Maintaining an infrared sauna is significantly easier than a traditional steam sauna because there is no high humidity or standing water to manage. However, because you are still sweating and shedding skin cells, a consistent cleaning rhythm is vital to prevent bacterial growth and wood staining. Following a structured sauna maintenance routine ensures your investment remains a clean, inviting space for your wellness practice.
After Each Use: The Immediate Reset
The most important part of sauna hygiene happens immediately after you step out. Taking five minutes to reset the space prevents long-term damage to the wood and keeps odors at bay.
Wipe Down Surfaces
Use a clean, damp cloth to wipe away any visible sweat from the bench, backrests, and floor. Infrared saunas are typically made of softwoods like cedar or hemlock, which are porous and can absorb oils if sweat is left to sit.
Ventilation and Airing Out
Leave the sauna door open for at least 15 to 20 minutes after your session. This allows any residual moisture to evaporate and ensures fresh air circulation, which is a key component of sauna safety and hygiene.
Weekly Cleaning: The Surface Refresh
Even if you use towels during every session, a weekly refresh is necessary to remove accumulated dust and skin oils that a simple wipe-down might miss.
Vacuuming the Floor
Dust and hair can accumulate quickly in the small corners of a sauna cabin. Use a vacuum attachment to clean the floor and the gaps between the bench slats. This prevents debris from being ground into the wood grain.
Mild Cleaning Solution
Wipe the benches and walls with a solution of warm water and a few drops of mild, non-toxic dish soap or a specialized sauna cleaner. Avoid harsh chemicals or bleach, as the wood will absorb these substances and release potentially harmful fumes when the sauna heats up during your next sauna routine.
Monthly Maintenance: Deep Care
Once a month, perform a more thorough inspection to ensure the structural integrity and cleanliness of the unit.
Glass and Hardware
Clean the glass door and windows using a vinegar-and-water solution to remove fingerprints and smudges. Check the door hinges and handle to ensure they are tight and functioning correctly.
Light Sanding
If you notice stubborn sweat stains or rough patches on the bench, use a fine-grit sandpaper to lightly sand the area. This restores the wood's natural appearance and removes deeply embedded oils. Always vacuum thoroughly after sanding.
Best Practices for Reducing Cleaning Frequency
The best way to keep your sauna clean is to prevent it from getting dirty in the first place. Always sit on at least two towels—one for the bench and one for under your feet—to catch as much perspiration as possible.

Frequently Asked Questions
Can I use a pressure washer on my infrared sauna?
No. Never use a pressure washer or a garden hose inside an infrared sauna. The excessive water can damage the infrared heaters, electrical components, and cause the wood to warp or crack.
How do I remove odors from the wood?
If the wood begins to smell, a solution of baking soda and water can help neutralize odors. For persistent smells, a light sanding of the interior wood surfaces usually resolves the issue by exposing fresh, aromatic wood grain.
Do I need to clean the infrared heaters?
Infrared heaters generally do not require cleaning. If they become dusty, you can gently wipe the protective grilles with a dry cloth when the unit is completely cool and unplugged.
