Home Sauna Maintenance Guide
Proper maintenance extends your sauna's lifespan, ensures safe operation, and keeps it looking beautiful for years to come.
After Each Use
Infrared Saunas
- Wipe down benches and backrests with a damp cloth to remove sweat
- Leave the door open for 15–30 minutes to allow moisture to evaporate
- Check for any water pooling on the floor and wipe dry
- Turn off the sauna and unplug if not in daily use
Traditional Saunas
- Remove any water from the floor and benches
- Leave the door and vent open to dry the interior completely
- Empty the water bucket if used
- For wood-burning models: allow ashes to cool completely before disposal
Sauna Blankets
- Wipe the interior with a damp cloth after each use
- Allow to air dry completely before folding
- Store flat or loosely rolled (never fold sharply while warm)
- Check zipper and seams for wear
Weekly Maintenance
- Inspect wood surfaces for signs of moisture damage or mold
- Clean the floor with a mild, sauna-safe cleaner (avoid harsh chemicals)
- Check heater elements (infrared) or rocks (traditional) for debris
- Verify ventilation is unobstructed
- Test the control panel and timer functions
Monthly Maintenance
Wood Care
- Lightly sand any rough spots with fine-grit sandpaper (220-grit)
- Apply sauna-safe wood conditioner or oil if the wood looks dry
- Check for cracks or splits in the wood, especially around heater areas
- For outdoor saunas: inspect exterior finish and re-seal if needed
Electrical Check
- Inspect power cord for damage or wear
- Ensure outlet is not warm to the touch during use
- Check that GFCI protection is functioning (if applicable)
- Verify all heater connections are secure (infrared models)
Annual Maintenance
Infrared Saunas
- Deep clean all wood surfaces with sauna-specific cleaner
- Inspect and clean infrared heater panels
- Check all electrical connections
- Re-apply wood finish if needed
- Verify door seals and hinges
Traditional Saunas
- Replace heater rocks (they degrade over time)
- Clean chimney and flue (wood-burning models)
- Inspect and service the heater element
- Deep clean and re-condition all wood surfaces
- Check exterior foundation and drainage
- Inspect roof and walls for water intrusion (outdoor models)
⚠️ Common Maintenance Mistakes
- Using harsh chemicals: Bleach, ammonia, and strong cleaners can damage wood and leave toxic residues. Use only sauna-safe cleaners.
- Skipping ventilation: Trapped moisture leads to mold and wood rot. Always dry your sauna after use.
- Ignoring electrical issues: Warm outlets, flickering lights, or tripped breakers need immediate professional attention.
- Over-oiling wood: Too much conditioner can make surfaces slippery and attract dirt. Apply sparingly.
- Neglecting the exterior: Outdoor saunas need regular sealing to prevent weather damage.
Ventilation Best Practices
Proper ventilation is critical for both performance and longevity:
- Install intake and exhaust vents per manufacturer specifications
- Keep vents unobstructed by furniture or storage
- Run a small fan after sessions to speed drying (optional)
- In humid climates, consider a dehumidifier in the sauna room
When to Call a Professional
Contact a qualified technician if you notice:
- Electrical issues (tripped breakers, warm outlets, burning smells)
- Heater malfunction (not heating, uneven heat, error codes)
- Structural damage (cracked wood, loose bands, water intrusion)
- Mold that doesn't respond to cleaning
- Any issue covered under warranty (don't DIY warranty repairs)
