Most people wipe down their desk, clean their keyboard, and forget completely about the chair they sit in for eight hours a day. Mesh office chairs do a great job of keeping you cool and supported, but that same open-weave design that lets air through also traps dust, skin cells, hair, and the occasional coffee splash. Over time, a neglected mesh ergonomic chair looks dull, smells off, and can actually affect how well the mesh supports your back. This guide walks you through exactly how to clean a mesh office chair safely, what products to avoid, and how to keep it in good shape long term.
Whether you own a Sihoo M57, a Doro C300, or a Doro S300, the cleaning principles are the same. The good news is that mesh is one of the easier chair materials to maintain. You do not need specialist products or professional help. You need about thirty minutes, a few things you likely already have at home, and a method that will not damage the fibres.
Why Mesh Chairs Need Different Care to Fabric or Leather
How Mesh Fibres Trap Dirt Differently
Fabric chairs absorb spills and stains into their padding. Leather chairs sit on the surface and wipe off relatively easily. Mesh sits somewhere in between, and the difference matters when you are cleaning it.
Mesh is made from interwoven polymer fibres, typically polyester or nylon, stretched across a frame under tension. That tension is what gives the chair its support. When dust, sweat, and skin oils accumulate in the weave, they form a fine layer of grime that gradually reduces airflow and can cause the mesh to lose some of its responsiveness over time. The fibres themselves are durable, but they are also susceptible to fraying if you use the wrong tools or scrub too aggressively.
The other consideration is the foam or padding underneath the mesh seat. Most mesh chairs have a thin cushioned base beneath the mesh seat pan. If you oversaturate the mesh during cleaning, that moisture can seep into the foam, which takes a long time to dry and can develop a musty smell if it stays damp. Controlled moisture is the key principle in everything that follows.
What Happens If You Ignore It
A chair that has not been cleaned in six months or more will show it. The mesh discolours around the areas that contact your back and the back of your thighs. Body oils accumulate and give the mesh a slightly greasy feel. The gap between the mesh fibres narrows with compacted dust, which restricts the airflow that makes mesh chairs worth buying in the first place.
Beyond appearance, a dirty chair is a hygiene issue. Research has noted that a standard office chair can harbour significant bacterial buildup when left uncleaned, particularly in warm environments. For shared office chairs, hot-desking setups, or any workspace where multiple people use the same seat, regular cleaning is not optional. It is basic workplace hygiene.
If your chair is already showing signs of wear and you are not sure whether cleaning will be enough to restore comfort, it may be worth reading how to make your office chair more comfortable alongside this guide. Sometimes a clean chair still needs a few setup adjustments to feel right again.
What You Need Before You Start
Safe Cleaning Supplies for Mesh
You don't have to buy anything special. All you need to do a thorough cleaning is:
The most important tool for the dry phase is a vacuum cleaner with a soft brush attachment.
-
Use a soft-bristle brush or an old toothbrush to get rid of stubborn dirt that is stuck in the weave.
-
Two microfiber cloths: one for applying the solution and one for rinsing it off.
-
A few drops of mild dish soap are all you need. Look for a formula that doesn't have any added fragrance and is pH-neutral.
-
Water that is not too hot. Heat can make synthetic fibers weaker or bend them.
-
Spray bottle: not required, but helpful for controlling how much moisture you use
-
A dry towel to pat down with after the wet clean
-
Baking soda is optional and can be used to get rid of smells.
One thing to remember is to always put your cleaning solution on the cloth, not directly on the chair. Spraying liquid directly onto the mesh makes it unevenly wet and could push moisture into the foam below.
Avoid Products That Damage Mesh
This is where most people get into trouble. The temptation to reach for something stronger when a stain is stubborn is understandable, but the wrong product can do permanent damage to the mesh fibres and void your chair warranty.
-
Bleach or bleach-based cleaners — discolour and weaken the polymer fibres
-
Ammonia-based products — strip the natural properties of the mesh and damage the frame finish
-
Strong solvents or degreasers — can dissolve the bonding in the mesh and loosen it from the frame
-
Abrasive powders or scrubbing pads — fray individual fibres permanently
-
Steam cleaners — the heat warps the synthetic mesh and can damage plastic chair components. Despite what some general guides say, steam is not safe on mesh
-
Hairdryers — direct heat shrinks and weakens mesh fibres. Always air dry
-
Heavily fragranced fabric sprays — leave residue in the weave that attracts more dust
If you are unsure about a product, check the care label on the underside of your chair seat. Most chairs carry a cleaning code. "W" means water-based cleaners are safe. "S" means solvent-based cleaners only. If you see "WS", either is fine. If in doubt, mild dish soap and water is always safe on mesh.
How to Clean a Mesh Office Chair Step by Step
Step 1: First, dry clean
Make sure the chair is completely dry before you start. Don't go straight to the wet clean. First, vacuuming and brushing get rid of the loose layer of dust and dirt that would turn into a paste if you added water. That paste is much harder to get rid of and gets deeper into the fibers.
Put the soft brush head on your vacuum and run it over the whole mesh backrest in overlapping passes, first from side to side and then from top to bottom. This makes sure you get every part of the weave. Pay close attention to the seams where the mesh meets the frame. Dust builds up a lot in these places. Do the same thing on the mesh seat.
If your vacuum can't get to the tighter areas around the lumbar support, the armrest joints, or the base of the backrest, use a soft-bristle brush or an old toothbrush to loosen the dirt and then vacuum again. Don't use a brush with stiff bristles. Hard bristles break up the polymer strands, which lowers their tensile strength permanently. This makes the mesh less supportive.
Step 2: Clean Up Stains
Before you do a full wet clean, get rid of any stains that you can see. If you mix a stain treatment that works on a specific type of stain with a general clean, neither will work as well. Get rid of the stain first, then move on to the rest of the chair.
Add about 250ml of lukewarm water to half a teaspoon of mild dish soap. Put a microfiber cloth in the solution and wring it out well. The cloth should be damp, not wet. Gently rub the stain with a circular motion, starting from the outside and moving in. Working outward makes the stain spread even more. Working inward keeps it in check.
For stains that are older or harder to get rid of, let the damp cloth sit on the spot for two minutes before rubbing it gently. A soft toothbrush can help the solution get into the fibers of places like the seat and headrest where it touches them. After treating, use a clean, dry part of the cloth to blot the area and remove the residue. Don't rub. Blotting lifts the stain, while rubbing pushes it in.
If you have coffee or tea stains, act quickly. It's much easier to get rid of fresh stains than dried ones. Use a dry cloth to soak up the liquid right away so it doesn't get into the fiber. Then, use the soap solution as described above.
Step 3: Clean the full mesh thoroughly.
After you treat the stains, you can clean the whole surface. Use the same solution of lukewarm water and mild soap. Wet your microfiber cloth and squeeze it out well. You should be able to run it across your forearm without it dripping.
Use light, even pressure to start at the top of the backrest and work your way down in sections. To make sure you don't miss any strips of mesh, slightly overlap each pass. Between sections, rinse the cloth with clean water so you don't spread the dirt you've just cleaned.
After you've cleaned the whole backrest, use a second cloth that is only damp with plain water to go over the same spots. This step of rinsing is very important. Soap residue left in the mesh attracts dust, so your clean chair will get dirty faster than one that was rinsed well.
Do the same thing to the mesh seat, but be more careful this time. The seat can hold more weight and pressure from the body. You should stay away from too much moisture near the foam padding underneath. The cloth should only be slightly damp.
Step 4: Clean the base, armrests, frame, and castors.
People usually only clean the mesh and not the rest of the chair. The armrests, frame, gas lift column, and castor wheels all get dirty and need to be cleaned often.
Wipe down the armrest pads with a damp cloth and some mild soap. Don't soak the pads if they have foam on top. The plastic or aluminum frame can handle a cloth that is a little wetter. Work into the joints and adjustment mechanisms where dust and skin oils collect.
The wheels that hold the chair up are often the dirtiest part. Hair, carpet fibers, and other debris can get stuck around the wheel axles and make it harder for the chair to roll. Use a toothbrush or a crevice tool to get rid of dirt and debris from around each wheel. Wipe the wheels down with a damp cloth and let them dry before you roll on the carpet again.
You can clean the aluminum base of Sihoo chairs with a cloth that is only a little damp. To keep the finish from getting water spots, dry it right away. You can clean the gas lift column with a clean, dry cloth to get rid of dust and fingerprints.
Step 5: Make sure the chair is completely dry.
Most people make their last mistake when they dry. Being impatient can lead to shortcuts that hurt things. Direct sunlight and hair dryers can both damage synthetic mesh. Heat bends the polymer fibers, makes the tension that holds them up weaker, and can break plastic chair parts. Air drying is the only way to dry things safely.
After cleaning, use a dry towel to pat the mesh down to soak up as much moisture as possible. Next, move the chair to a place with good air flow, like a room with an open window or door. Let it dry completely before you sit on it. This usually takes two to four hours in a room with good air flow. It can take up to twelve hours in a humid place. Don't hurry.
Put a fan on low facing the chair to speed things up. The air flow speeds up drying without adding heat. This is the only safe way to cut down on drying time.
How Often Should You Clean Your Mesh Chair
Weekly Maintenance Routine
A small amount of consistent effort makes a far bigger difference than occasional heavy cleans. The weekly routine takes under five minutes and prevents the gradual buildup that makes the deep clean necessary more than once or twice a year. Give the chair a quick once-over with the soft brush attachment on your vacuum. Focus on the backrest, seat, and the seams where mesh meets frame.
-
Wipe down the armrests and armrest pads with a dry microfibre cloth to remove skin oils and surface dust.
-
Check the castors for any tangled hair or debris and remove it.
That is it. Three steps, five minutes. Done consistently, this keeps the chair looking clean and the mesh performing well between deeper cleans. Even if you have the best ergonomic chair for your back, gaming, or working, if you are not maintaining it, your investment may be put to waste. It’s important to maintain your chair.
Monthly Deep Clean Schedule
Once a month, run through the full five-step process described above. This is when you do the spot stain check, the full mesh wet clean, the frame wipe-down, and the proper air dry. Monthly is the right frequency for most home office users.
If you use the chair for more than eight hours a day, share it with others, work in a warm or humid environment, or eat at your desk regularly, increase the deep clean to every two to three weeks. Offices where multiple staff members share chairs should clean after each rotation or at minimum weekly.
For a full seasonal reset, roughly every three to six months, add a baking soda odour treatment. Lightly sprinkle baking soda across the dry mesh seat and backrest, leave it for thirty minutes, then vacuum it off completely. This neutralises any accumulated body odour without introducing moisture.
Caring for Your Sihoo Chair Specifically
Sihoo Mesh Material Notes
Sihoo chairs use a high-quality breathable mesh across their range. The M57, Doro C300, and Doro S300 all feature mesh that is engineered for both airflow and long-term structural integrity. The mesh is designed to hold its tension and shape under sustained daily use, but like all mesh materials, it benefits from gentle care.
A couple of things specific to Sihoo chairs are worth noting. The Doro C300 features a split backrest design where each side of the mesh flexes independently. When vacuuming, run the brush attachment over both halves individually and pay attention to the central join. Debris can accumulate along the split line.
The Doro S300 has a dual-layer mesh backrest. The outer mesh layer and the inner support structure both benefit from the vacuum dry clean step. Take extra time along the outer edges of the backrest where the two mesh layers meet the frame, as grime tends to settle in these recessed areas.
If you have recently set up your Sihoo chair and want to make sure it is adjusted correctly for your body before doing a clean, this guide on how to properly adjust your ergonomic chair covers the setup steps in detail. A well-adjusted chair also sits more evenly on the castors, which means dust and debris distribute more predictably and are easier to clean.
Warranty and Care Reminders
Sihoo Australia offers a three-year warranty on the M57 and a five-year warranty on the Doro series. Using harsh chemical cleaners, steam, or abrasive tools can damage the mesh, discolour the frame finish, and in some cases affect your warranty coverage. The cleaning method outlined in this guide uses mild soap and water, which is safe for all Sihoo chair materials and will not affect your warranty.
If you notice any changes in mesh tension, loose stitching at the frame edges, or damage to the adjustment mechanisms, contact Sihoo Australia support rather than attempting repairs yourself. Their team can advise on replacement parts or warranty claims. You can reach them at support@sihoo.com.au or 1300 002 580.
For anyone setting up a home office around their chair, these home office design ideas are worth a look. A well-organised workspace tends to stay cleaner because there is less clutter collecting dust near the chair in the first place.
Final Tips to Keep Your Sihoo Chair Looking and Performing Its Best
Cleaning a mesh office chair is not complicated. The basics are simple: vacuum regularly, clean with mild soap and a barely damp cloth when needed, avoid heat and harsh chemicals, and always let it air dry fully. Follow those four principles and your chair will stay fresh and supportive for years.
A few additional habits that make a real difference over time:
-
Keep a microfibre cloth at your desk for quick wipe-downs of the armrests and headrest at the end of the day. This thirty-second habit prevents the slow accumulation of skin oils that causes most of the discolouration.
-
If you eat at your desk, consider a chair cover or desk mat to catch crumbs before they reach the seat. Removing a cover and shaking it out is far easier than vacuuming crumbs out of mesh.
-
Every few months, check the mesh tension on your backrest by pressing it with your hand. If the mesh feels noticeably looser or starts to sag, contact Sihoo support. A sagging backrest provides less lumbar support, and no amount of cleaning will fix that.
-
When the office or home office is being cleaned around you, tilt your chair seat up or move it out of the way so cleaning products used on the floor or desk do not accidentally spray onto the mesh.
If you are reading this guide because your current chair is not comfortable even when clean, it may be time to look at whether it is the right chair for your body and working style. This guide to the best office chairs for long hours of sitting covers what to look for if you are considering an upgrade.
And if you are tall or on the shorter side and have never had a chair properly fitted to your measurements, the ergonomic chair guide for tall people is worth reading alongside this care guide. A chair that fits well and is kept clean is the combination that makes the biggest difference to how your back feels at the end of a long day.

Frequently Asked Questions
General office cleaning costs, including products and services used to maintain chairs and workstations, are typically deductible as business operating expenses. If you bring in a professional cleaning service specifically to deep clean your office chairs, that cost is generally claimable. Consult your accountant for confirmation, as deductibility depends on how the cleaning relates to your business operations and the current ATO guidance for your situation.
Yes. Mild dish soap, lukewarm water, and microfibre cloths are safe across the full Sihoo range including the M57, Doro C300, and Doro S300. The cleaning process is identical across all three models. The only difference is that the Doro C300 has a split backrest that needs attention along the central join, and the S300 has a dual-layer mesh that benefits from extra time along the frame edges. Avoid bleach, ammonia-based products, and steam on all models.
Maintaining a clean and safe working environment is a core obligation under the Work Health and Safety Act. While there is no specific regulation that names chair cleaning, the general duty of care requires employers to provide a safe and hygienic workplace. Dirty chairs that harbour bacteria, allergens, or unpleasant odours in a shared environment can be considered a hygiene risk. Documenting a regular chair maintenance schedule is a practical way to demonstrate that your organisation takes workstation hygiene seriously.
Create a simple maintenance schedule and assign it to a rotating member of the team or include it in your office cleaning contract. Keep a small cleaning kit near the chairs, including a handheld vacuum, two microfibre cloths, and a spray bottle with mild soap solution. The five-step process takes around twenty to thirty minutes per chair for a deep clean. A weekly maintenance vacuum takes under five minutes. For larger offices, consider deep cleaning chairs in batches of five or ten on a rolling monthly rotation.
For chairs in dedicated workstations used by one person, monthly deep cleans are sufficient with weekly maintenance wipes. For shared or hot-desking chairs that rotate between multiple users, clean after each changeover or at minimum weekly. High-traffic chairs in customer-facing or health-related environments should be wiped down daily. The more people sharing a chair, the more frequently it needs attention.
For chairs with a fixed lumbar cushion, wipe around and underneath it with a barely damp cloth. Remove any lumbar cushion that detaches before cleaning the mesh behind it, and clean the cushion separately. For dynamic lumbar supports like those on the Doro C300 and S300, clean the mesh surface the same way as the rest of the backrest. The mechanism itself does not need wet cleaning. Wipe the outside of the mechanism housing with a dry cloth to remove surface dust.
Body odour in a mesh chair is almost always caused by accumulated sweat and skin oils in the fibres. Sprinkle baking soda lightly over the dry mesh, leave it for thirty minutes, then vacuum it off thoroughly. For persistent odour, do a full wet clean with the mild soap solution first, allow the chair to dry completely, and then do the baking soda treatment. Do not use air freshener sprays directly on the mesh. They mask the smell temporarily and leave a residue that attracts more dust.
The mesh or the foam underneath got too wet during the clean and did not dry completely before you used the chair. The moisture trapped in the foam grew mould or bacteria, which causes the musty smell. To fix it, do another clean using a barely damp cloth, then allow the chair to dry for at least twelve hours in a well-ventilated space before using it. Going forward, wring your cloth out more thoroughly during the wet clean and prioritise the air dry step.
Act immediately. Blot the liquid with a clean dry cloth to absorb as much as possible before it penetrates the fibre. Do not rub. Once you have blotted as much as you can, treat the area with the mild soap and lukewarm water solution using a barely damp cloth. Blot again to lift the residue. Then allow it to air dry fully. The faster you respond to a spill, the better the outcome.
No. Direct sunlight applies UV heat that weakens synthetic mesh fibres over time and can warp plastic chair components. It may look like it is drying the chair faster, but it is doing subtle damage in the process. Move the chair to a shaded, well-ventilated area and let it air dry naturally. A fan on low is the only safe way to speed up the process.
