Office Chair and Upholstery Deep Cleaning: The Cleaning Task Most Offices Forget

Most offices have a cleaning routine that covers the obvious things: floors are vacuumed, desks are wiped, bins are emptied, and bathrooms are kept stocked and sanitary. But there’s one surface that almost every employee touches every single day and that rarely gets a second thought: the office chair.

In short: office chairs absorb sweat, skin cells, dust, and spills into their fabric every day, and daily office cleaning does not remove what’s trapped beneath the surface. A professional upholstery deep clean, done every six to twelve months depending on use, is the only way to properly remove it.

This article explains why office chairs get overlooked, what actually builds up in the upholstery over time, how often a deep clean is worth scheduling, and what the process typically involves.

Why Office Chairs Get Left Out of the Cleaning Routine

Daily and weekly office cleaning is built around visible cleanliness. A cleaner vacuuming a carpet, wiping a desk, or polishing a glass door produces an immediate, visible result. A chair, by comparison, looks clean from a distance even when it isn’t.

Fabric upholstery doesn’t show dirt the way a hard surface does. Dust, skin cells, and body oils settle into the weave of the material rather than sitting on top of it, so a chair can look perfectly presentable while still holding months of accumulated grime. Because there’s no obvious visual cue prompting attention, chair cleaning tends to fall off the standard office cleaning checklist entirely, and is usually only addressed reactively, after a visible stain or a bad smell forces the issue.

What Actually Builds Up in an Office Chair

An office chair is in near-constant contact with a person for eight or more hours a day, five days a week. Over months and years, that adds up. The main things that accumulate in office chair upholstery include:

Sweat and body oils, which soak into the fabric fibres and can cause both odour and gradual discolouration.

Dead skin cells, which build up in soft furnishings in the same way they do in mattresses and carpets

Dust and airborne particles, which settle into fabric far more readily than onto smooth, wipeable surfaces.

Food and drink spills, from the fairly common habit of eating lunch or having a coffee at a desk.

Allergens, including dust mites, which thrive in soft, undisturbed fabric.

None of this is unique to any one office. It’s simply the natural result of a fabric surface being used daily without ever being deep cleaned. Research into indoor microbiomes backs this up more specifically. A study of classroom environments, published in the journal Microbiome and covered on BioMed Central’s research blog, found that chair seats specifically harboured bacteria linked to human contact, while desks carried a different set of skin and oral microbes. In other words, chairs and desks each build up their own distinct microbial footprint over time, simply through everyday use, even when a space looks tidy and clean.

Does Daily Office Cleaning Cover This?

Short answer: no. Daily and weekly office cleaning is designed to maintain hard surfaces, floors, and general tidiness. It does not include deep-cleaning soft furnishings like chairs, because that requires different equipment (typically water injection / extraction method) and considerably more time per item than a standard clean allows for.

This is the same reason carpets need periodic deep cleaning on top of regular vacuuming: surface-level cleaning removes what’s visible, but it can’t reach what’s embedded in the fibres. Office chairs work the same way, just on a smaller, more personal scale.

How Often Should Office Chairs Be Deep Cleaned?

There’s no single number that applies to every office, but a reasonable general guideline is:

High-use chairs (shared workstations, hot-desking setups, call centres, reception areas): every 4 to 6 months

Standard individual office chairs: every 6 to 12 months

Light-use or occasional chairs (meeting rooms, boardrooms): once a year is usually sufficient

A few situations warrant cleaning sooner than a fixed schedule would suggest: after a spill, when a chair changes hands between employees, if anyone in the office has allergies or asthma, or simply when a chair starts to look or smell used, regardless of how long it’s been since the last clean.

What Does a Professional Office Chair Deep Clean Involve?

A professional upholstery deep clean is a different process from a quick wipe-down or a vacuum with an upholstery attachment. It typically involves:

Inspection, to check the fabric type and identify any existing stains that may need pre-treatment

Pre-treatment, applying a solution to loosen embedded dirt, oils, and stains before extraction

Water injection and extraction cleaning, which flushes out dirt, allergens, and residue from deep within the fibres, rather than just moving it around on the surface

Natural Drying, since fabric holds moisture, and chairs generally need a few hours to dry fully before being used again. Air movers and blowers are an option to speed up drying time. Exposure to the sun and warmer weather can also speed up drying times significantly.

This is the same underlying method used for carpet and mattress deep cleaning, adapted for the smaller scale and different fabric types found in office seating.

Is It Worth Deep Cleaning Office Chairs If the Rest of the Office Is Cleaned Daily?

Yes. Daily cleaning and periodic deep cleaning solve two different problems. Daily cleaning keeps a workspace presentable and hygienic on the surface. Deep cleaning addresses what accumulates over time regardless of how consistent the daily routine is. Skipping the deep clean doesn’t just mean grubbier chairs; over time, embedded dirt and oils can also shorten the working life of the upholstery itself, meaning chairs need replacing sooner than they otherwise would.

For offices that already have a contract cleaning arrangement in place, adding periodic chair and upholstery deep cleaning is usually a straightforward extension of the existing service, rather than a separate undertaking altogether.

Frequently Asked Questions

How often should office chairs be professionally cleaned?

Most standard office chairs benefit from a deep clean every 6 to 12 months, with high-use or shared chairs needing attention more frequently, closer to every 4 to 6 months.

Can office chairs be cleaned without removing the fabric?

Yes. Professional upholstery cleaning is done in place using water injection and extraction, so chairs don’t need to be dismantled or have their covers removed.

Does deep cleaning damage office chair fabric?

No, when done correctly. Professional cleaners assess the fabric type first and use appropriate methods and solutions, which is safer for the material than harsh DIY spot-cleaning products.

Is chair cleaning included in standard contract cleaning?

Not usually. Daily and weekly contract cleaning covers surface-level tasks like floors, desks, general tidiness and hygiene. Upholstery deep cleaning is a separate, periodic service, though many providers, including weClean, offer it as a discounted add-on for existing contract clients.

weClean provides ongoing contract cleaning for offices, body corporates, and apartment complexes across Cape Town, along with once-off deep cleaning for carpets, upholstery, and mattresses. Contract clients can add office chair and upholstery deep cleaning at reduced rates. Get in touch on 021 802 6450/1 or info@weclean.co.za for a no-obligation quote.
