Cleaning your IceSauna with our guide
A well-maintained sauna isn’t just about aesthetics—it ensures hygiene, longevity, and the perfect sauna experience. The IceSauna is engineered for easy cleaning, so staying on top of maintenance takes just a few minutes.
Every use
Use towels
Always sit or lie on a towel to prevent sweat and oil buildup on the benches.
Ventilate properly
Keep the sauna fresh by opening the vent holes in winter and leaving the door slightly open in summer.
Wipe down surfaces
A quick wipe with a damp cloth is all it takes to keep benches, walls, and backrests clean.
Weekly & deep cleaning
Sweep or vacuum
Remove dust and dirt from the floor. Our Icetubs Drip Tray minimizes debris buildup.
Mild cleaning solutions only
Use sauna specific cleaners to protect the thermowood and stainless steel. Avoid harsh chemicals and chlorine.
Deep clean every 6 months
Scrub benches, walls, and floors with a sauna detergent. Wipe the heater with a damp cloth and remove any limescale buildup with a 10% citric acid solution.

Cleaning your heater
The Harvia Cilindro electric heater is at the heart of your sauna experience. A little care keeps it running at peak performance.
Stone maintenance
Inspect regularly
Sauna stones degrade over time. Check for cracks every few months and replace damaged stones.
Stack properly
Loose stacking improves airflow and prevents overheating. Restack at least once a year and remove stone debris from the heater base.
Cleaning & first time use
Wipe the heater exterior
Keep the stainless steel polished with a damp cloth. Avoid abrasive cleaners or chlorine.
First time use
The first time you use your sauna, the heater and stones may emit a slight odor. This is normal, just ventilate the space well by opening vents and door to allow the smell to escape.

Protecting your sauna in every season
The IceSauna is built to withstand all climates, but a little seasonal care ensures it stays in perfect condition no matter the weather.
Winterization
Preheat before use
The heater’s overheat protector may trip in freezing conditions (below -5°C). Allow the heater to warm to 18°C before resetting it.
Occasionally run the heater
If left unused for long periods, turn the heater on periodically to prevent excess moisture buildup.
Summer & humid climates
Protect from direct sunlight
If possible, place your sauna in a shaded area to preserve the wood and prevent drying.
Ensure proper ventilation
High humidity can trap excess moisture. Keep air vents and door slightly open after use.

Maximizing the lifespan of your IceSauna
The IceSauna is built for durability, but simple care keeps it looking and performing like new for decades.
Thermowood cleaning
Oil once a year
Apply high-quality wood oil annually to protect against moisture and enhance durability.
Light sanding for stains
If discoloration occurs, gently sand the affected area and reapply oil.
Stainless steel maintenance
Clean regularly
Use a microfiber cloth with mild detergent to keep stainless steel parts pristine.
Avoid harsh chemicals
Do not use chlorine or abrasive cleaners, as they can cause corrosion over time.
Water and aromas
Control humidity
Dry sauna air needs balancing. Pour clean household water on the stones to reach the right humidity levels.
Use only sauna safe aromas
Never add essential oils directly to the heater or stones. Add the essential oils as instructed into the water. Only use sauna approved aroma infusions.

Frequently asked questions about cleaning a sauna
How often should I clean my IceSauna?
For daily maintenance, wipe down surfaces and ensure proper ventilation. A deeper clean, including sweeping or vacuuming, should be done weekly. Every six months, we recommend a full deep clean with sauna detergent to maintain optimal hygiene.
Do I need to replace the sauna stones, if so how often?
Yes. Over time, sauna stones degrade due to repeated heating and cooling. Inspect them every few months and replace any cracked or crumbling stones. We recommend completely rearranging and refreshing the stones at least once a year for even heat distribution and to prevent heater overheating.
What should I do if my sauna heater doesn’t turn on in freezing weather?
If the temperature has dropped below -5°C, the overheat protector may have been triggered. Bring the heater to a warmer environment (above 18°C) and reset it. To avoid this issue, ensure proper insulation and occasionally run the heater if the sauna is unused for extended periods.
Can I use any cleaning products on my IceSauna?
No. Avoid harsh chemicals, chlorine-based cleaners, and abrasive materials, as they can damage the thermowood and stainless steel. Instead, use sauna-specific cleaning solutions or a simple mix of warm water and mild detergent.
How can I prevent my sauna from smelling musty?
Proper ventilation is key. After every session, leave the sauna door slightly open and vents fully open to allow fresh air to circulate. Also, ensure all surfaces are dry before closing the sauna. A deep clean every six months further helps to keep your IceSauna fresh.
Can I use essential oils in my sauna?
Only sauna-safe aroma infusions should be used. Essential oils should never be poured directly onto the stones or heater, as they can create a fire hazard and damage components. Instead, combine a sauna-safe aroma blend in water and pour small amounts onto the stones.
Does stainless steel require special care?
Yes. Use a microfiber cloth and mild detergent to clean stainless steel components. Avoid chlorine, acidic cleaners, or abrasive sponges, as they can cause corrosion or discoloration over time. Regularly wiping down stainless steel ensures it stays sleek and rust-free.
How can I prevent overheating or underheating issues with my Harvia Cilindro heater?
Ensure that the stones are correctly stacked to allow proper airflow, and regularly inspect the heating elements for any signs of damage. If you experience consistent heating issues, please contact us.
