How soon can we re-enter the premises after disinfection?

Re-entry timing depends on the disinfectants used and the application method. For most treatments, premises can be re-entered within 30 to 60 minutes after treatment is complete and the space has been adequately ventilated. The specific re-entry window will be confirmed at the time of engagement.

Are the disinfectants used safe for children?

Nanotech Cleaning uses non-toxic, non-corrosive disinfectants across all residential and childcare environments. For childcare centres and schools, fragrance-free agents are selected based on the surfaces and environment being treated.

Do you offer emergency or same-day disinfection during an HFMD outbreak?

Same-day disinfection response is available for confirmed HFMD cases in childcare centres, schools, and other affected environments. Contact us via WhatsApp to arrange an urgent appointment.

Is your disinfection service NEA and MOH compliant?

Nanotech Cleaning is NEA-licensed (Licence No. NEA241725/9998K/C2/R01) and bizSAFE 3 certified. Disinfection protocols are aligned with MOH Infection Control Guidelines applicable to schools, childcare centres, and commercial premises.

What is the difference between regular cleaning and disinfection?

Professional cleaning makes a space clean; disinfection makes a space safe. The latter eliminates the pathogen load that persists on surfaces after cleaning. In environments with confirmed or suspected exposure to a pathogen, disinfection is the appropriate response; cleaning alone is not sufficient.

Can disinfection be scheduled outside operating hours?

Nanotech Cleaning operates seven days a week from 9am to 11pm, including weekends and public holidays. After-hours scheduling is standard practice for schools, offices, and facilities that cannot accommodate treatment during operating hours.

Do you provide a service report or certificate after each session?

A service report is provided at the completion of every disinfection engagement, covering the scope of work, areas treated, agents used, and completion status. It can be used for internal records, regulatory reporting, or communication with relevant stakeholders.

Do you serve childcare centres, schools, and commercial premises islandwide?

Nanotech Cleaning provides disinfection services across Singapore for childcare centres, schools, offices, retail spaces, and other commercial environments. Contact us via WhatsApp to discuss your requirements and arrange a site assessment.

NEA-Compliant Disinfection Service in Singapore

NEA-compliant disinfection is not a higher-end version of a regular clean. It is an entirely different process: specific disinfectants, defined application methods, controlled contact times, and a structured sequence that accounts for how pathogens spread across a space.

Nanotech Cleaning's disinfection service is built around these requirements, applied across childcare centres, schools, offices, and commercial facilities where the risk of surface transmission is highest.

Standard cleaning removes visible dirt and surface residue. What it does not remove is what lingers on surfaces after cleaning: the viruses and bacteria that spread infection in shared environments even when a space looks clean.

Viruses can survive on surfaces: Enteroviruses linked to HFMD can survive on hard surfaces for up to seven days, while influenza and other respiratory pathogens remain viable on high-touch surfaces for hours to days after contamination.
High-touch points spread infections rapidly: Door handles, lift buttons, escalator railings, and shared equipment carry a high pathogen load in busy environments. Standard cleaning does not eliminate what accumulates at these points.
Childcare environments are high-risk: Young children share toys, mats, feeding equipment, and bathroom facilities in close proximity, and their immune systems are still developing, so infections that an adult's body might contain more readily can take hold faster and spread further in a childcare setting.
Improper cleaning may not eliminate pathogens: Not all disinfectants are effective against all pathogens. Using the wrong product, or not leaving it on the surface long enough to work, can leave a space contaminated even after a thorough-looking clean.
Asymptomatic transmission: Infected individuals can spread pathogens before symptoms appear, which means transmission risk exists in premises that appear unaffected.

Why Proper Disinfection Is Critical

Our NEA-Compliant Disinfection Process

Nanotech Cleaning's disinfection process follows the structured sequence set out in NEA guidelines for non-healthcare settings: general waste containment first, then hard surfaces, upholstered furnishings, and floors, followed by waste disposal. This sequencing is intended to minimise cross-contamination between treated and untreated areas and to prevent contaminated material from being reintroduced onto a cleaned surface.

Pre-treatment assessment

The premises are evaluated for surface types, high-touch zones, access constraints, and any areas requiring specific attention before treatment begins.

ULV fogging

Ultra-low-volume fogging disperses disinfectant as a fine mist that reaches surfaces, air gaps, and areas that manual treatment alone cannot efficiently reach.

Dwell time compliance

Disinfectant contact times are observed as specified by the manufacturer and NEA guidelines before surfaces are wiped and the space is released for re-entry. Adequate ventilation is maintained throughout and after treatment.

Manual high-touch surface wipe-downs

Door handles, switches, lift buttons, escalator railings, shared equipment, and restroom fixtures are treated with a steady clean-to-dirty wiping motion, using a disinfectant selected for the pathogen present and applied at the correct concentration.

Electrostatic spraying

The disinfectant is given a light electric charge as it leaves the sprayer, so it wraps around and clings evenly to whatever it lands on, reaching the sides and undersides of objects that a standard spray tends to miss.

HEPA-filter vacuuming

Where floor vacuuming is required, only vacuums equipped with HEPA filtration are used, consistent with NEA guidance for infectious disease environments.

We go beyond visual cleanliness to achieve up to 99.99% elimination of viruses and bacteria, helping to break the chain of infection. This is especially important for diseases like HFMD and measles, which spread rapidly in environments where shared surfaces are not adequately treated. Measles is among the most contagious of the vaccine-preventable diseases; HFMD circulates year-round in Singapore's climate.

Nanotech Cleaning's protocols align with NEA Guidelines and MOH Infection Control Guidelines applicable to schools and childcare centres, with treatment methods and agents matched to the requirements of each environment.

Environment Sanitisation Regime

Multi-Disease Hygiene Protocols

Our protocols are designed for today’s evolving health landscape, addressing pathogens linked to:

HFMD: A highly contagious viral infection that spreads fast in children's environments through both direct contact and contaminated surfaces.
Mpox: A viral infection spread through close contact, requiring thorough disinfection of surfaces, fabrics, and shared items in affected areas.
Measles: One of the most contagious viruses known, spread through the air and able to linger on surfaces after an infected person has left.
Influenza and respiratory illnesses: Seasonal viruses that spread quickly in crowded, enclosed spaces through both the air and frequently touched surfaces.
COVID-19: A respiratory virus spread through the air and contaminated surfaces, still relevant in settings with high footfall.
Hantavirus and related pathogens: Viruses associated with rodent contamination that require specialist protocols when exposure is confirmed or suspected.

A childcare centre is one of the harder environments to disinfect properly. Infections move through it quickly, the surfaces that need treating are used constantly throughout the day, and the disinfectants have to be safe for the children who will be back in the room within hours.

Nanotech Cleaning provides disinfection services for childcare centres using non-toxic, non-corrosive, and fragrance-free disinfectants suited to spaces where children are present. Treatment covers high-touch surfaces and the contact points specific to a childcare setting, including:

Shared toys and play equipment
Milk preparation areas and feeding surfaces
Bedding, cots, and rest area fittings
Potty chairs and bathroom fixtures
Table surfaces, chairs, and classroom materials
Diaper changing areas and family room facilities

Scheduling is arranged to take place before children arrive or after they leave, keeping disruption to the centre's daily programme to a minimum.

Childcare Centre Disinfection in Singapore

School Disinfection Service in Singapore

A school packs a lot of people into shared spaces for hours at a time, and infections move easily between classrooms, canteens, and common areas once they take hold. Daily cleaning keeps a school looking tidy, but it does not remove what builds up on shared surfaces over the course of a full school day.

Nanotech Cleaning provides disinfection services for primary and secondary schools, as well as other educational institutions, covering the areas where students and staff spend most of their time. Treatments are scheduled around the school calendar and carried out on weekends, during school holidays, or after hours so that teaching is not interrupted.

Where documentation is required for MOE reporting or internal records, Nanotech Cleaning provides a service report upon completion, detailing the areas treated, the agents used, and the scope of work carried out.

When HFMD turns up in a childcare centre or school, it needs a fast, focused response. The viruses behind it, mainly Coxsackievirus A16 and Enterovirus 71, can survive on hard surfaces for up to 7 days, and a routine cleaning will not reliably eliminate them.

MOH's guidance for HFMD disinfection recommends a 1:49 dilution of household bleach for general surfaces, left on long enough to work, then wiped. For anything contaminated by blood, stool, or other bodily fluids, a stronger 1:9 dilution is specified.

Nanotech Cleaning offers same-day response for confirmed HFMD cases, using agents and dilutions in line with MOH guidance, and covering all affected and high-risk surfaces across the premises. Once the work is done, a service report outlining what was treated and how it was done is provided, ready to share with parents, management, or the authorities if needed.
