Do Saunas Need to Be Cleaned?
Yes — absolutely. Despite the common misconception that the heat of a sauna sterilises everything inside it, saunas require regular, deliberate cleaning to remain hygienic, safe, and in good condition. The warm, occasionally humid environment of a sauna — combined with the significant sweating that occurs during use — creates conditions that can support bacterial growth, mould development, and unpleasant odours if not managed properly.
The high temperatures of a traditional sauna do reduce bacterial load on surfaces over time, but they don’t eliminate it entirely, particularly in areas with heavy sweat contact like bench surfaces, backrests, and floor slats. Infrared saunas, which operate at lower temperatures, have even less thermal self-cleaning effect and rely more heavily on manual cleaning for hygiene maintenance.
Regular cleaning also protects the sauna’s materials — particularly the wood, which is the most important and most vulnerable component of any sauna cabin. Without proper care, sauna wood can become discoloured, develop mould, absorb persistent odours, and deteriorate structurally over time. A well-maintained sauna can last 15–25 years; a neglected one significantly less.

Does a Sauna Clean You? Pores, Lungs and System
Before diving into how to clean the sauna itself, it’s worth addressing this frequently asked question — because the answer shapes how people think about sauna hygiene generally.
Does a Sauna Clean Your Pores?
Partially yes — and this is one of the genuinely evidence-supported skin benefits of regular sauna use. The heat causes your pores to dilate and your sweat glands to flush outward, carrying with them sebum, dead skin cells, surface debris, and some bacteria from within the pore. This is a form of thermal deep cleansing that topical products alone can’t fully replicate.
However — and this is critical for sauna hygiene — this flushing action only provides the cleansing benefit if you shower immediately after your session. If you let post-sauna sweat dry on your skin without cleansing, the flushed debris (now mixed with bacteria and salt) can be reabsorbed into pores as they close, potentially worsening skin conditions rather than improving them. Always shower after a sauna session.
Does a Sauna Clean Your Lungs?
Sauna use — particularly traditional steam saunas where water is poured on rocks — can temporarily improve respiratory function by loosening mucus in the airways, reducing congestion, and soothing inflamed nasal and bronchial passages. However, the sauna does not “clean” the lungs in a physiological sense — the lungs have their own highly effective self-cleaning mechanisms (mucociliary clearance) that are not directly enhanced by sauna heat. Read our article on sauna for sinus infection for more on the respiratory benefits of heat therapy.
Does a Sauna Clean Out Your System?
The idea of “detoxifying” through sauna sweating is popular but requires nuance. Sweat does contain trace amounts of certain metabolic waste products, heavy metals, and environmental toxins — so there is a modest detoxification component to heavy sweating. However, the kidneys and liver are the primary organs of systemic detoxification, and a sauna’s contribution to this process is supplementary rather than primary. The real cleaning value of regular sauna use is more accurately described as supporting the body’s natural detoxification systems through improved circulation, reduced inflammation, and enhanced metabolic health.
For more on the health benefits of regular sauna use, explore our sauna guides and read our comprehensive article on the benefits of sauna for skin.
How Often Should You Clean a Sauna?
The right cleaning frequency depends on how often your sauna is used and by how many people. Here’s a practical framework.
After Every Session: Quick Wipe-Down
After each use, a quick wipe-down of bench surfaces and backrests with a clean damp cloth removes fresh sweat before it soaks into the wood. This takes 2–3 minutes and dramatically reduces the accumulation of sweat residue that causes discolouration and odour over time. The bench areas that received direct body contact are the priority — armrests, seat surfaces, and foot rests.
Weekly: Thorough Surface Clean
Once a week — or after every 5–7 uses — conduct a more thorough cleaning of all wood surfaces, the floor, the door, the heater surround, and any accessories. This is when you use a wood-safe cleaning solution (covered below) and address any developing stains or odour spots before they become established.
Monthly: Deep Clean
Once a month, perform a comprehensive deep clean that includes sauna rocks (for traditional saunas), heater inspection, ventilation checks, and treatment of any wood that shows signs of mould, darkening, or stubborn staining. This is also a good time to assess whether any components need replacement or professional attention.
Seasonally: Inspection and Treatment
Every few months — particularly for outdoor saunas exposed to changing weather — inspect the exterior cladding, roof, door seals, and structural components. Consider re-treating exterior wood surfaces with appropriate outdoor wood protection products if needed. Read our guide on sauna wood types to understand how different woods require different maintenance approaches.
What to Use to Clean a Sauna
Choosing the right cleaning products for a sauna is important — sauna wood is untreated or lightly treated by design, which means it is more porous and reactive to chemicals than most household surfaces. The wrong products can damage the wood, leave harmful residues that off-gas when heated, or strip the natural properties of the timber.
Safe and Recommended Cleaning Agents
- Warm water: For fresh sweat and light cleaning, warm water with a clean microfibre cloth is the simplest and safest option. No chemicals, no residue, no risk.
- Mild dish soap (diluted): A few drops of gentle, fragrance-free dish soap diluted in warm water is suitable for regular bench and surface cleaning. Use minimally and rinse thoroughly — soap residue left in wood can cause discolouration and odour when heated.
- White vinegar solution: A 1:10 dilution of white vinegar in water is a natural, effective, and safe cleaning and mild disinfecting solution for sauna wood. It cuts through sweat residue, addresses mild mould, and doesn’t leave harmful chemical residues. Allow to dry completely after application. The vinegar smell dissipates as it dries.
- Hydrogen peroxide (3%): Diluted hydrogen peroxide (3% pharmacy grade, diluted further 1:1 with water) is effective against bacteria and mould on sauna wood without the chemical harshness of bleach. It breaks down into water and oxygen, leaving no harmful residue.
- Purpose-made sauna cleaners: Several manufacturers produce cleaning products specifically formulated for sauna wood — these are the safest choice as they are pH-balanced for timber and tested for safety when the surface is subsequently heated.
What Never to Use in a Sauna
- Bleach or chlorine-based products: These are too harsh for sauna wood, can damage the timber, and produce potentially harmful fumes when the wood is subsequently heated.
- Ammonia-based cleaners: Similarly too harsh, leave residues that can off-gas at high temperatures.
- Strong aromatic cleaners or air fresheners: Fragranced chemical cleaners can penetrate wood and release unpleasant or harmful fumes during heating.
- Oil-based cleaners or conditioners: Sauna wood should not be oiled or sealed — the timber is left untreated by design to allow for thermal expansion, contraction, and moisture management. Oil treatments clog the wood’s natural breathing and can cause rancidity and burning smells during use.
- Abrasive scrubbers: Metal or rough abrasive pads damage the wood surface and open up the grain to deeper penetration of sweat and moisture.
Browse our sauna care product range for purpose-made cleaning solutions and wood treatment products safe for regular sauna maintenance.
How to Clean Sauna Wood and Benches
The wood surfaces — particularly the benches — are the most important and most frequently cleaned part of any sauna. Bench surfaces receive direct body contact during every session, accumulating sweat, skin oils, and bacteria with each use.
Routine Post-Session Bench Cleaning
- Allow the sauna to cool to a comfortable handling temperature after your session.
- Using a clean microfibre cloth dampened with warm water, wipe down all bench surfaces in the direction of the wood grain. Work from the top bench down to avoid dripping onto already-cleaned surfaces.
- For any visible sweat stains or discolouration, apply a small amount of diluted white vinegar solution with a cloth, working it into the wood grain with gentle circular motions.
- Rinse the treated area with a clean damp cloth to remove any vinegar residue.
- Leave the sauna door slightly ajar to allow airflow and ensure complete drying before the next session.
Removing Stubborn Sweat Stains From Sauna Wood
Over time, particularly in areas of heaviest use, sweat stains can penetrate the wood and become established. For these stubborn marks:
- Make a paste of baking soda and water and apply it to the stained area.
- Allow to sit for 10–15 minutes then scrub gently with a soft-bristled brush in the direction of the grain.
- Wipe clean with a damp cloth and allow to dry thoroughly.
- For very persistent staining, light sanding with fine-grit sandpaper (120–180 grit) in the direction of the grain can restore the wood surface — sauna wood can be sanded and refreshed multiple times over its lifespan.
Preventing Bench Staining
The most effective approach to bench cleaning is prevention. Always sit on a towel during sauna sessions — this absorbs the majority of sweat before it reaches the wood, dramatically reducing staining and bacterial contamination of the bench surface. A clean towel every session is the single most effective sauna hygiene practice you can adopt.
For more on choosing and caring for sauna wood, read our guide on sauna wood types and explore our sauna timber components if any sections of your benches need replacement.
How to Clean a Cedar Sauna
Cedar is one of the most popular sauna wood choices in Australia and worldwide, prized for its natural aromatic properties, resistance to moisture and decay, and beautiful reddish-brown appearance. Cleaning a cedar sauna requires some specific considerations to preserve these qualities.
Cedar’s Natural Advantages
Cedar contains natural oils — particularly thujaplicins — that give it inherent antimicrobial and antifungal properties. This makes cedar saunas somewhat more naturally resistant to mould and bacterial growth than other wood types. However, this doesn’t mean cedar saunas don’t need cleaning — the natural oils deplete over time, particularly with repeated heat cycling and cleaning, and regular maintenance preserves both the protective properties and the appearance of the wood.
Cleaning Cedar Sauna Wood
The same principles apply as for general sauna wood cleaning — warm water for routine cleaning, diluted white vinegar for deeper cleaning and mild disinfection, and fine sanding for surface refresh when needed. Cedar is particularly responsive to light sanding — after sanding, the fresh wood surface releases the characteristic cedar aroma strongly, essentially refreshing the wood to a near-new condition.
What to Avoid With Cedar
Never use oil-based treatments on cedar sauna wood — cedar already contains natural oils and adding more will cause the surface to become tacky, rancid-smelling when heated, and prone to accelerated darkening. Avoid harsh chemical cleaners that strip the natural oils and leave the cedar looking bleached and dry.
Managing Cedar Darkening
Cedar naturally darkens with heat exposure over time — this is completely normal and not a sign of damage or poor maintenance. The rich, deep brown of aged cedar is considered attractive and is part of the natural character of the material. If you prefer a lighter, fresher appearance, periodic light sanding restores the surface colour effectively.
Read our guide on thermowood vs cedar to understand how these two popular sauna wood choices compare in terms of maintenance requirements, and explore our range of spruce log saunas for traditional sauna options in different wood species.
How to Clean an Infrared Sauna
Infrared saunas require a somewhat different approach to cleaning than traditional saunas, primarily because of the electronic components embedded in the walls and the lower operating temperatures that provide less passive bacterial reduction between sessions.
Key Differences From Traditional Sauna Cleaning
The infrared panels embedded in the walls are the critical difference. These are electronic components that must never be sprayed with liquid, scrubbed directly, or cleaned with wet cloths. Water ingress into infrared panels can cause electrical failure and safety hazards. Always apply any cleaning solution to a cloth first — never spray directly onto surfaces in an infrared sauna.
Step-by-Step Infrared Sauna Cleaning
- Power off and cool down: Always ensure the sauna is switched off at the wall and completely cooled before cleaning. Never clean a hot infrared sauna.
- Wipe bench surfaces: Using a microfibre cloth dampened (not dripping) with warm water or diluted vinegar solution, wipe all bench surfaces in the direction of the wood grain. Wring the cloth thoroughly before applying to wood — excess moisture is the enemy of sauna wood.
- Clean the walls (avoiding panels): Wipe the wooden wall surfaces between and around the infrared panels using the same damp cloth. Work carefully around the panel edges — do not allow liquid to enter the panel frames or seams.
- Wipe the door and glass: Clean the interior of the sauna door with a damp cloth. For glass panels in the door, a diluted vinegar spray on a cloth (not sprayed directly at the glass) works well for streak-free results.
- Clean the floor: See the floor cleaning section below.
- Air dry: Leave the door slightly open after cleaning to allow complete air drying before the next session.
Cleaning Specific Infrared Sauna Brands
For Clearlight saunas, Sunlighten saunas, and Nurecover saunas — the same principles apply across all quality infrared sauna brands. Always check your specific model’s user manual for any brand-specific cleaning recommendations. The core guidance — damp cloth only, no direct spraying, no harsh chemicals — applies universally.

How to Clean a Sauna Floor
The sauna floor receives less direct body contact than benches but accumulates water, sweat drips, and foot traffic with every session. It’s also the area most vulnerable to moisture-related issues — particularly mould and mildew — because water naturally pools and collects at floor level.
Wooden Slat Floors
Most sauna floors feature removable wooden slats or duck boards. These should ideally be removed after each session to allow both the slats and the floor beneath them to dry properly. After each use:
- Remove the slats and lean them against the wall or take them outside to air dry.
- Sweep or wipe the floor beneath to remove debris and standing water.
- For weekly cleaning, scrub the slats with a soft brush and diluted vinegar solution, rinse thoroughly, and allow to dry completely in sunlight if possible before replacing.
Fixed Wooden Floors
For fixed wood floors, sweep after each use to remove debris, then mop with a minimally damp mop using diluted vinegar solution. Never leave standing water on a fixed sauna wood floor — it will penetrate the wood and cause swelling, warping, and mould. Dry thoroughly after mopping and ensure good ventilation.
Tile or Concrete Floors
Non-wood sauna floors (tile or sealed concrete) are easier to clean — mop with diluted vinegar or a mild floor cleaner, paying attention to grout lines where mould can develop. Ensure complete drying before the next use. Read our guide on sauna insulation if condensation on floor surfaces is a persistent issue — it may indicate an insulation problem.
How to Clean Sauna Rocks
Sauna rocks — the stones that sit on the heater and are doused with water to create löyly (steam) — require their own specific maintenance routine. Over time, rocks absorb minerals from water, develop surface deposits, crack from repeated thermal cycling, and can harbour bacteria.
How Often to Clean Sauna Rocks
Sauna rocks should be inspected and cleaned every 1–2 years for home saunas used several times per week, or whenever you notice decreased steam quality, unusual smells when water is poured, or visible crumbling and cracking of the rocks.
Step-by-Step Rock Cleaning
- Allow the sauna and heater to cool completely before touching the rocks. Never handle hot rocks.
- Remove the rocks carefully from the heater basket — they can be heavy, and cracked rocks may break when handled. Wear gloves to protect your hands from rough edges.
- Inspect each rock: Discard any that are cracked, crumbling, or have developed significant surface deposits. Cracked rocks can break explosively when doused with cold water during a session, creating a safety hazard.
- Rinse the rocks with clean water to remove loose debris and surface deposits.
- For stubborn mineral deposits: Soak the rocks in a solution of water and white vinegar (1:5 ratio) for 30–60 minutes to dissolve mineral scale, then scrub with a stiff brush and rinse thoroughly.
- Allow rocks to dry completely before returning them to the heater. Replace the rocks in the heater basket with larger rocks on the bottom and smaller rocks on top.
When to Replace Sauna Rocks
Sauna rocks have a finite lifespan — typically 3–5 years of regular use. Signs they need replacing include significant cracking, crumbling or powdering, dramatic reduction in steam quality, unusual smells, and any rocks that have visibly broken. Our heater accessories range includes replacement sauna rocks suitable for all heater types.
How to Clean a Portable Sauna and Sauna Tent
Portable saunas and sauna tents — including both steam-based and infrared pop-up styles — have different cleaning requirements from built-in cabin saunas due to their fabric or synthetic construction materials.
Cleaning a Portable Steam Sauna Tent
- After each use: Wipe down the interior surfaces — particularly the seat and foot area — with a cloth dampened with diluted vinegar solution to remove sweat residue.
- Open all zips and flaps after use to allow thorough air drying. Never pack away a damp portable sauna — moisture trapped in the folded fabric promotes mould growth rapidly.
- For the steam generator: Empty the water reservoir after every session and wipe it dry. Leaving water in the generator promotes scale build-up and bacterial growth. Periodically run a diluted citric acid solution through the system to descale it.
- Weekly: Spray the interior fabric surfaces with a diluted vinegar solution, wipe down, and allow to dry completely in a ventilated area or outdoors in indirect sunlight.
Cleaning a Portable Infrared Sauna Tent
Portable infrared saunas typically use a collapsible fabric frame with infrared panels. Clean the fabric surfaces with a damp cloth and mild soap solution, working in gentle circular motions. Avoid getting moisture near the infrared panel seams or the control cable connections. Allow to dry completely before folding and storing. Check our sauna tent range for quality portable options with easy-clean materials.
Mould Prevention in Portable Saunas
Mould is the primary risk for portable saunas, and prevention is far easier than treatment. The key practices are: always dry completely before storage, store in a cool dry location (not a damp garage or basement), use a vinegar spray regularly as a preventive measure, and ensure the interior dries after every session before closing up.
How to Clean a Sauna Blanket
Sauna blankets generate significant sweat during every session and require regular cleaning to remain hygienic. The critical rule is that sauna blankets contain embedded electronic heating elements and must never be machine washed or submerged in water.
After Every Session
- Allow the blanket to cool completely before handling.
- Unfold and lay flat in a ventilated area.
- Using a clean cloth dampened with warm water and a small amount of mild soap, wipe the inner surface in overlapping strokes to remove sweat residue.
- Wipe over with a clean damp cloth to remove any soap residue.
- Dry with a clean dry cloth and allow to air dry completely before rolling or storing.
Weekly Deep Clean
Apply a diluted isopropyl alcohol solution (70% IPA diluted 1:1 with water) to a cloth and wipe down both the inner and outer surfaces. This provides effective disinfection without damaging the heating elements or inner coating. Allow to dry completely before storing.
The Liner Solution
The most practical approach to sauna blanket hygiene is using a washable cotton liner inside the blanket for every session. The liner absorbs most of the sweat directly and can be machine-washed after each use. This dramatically reduces the cleaning burden on the blanket itself and significantly extends its lifespan by reducing sweat penetration into the inner lining.
How to Clean a Sauna Suit
Sauna suits — the waterproof or semi-permeable garments worn during exercise or sauna use to increase sweating — accumulate heavy sweat deposits and require thorough cleaning after every use.
After Every Use
- Rinse the suit thoroughly under cool running water immediately after use to flush away sweat before it sets into the material.
- Turn inside out and hand wash with a mild sports detergent in cool water — never hot water, which can damage the waterproof lining.
- Rinse thoroughly until no soap residue remains.
- Hang inside out in a well-ventilated area to dry completely. Never machine dry a sauna suit — heat damages the waterproof lining and seals.
Machine Washing Sauna Suits
Some sauna suits are machine washable — check the manufacturer’s care label. If machine washing is permitted, use a gentle cycle with cold water and a small amount of mild detergent. Place the suit in a mesh laundry bag to prevent zipper and velcro from catching on other items. Always air dry rather than tumble drying.
Odour Management
Sauna suits can develop persistent odours if not cleaned immediately after use or if dried improperly. For odour treatment, soak the suit for 30 minutes in cool water with a cup of white vinegar before washing. Baking soda added to the wash cycle is also effective for odour neutralisation. Always store a completely dry suit in a breathable bag — never sealed in a plastic bag while damp.
Are Gym and Public Saunas Clean?
This is a question many people wonder about but few ask directly — and the honest answer is: it depends entirely on the facility and its cleaning protocols.
The Hygiene Reality of Shared Saunas
Well-managed gym and spa saunas that enforce towel use, conduct regular cleaning sessions, and maintain proper ventilation can be reasonably hygienic. The high temperatures of traditional saunas do reduce bacterial survival on surfaces over time, and frequent use by many people means that high-quality facilities clean their saunas multiple times per day.
However, shared saunas in facilities with poor maintenance culture — infrequent cleaning, no towel requirements, inadequate ventilation — can harbour significant bacterial contamination on bench surfaces, walls, and floors. Foot fungi, Staphylococcus species, and other skin bacteria have all been documented on gym sauna surfaces in studies of public health hygiene.
How to Protect Yourself in Shared Saunas
- Always sit on your own clean towel — never directly on the bench surface.
- Wear flip flops on the floor — athlete’s foot (tinea pedis) is the most common infection acquired in shared sauna and shower environments.
- Don’t touch your face during a session in a shared sauna.
- Shower before and after using a public sauna — the pre-sauna shower reduces the bacterial load you bring into the shared space; the post-sauna shower removes anything acquired during the session.
- Never use a public sauna if you have any contagious skin condition — this includes cold sores, ringworm, or any open skin lesions.
The Case for a Private Home Sauna
The hygiene advantages of a private home sauna are significant. You control the cleaning schedule, you know exactly how the space is maintained, and you’re not sharing benches with strangers. If hygiene concerns about shared facilities are a significant factor in your decision, a home sauna is worth serious consideration. Explore our best home sauna Australia guide and our sauna sale Australia page for currently available options.
Essential Sauna Hygiene Tips
Beyond the cleaning protocols above, certain habits practiced before and during every sauna session dramatically reduce the cleaning burden and maintain a consistently hygienic space.
Before Every Session
- Shower before entering: Entering the sauna clean removes surface bacteria, sunscreen, makeup, and body oils that would otherwise soak into the wood during your session. This single habit reduces the contamination of sauna surfaces by a significant margin.
- Bring a clean towel: A fresh towel per session is the most impactful sauna hygiene practice. Place it on the bench before sitting — it absorbs all sweat before it reaches the wood.
- Tie back hair: Hair products transfer to bench and wall surfaces if hair is loose and damp. Keep hair tied up or use a sauna hat.
After Every Session
- Leave the door ajar: After cleaning and exiting, leave the sauna door slightly open to allow air circulation and complete drying. A closed, damp sauna is a mould-friendly environment.
- Remove wet towels immediately: Don’t leave used, wet towels in the sauna after a session — they introduce significant moisture and bacteria to the space.
- Quick wipe of benches: A 2-minute wipe-down immediately after the session, when surfaces are still warm and sweat hasn’t fully penetrated the wood, is far more effective than cleaning a cooled, dried sauna hours later.
Explore our sauna accessories range for hygienic additions like towel hooks, bench covers, and sauna hats, and read our guide on sauna ventilation to ensure your sauna has adequate airflow for proper drying between sessions.
Best Products for Sauna Cleaning and Care
Using the right products makes sauna maintenance easier, more effective, and safe for your sauna’s materials. Here’s what to keep in your sauna care kit.
Microfibre Cloths
Microfibre cloths are the ideal cleaning tool for sauna wood — they’re soft enough not to damage wood grain, highly absorbent, effective at picking up bacteria and debris even with just water, and reusable. Keep several in your sauna kit and wash regularly to prevent them becoming a bacterial source themselves.
White Vinegar
A large bottle of plain white vinegar diluted with water is one of the most versatile and effective sauna cleaning solutions. Natural, non-toxic, safe for wood and electronics when applied correctly, and effective against bacteria, mineral deposits, and mild mould. Essential in any sauna owner’s cleaning kit.
Fine-Grit Sandpaper
120–180 grit sandpaper is invaluable for refreshing stained, discoloured, or rough bench surfaces. Sanding in the direction of the grain removes the top layer of affected wood, restoring a clean, fresh surface. Keep a small amount in your sauna maintenance kit for use every few months or as needed.
Soft-Bristled Brush
A soft-bristled scrub brush is useful for cleaning sauna rocks, floor slats, and areas where a cloth alone is insufficient — such as corners, crevices, and rough wood surfaces that trap debris.
Purpose-Made Sauna Cleaning Products
For the most convenient and reliably safe cleaning experience, browse our sauna care range for purpose-formulated products designed for sauna wood, rock, and accessory cleaning. These products take the guesswork out of what’s safe to use in your specific sauna type.
For additional guidance on maintaining your sauna’s wood surfaces over the long term, read our guides on sauna wood types and thermowood vs cedar — understanding your wood type helps you care for it most effectively.
Frequently Asked Questions
How do you clean a sauna?
For a traditional wooden sauna: wipe bench surfaces with a damp microfibre cloth after each use; conduct a more thorough clean weekly using diluted white vinegar solution applied with a cloth (never sprayed directly); sweep and clean the floor; and perform a monthly deep clean including sauna rocks and ventilation checks. Always leave the door ajar after cleaning for complete air drying.
How often should you clean a sauna?
A quick bench wipe-down should happen after every session. A thorough surface clean should be done weekly or after every 5–7 uses. A comprehensive deep clean including rocks and floor slats should be performed monthly. Seasonal inspection and exterior treatment is recommended for outdoor saunas.
What should you use to clean sauna wood?
The safest and most effective options are warm water (for routine cleaning), a diluted white vinegar solution (1:10 with water, for deeper cleaning and mild disinfection), diluted hydrogen peroxide (3%, for bacteria and mould), or purpose-made sauna wood cleaners. Never use bleach, ammonia-based products, oil-based cleaners, or harsh chemical sprays — these damage the wood and can produce harmful fumes when the sauna is subsequently heated.
How do you clean an infrared sauna?
Always power off and cool completely before cleaning. Apply cleaning solution to a cloth first — never spray directly onto surfaces. Wipe wood surfaces with a damp cloth in the direction of the grain, carefully avoiding the infrared panel seams. Clean door glass with a cloth dampened with diluted vinegar. Leave the door ajar to air dry after cleaning. Never allow moisture near the infrared panel connections or control systems.
How do you clean sauna rocks?
Remove rocks from the heater when completely cooled. Inspect for cracks and discard any broken or significantly deteriorated rocks. Rinse with clean water. For mineral deposits, soak in a 1:5 vinegar-water solution for 30–60 minutes, scrub with a stiff brush, and rinse thoroughly. Allow to dry completely before returning to the heater. Replace rocks every 3–5 years or when cracking or quality deterioration becomes apparent.
How do you clean a portable sauna tent?
Wipe interior surfaces after each use with a cloth dampened with diluted vinegar solution. Open all zips and air dry completely before storage — never pack away damp. For steam generators, empty the reservoir after every use and descale periodically with diluted citric acid. Weekly, spray interior fabric surfaces with vinegar solution, wipe down, and air dry thoroughly outdoors.
Does a sauna clean your pores?
Yes — the heat causes pore dilation and a flushing sweat that carries debris outward from within the pore. However, this cleansing benefit is only realised if you shower immediately after the session to wash away the sweat and flushed material before pores close again. If you let post-sauna sweat dry on your skin, the debris can be reabsorbed into pores as they close.
Are gym saunas clean?
Quality varies significantly by facility. Well-managed gyms with strong cleaning protocols and mandatory towel policies can be reasonably hygienic. Poorly maintained shared saunas can harbour significant bacterial contamination. Always sit on your own towel, wear flip-flops on the floor, shower before and after, and avoid public saunas if you have any contagious skin condition. A private home sauna eliminates these hygiene concerns entirely.
How do you clean a sauna suit?
Rinse immediately after use under cool water. Hand wash with mild sports detergent in cool water — not hot, which damages the waterproof lining. Rinse thoroughly and hang inside out to air dry. Never tumble dry. For persistent odours, soak in cool water with white vinegar before washing. Store completely dry in a breathable bag.
