (QAC) are a class of broad-spectrum disinfectants widely used in healthcare, food processing, and commercial cleaning. They work by disrupting the cell membranes of bacteria and the lipid envelopes of viruses, destroying them rapidly and effectively.

Our professional-grade QAC formulations are non-corrosive, non-staining, and safe for use on virtually all indoor surfaces. They leave no harmful residue and are safe around people and pets once dry.

Combined with our professional application equipment — including electrostatic sprayers for even coverage — QAC disinfection reaches every surface, including hard-to-reach corners and crevices.

Common Questions

Deep Disinfection FAQs

What is QAC-based deep disinfection?
QAC stands for Quaternary Ammonium Compound — a class of broad-spectrum disinfectant proven effective against bacteria, fungi, and many viruses including enveloped coronaviruses. Our formulation kills bacteria within 1 minute and deactivates coronaviruses within 30 seconds of contact, making it suitable for fast-turnaround commercial cleans.

When should I use deep disinfection instead of regular cleaning?
Use deep disinfection after a confirmed illness in your space (covid, flu, gastroenteritis), before reopening a long-closed venue, ahead of large events in F&B and hospitality, on a recurring schedule for clinics and gyms, or any time you need a documented, lab-grade hygiene treatment.

Is the disinfectant safe for food premises, kitchens, and clinics?
Yes. The QAC formulation is approved for use in food-handling environments and healthcare settings when applied per protocol. We coordinate with your operations team on dwell time and surface re-wipe procedures so you can reopen safely.

How long does the treatment take?
A typical office floor or restaurant can be completed in a few hours; childcare centres, schools, and clinics are often scheduled overnight or on weekends to avoid downtime.

Do I need to evacuate during treatment?
Yes, the area being treated should be unoccupied during application. Re-entry is safe after the standard ventilation and dwell period (typically 1–2 hours).

Can I combine deep disinfection with antibacterial coating?
Yes — and we recommend it for high-traffic environments. Deep disinfection provides immediate microbial knockdown; antibacterial coating gives ongoing protection between cleans. Many of our clinic, school, and gym clients schedule them as a package.
