Deep Disinfection Services in Singapore — QAC Fogging & Sanitisation
Our deep disinfection service in Singapore combines professional-grade QAC chemistry with ULV fogging and electrostatic spraying to sanitise offices, schools, clinics, restaurants, and HDB homes after confirmed illness, events, or scheduled hygiene resets. The formulation kills 99.9% of common bacteria within a minute and deactivates enveloped viruses, including coronaviruses, in 30 seconds of contact.
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.

ULV Fogging & Electrostatic Disinfection Methods We Use
Different spaces need different application methods. Our Singapore team uses the right combination for your environment — and tells you exactly which during the free inspection.
ULV (Ultra-Low Volume) Fogging
Creates a micro-droplet mist that reaches open floor areas, overhead ducting, and hard-to-wipe corners. Ideal for large offices, schools, warehouses, factories, and any space where uniform coverage beats surface-by-surface application.
Electrostatic Spraying
Charges the QAC solution so droplets wrap around chairs, equipment, electronics, and complex furniture rather than just falling onto horizontal surfaces. Ideal for office fit-outs with lots of equipment, gym floors, and classrooms.
Manual Surface Wipedown
For high-touch points that need direct contact — door handles, keyboards, shared remotes, restroom fittings. Pairs with fogging or electrostatic for a complete sanitisation services Singapore engagement.
Every ULV fogging Singapore job is scoped after the free site inspection — we choose the method that gives the best pathogen coverage for your floor plan, surface mix, and downtime constraints.
Office Disinfection in Singapore
Office disinfection in Singapore covers CBD towers, co-working spaces, and suburban business parks — hot-desking, shared meeting rooms, canteens, and restrooms are all high-transfer zones. We schedule commercial disinfection overnight or across the weekend so business operations are not interrupted.
Common triggers: a confirmed illness on the floor, a new team moving in, quarterly hygiene resets for insurance compliance, pre-opening after a long vacancy, or post-event deep clean after a large conference or company off-site.
Every office deep disinfection engagement ends with a written service report — chemistry, method, scope, timestamp — suitable for HR, facility, and insurance records.
Scope we cover
- •Open-plan workstations and hot desks
- •Meeting rooms, phone booths, quiet pods
- •Pantries, breakout areas, coffee stations
- •Lift lobbies, reception, waiting areas
- •Restrooms and staff facilities
- •Server rooms and telecom cabinets (non-fogging approach)
School, Childcare & Clinic Disinfection
Environments where vulnerable populations — children, the elderly, the immunocompromised — spend the most hours need the most defensible hygiene protocols.
Schools and Kindergartens
School disinfection across MOE-aligned institutions, international schools, and tuition centres. Scheduled during term breaks or after a confirmed outbreak. Covers classrooms, corridors, restrooms, canteens, and shared play areas.
Childcare Centres (ECDA)
Childcare disinfection for ECDA-licensed operators. Application timed around operating hours, with full chemistry and dwell-time documentation for compliance files. Common trigger: HFMD outbreaks and seasonal flu.
Clinics and Dental Practices
Clinic disinfection suitable for MOH-regulated settings. Consultation rooms, reception, waiting areas, and shared equipment. QAC chemistry compatible with standard healthcare hygiene protocols.
For ongoing surface protection between disinfection visits — highly recommended in schools, childcare, and clinic environments — add antimicrobial coating for schools, childcare, and clinic surfaces.
Restaurant, F&B & Hotel Deep Cleaning
SFA-regulated food premises and hospitality operators run tight schedules — deep disinfection fits around service, not the other way around.
Restaurants and Cafés
Restaurant deep cleaning Singapore covers kitchens, cold rooms, dining floors, POS zones, and restrooms. QAC chemistry is approved for food-handling surfaces when applied with correct dwell and rinse procedures.
Hawker Stalls and Central Kitchens
SFA compliance-aware sanitisation services Singapore for hawker operators, food courts, and central production kitchens. Post-norovirus or post-inspection remediation is a common trigger.
Hotels and Serviced Apartments
Hotel disinfection for guest rooms after extended-stay departures, post-illness resets, and seasonal hygiene refreshes. Coordinated with housekeeping so check-in schedules are not affected.
Retail and Malls
Retail disinfection for fitting rooms, POS counters, restrooms, and back-of-house storage. Scheduled overnight or before opening so merchandise and customer traffic are not impacted.
Home Disinfection Services in Singapore (HDB, Condo, Landed)
Home disinfection Singapore covers every property type — same QAC chemistry, same documented outcomes, sized to the home.
HDB flats and BTO units
HDB disinfection after a household illness, returning travellers, preparing for newborns, or between tenants in rental units. 2–4 hours for a typical 4-room HDB.
Condos, landed homes, and GCBs
Larger homes are sized by floor area and surface density. We can focus on the affected area (e.g. one bedroom after an illness) or treat the whole home for a seasonal reset.
For newly renovated homes, bundle disinfection with formaldehyde removal for your newly renovated home — one visit, both problems handled.
COVID-19 & Post-Illness Disinfection
Rapid-booking disinfection for the real-world illness scenarios Singapore offices, schools, and homes face most often.
