The Hidden Air Quality Problem in Your Office: What Your Cleaning Products Are Releasing Into the Air

When we talk about air pollution in India, we usually look outside. We think about traffic, construction dust, industrial emissions, and smog. But there is another air-quality problem that can be sitting inside the very building where employees spend eight, nine, or even ten hours a day. Your cleaning routine. The floor may be spotless. The washrooms may be shining. The reception area may have that familiar “fresh” fragrance after housekeeping finishes. Everything looks clean. Everything smells clean. But clean surfaces do not automatically mean clean air. Depending on the products being used, cleaning itself can introduce volatile organic compounds (VOCs), fragrances and other chemical pollutants into indoor environments. The World Health Organization has noted that indoor VOC concentrations can often be substantially higher than outdoor concentrations, with studies reporting indoor levels between two and twenty times those outdoors. Cleaning products, deodorizers, floor-care products and toilet cleaners are among the potential sources.

What exactly are VOCs?

VOC stands for volatile organic compounds. In simple terms, these are chemicals that can evaporate into the air at room temperature. Your office can contain more sources of VOCs than you might think. Paints, adhesives, furniture, carpets, air fresheners, fragrances, printing equipment and cleaning products can all contribute to indoor chemical emissions. Cleaning products deserve particular attention because they are deliberately introduced into occupied spaces. Floor cleaners are applied across large areas, surface sprays are used repeatedly on desks and workstations, glass cleaners are sprayed throughout the day, and washroom products may continuously release fragrance or other chemicals into the air. This creates an uncomfortable irony. We clean the office because we want a healthier and more comfortable environment. But depending on what we use, the cleaning process itself can temporarily increase chemical exposure indoors.

The “clean smell” is not necessarily a clean-air signal

One of the biggest misconceptions in commercial cleaning is that a strong fragrance means a space has been cleaned properly. We have become accustomed to associating lemon, floral, pine or “fresh” smells with hygiene. But fragrance is not proof of cleanliness. It is simply a sensory experience. Many conventional cleaning products contain combinations of solvents, surfactants, disinfectants and fragrance ingredients. Some fragranced compounds can also react with substances already present in indoor air and create secondary pollutants. Research into cleaning-product emissions has found that ingredients such as terpenes can participate in indoor chemical reactions that produce substances including formaldehyde and particulate matter. That means when someone walks into a recently cleaned office and says, “Wow, it smells so clean,” there is another question worth asking “What exactly are we smelling?”

Look at the floor beneath your feet

Think about a typical commercial building. Every morning, housekeeping teams may clean thousands of square feet of flooring before employees arrive. Corridors, reception areas, cafeterias, meeting rooms, lobbies and washrooms may all be treated with cleaning chemicals. A product that is used once in a home is used repeatedly and at much larger volumes in a commercial building. Over time, that makes product selection much more important. Depending on the formulation, conventional floor cleaners can contain solvents, fragrances, surfactants and other ingredients that may contribute to indoor emissions. Research examining cleaning products has detected compounds such as 2-butoxyethanol, isopropanol and toluene among emissions from products tested.

This does not mean that every conventional floor cleaner is harmful or that every VOC automatically creates a health problem. The point is much simpler facility teams should know what they are introducing into the indoor environment, how frequently they are using it, and whether every ingredient is actually necessary.“Green” on the label should not be the end of the conversation. Procurement teams should be asking more specific questions Is the product VOC-free? Does it contain synthetic fragrance? Does it contain chlorine or bleach? Does it rely on petroleum-based solvents? Does the supplier provide transparent ingredient and safety information?

Surface sprays are another overlooked source

Now think about how surface cleaning happens in an office. Spray the desk. Wipe the desk. Spray the workstation. Wipe the workstation. Spray the glass. Wipe the glass. Move to the next area. Then repeat the process across hundreds or thousands of surfaces. Cleaning activities can change indoor concentrations of VOCs and particulate matter depending on the products used, the application method and the ventilation conditions. For housekeeping staff, the issue can be even more important because they experience repeated exposure as part of their occupation. Research on occupational cleaners has found associations between cleaning-product exposure and respiratory health outcomes, including asthma. This does not mean that every cleaning product causes respiratory illness. Health outcomes are influenced by many factors. But it does mean that cleaning chemicals should be considered an occupational and indoor-air-quality issue, not simply a housekeeping purchase.

And then there is the washroom

Commercial washrooms are often where the “clean smell” becomes particularly noticeable. Walk into an office washroom and you may find urinal blocks, toilet cleaners, disinfectant sprays, air fresheners, deodorizer blocks and fragrance dispensers all operating within the same relatively enclosed environment. Some traditional restroom deodorizer products have used para-dichlorobenzene, a volatile chemical that can enter indoor air. Other products rely heavily on fragrances to mask unpleasant smells. And this brings us to an important distinction Are we eliminating the source of the odour, or are we simply covering it with another smell? Those are two very different approaches. If a washroom has a persistent odour because of urine deposits, organic residue, drains or poor cleaning practices, continuously adding fragrance does not necessarily solve the underlying problem. It can simply make the air smell like chemicals and odour at the same time. A better approach is to address the source.

What does this mean for employees?

Indoor air quality is not just an environmental conversation. It is a workplace conversation. Employees spend a significant part of their day inside offices, commercial buildings, hospitals, schools, malls and other enclosed environments. Cleaning-product exposure, particularly among people who work with these products frequently, has been associated with respiratory symptoms and other health effects. For HR teams, this connects directly to employee wellbeing. For facility managers, it connects to cleaning protocols, housekeeping practices and procurement. For sustainability teams, it connects to healthier materials and responsible chemical management. And for ESG leaders, it raises a broader question Does our sustainability strategy consider the people who actually occupy the building? A building cannot truly claim to put people at the centre of sustainability if its cleaning strategy ignores what is being introduced into the air around them.

What about indoor-air regulations in India?

India has established national ambient air-quality standards and extensive systems for monitoring outdoor air pollution. Indoor air is different. A commercial building is a controlled environment, and its air quality is influenced by ventilation, occupancy, HVAC operation, building materials, maintenance practices and the products used inside the building. India does have standards and green-building frameworks that address aspects of indoor air quality. For example, IGBC's Green Interiors framework includes TVOC monitoring as part of its indoor-air-quality requirements. The bigger challenge is that indoor-air-quality management still requires significant action at the building level. Facility teams cannot simply look at an outdoor AQI number and assume that the air inside the building is healthy. Ventilation matters. HVAC maintenance matters. Occupancy matters. Building materials matter. And yes, the chemicals used during cleaning matter too.

The answer isn't to stop cleaning

Obviously, commercial buildings cannot stop cleaning. The answer is to rethink what we clean with and how we clean. A smarter commercial cleaning strategy begins with source control. Instead of choosing products simply because they clean quickly or leave a strong fragrance, procurement teams can start evaluating products based on their emissions, ingredients and impact on indoor environments. The next step is smarter application. Using the minimum effective quantity, following correct dilution instructions and avoiding unnecessary aerosolisation can all help reduce chemical exposure. Intensive cleaning can also be scheduled when fewer occupants are present, wherever practical, while maintaining appropriate ventilation. Most importantly, facility teams should stop treating smell as a measurement of cleanliness. A strong fragrance is not an indoor-air-quality certificate. If an area repeatedly smells bad, the first question should be What is causing the odour?

A different approach: bio-enzymatic cleaning

This is where bio-enzymatic cleaning can offer a different way forward. Zerodor CARE is built around a bio-enzyme and plant-based cleaning approach designed for people who want effective cleaning without unnecessarily loading indoor spaces with harsh chemical ingredients. Instead of relying on synthetic fragrance to create the perception of freshness, CARE focuses on addressing organic residues and the sources that contribute to stains and odour. The CARE range is designed without synthetic fragrances, VOCs, bleach, chlorine and petroleum solvents. The philosophy is straightforward don't just make the building look clean. Make the cleaning process cleaner too.

Bio-enzymes help break down organic residues that can contribute to stains and odour. This makes the approach particularly relevant to high-use commercial environments where cleaning is happening repeatedly throughout the day. For facility teams, CARE is therefore not simply another “green cleaning product.” It can become part of a broader strategy to rethink commercial cleaning around clean surfaces, cleaner chemistry and better indoor-air practices.

Imagine a different cleaning protocol

Imagine walking into an office after housekeeping has finished. The floors are clean. The washrooms are clean. The workstations are clean. But there is no overwhelming chemical fragrance announcing that cleaning has taken place.Instead of masking odours, the cleaning process has addressed their source. Instead of using unnecessary chemical ingredients, the facility has moved toward bio-enzymatic alternatives. Instead of judging cleaning performance by smell, the facility team is thinking about what is actually happening to the indoor environment. That is a very different definition of clean. And it is one that more commercial buildings should start considering. Because sustainability should not stop at saving water, reducing electricity consumption or recycling waste. It should also include the chemistry we introduce into the spaces where people work every day.

Clean should not have to smell like chemicals

For years, commercial cleaning has been judged by three simple questions:

Does it look clean?

Does it feel clean?

Does it smell clean?

Maybe it is time to add a fourth Does the cleaning process protect indoor air quality? The next time your office smells strongly of “freshness” after housekeeping, pause for a moment.

Don't just ask, “Is the office clean?”Ask:“What did we put into the air to make it smell clean?That question could change the way your building cleans. And for organisations looking to make that change, Zerodor CARE offers a bio-enzymatic, zero-VOC approach to commercial cleaning helping businesses rethink what clean can actually mean.Clean surfaces.
