The Infrared Sauna Maintenance Protocol: Emitters, Wood, and Wiring
An infrared sauna is a low-maintenance appliance with a wooden interior — and the wood is where most care goes. The emitters want to be clean and unobstructed; the cedar wants to stay dry, bare, and out of contact with chemicals; the wiring wants an occasional look. None of it takes long.
After every session
Leave the door open for fifteen to thirty minutes with the heaters off so the cabin dries. Wipe the bench where you sat with a clean, dry or barely damp cloth. Use a towel on the bench and under your feet during sessions; it is the single habit that keeps the wood looking new. Never leave wet towels or clothing in the cabin.
Weekly
- Bench and floorWipe with a soft cloth dampened in plain water, or water with a very small amount of mild soap if the manufacturer permits. Dry immediately. No bleach, no solvents, no abrasive cleaners, no oil or varnish on interior wood — sealed wood cannot breathe and can off-gas when heated.
- Emitter surfacesWith the sauna cool and unplugged, wipe carbon or ceramic emitter panels gently with a dry microfiber cloth. Dust on an emitter is a thin insulating layer; it reduces output and raises surface temperature. Never spray liquid on or near emitters.
- GlassClean the door glass with a dilute vinegar-and-water solution on a cloth. Avoid ammonia products near wood and seals.
Monthly
- ConnectionsUnplugged, inspect the visible power cord, the plug, and the connection points between panels for heat discoloration, loose fit, or damage. A warm plug or a scorched outlet face is a stop-use-and-call finding.
- Control panelConfirm the displayed temperature roughly matches a thermometer hung at bench height after a normal warm-up, and that every emitter zone the panel reports as on is actually warm to the hand at a safe distance.
- HardwareCheck bench supports, door hinges, magnetic catches, and any panel clips or buckles for looseness. Tighten by hand.
- WoodLook for staining, raised grain, or dark spots that indicate moisture is not drying between sessions. Improve post-session ventilation if you see them.
Occasionally
Light surface marks and sweat stains on unfinished cedar or hemlock can be lifted with a fine-grit sandpaper (around 220) used lightly along the grain, then wiped clean. This is normal care for an unfinished softwood and restores the surface without chemicals. Do not sand emitter frames, and do not sand near glass or seals.
If the cabin is in a humid space — a basement, a garage — a small dehumidifier in the room, not in the cabin, protects the wood between sessions.
What not to do
| Avoid | Because |
|---|---|
| Oiling, staining, or sealing interior wood | Sealed wood cannot release moisture and finishes can off-gas when heated. Interior wood stays bare. |
| Bleach, solvents, or spray cleaners | They damage wood fibers and can be absorbed and released as vapour during sessions. |
| Liquids near emitters or the control unit | Electrical components; water and cleaners belong nowhere near them. |
| Blocking emitters with towels, cushions, or backrests | Blocked emitters run hot and lose output. Keep the surfaces clear. |
| Extension cords or shared circuits | Voltage drop and nuisance trips; a dedicated outlet is the standard. |
Electrical repairs, emitter replacement, and control-board faults are for the manufacturer or a qualified technician; see our Warranty Policy for coverage by product.
Want the care sheet for the specific wood and emitter type you are considering?
Cedar, hemlock, and basswood interiors behave differently, and carbon and ceramic emitters clean differently. Our concierge will send the manufacturer's care instructions for the model before you buy.

Common questions
- How do you clean an infrared sauna?
- Wipe benches and floor with a soft cloth dampened in plain water and dry immediately. Dust emitters with a dry microfiber cloth while unplugged. Clean glass with dilute vinegar and water. No bleach, solvents, oils, or sprays.
- Should I oil or seal the wood inside an infrared sauna?
- No. Interior wood stays bare so it can release moisture; oils and sealers can off-gas when heated. Exterior wood on outdoor units may be treated per the manufacturer.
- How do I clean infrared heater panels?
- With the sauna cool and unplugged, wipe the emitter surface gently with a dry microfiber cloth. Never spray liquid on or near emitters.
- How do I remove sweat stains from sauna wood?
- Light sanding along the grain with fine (about 220-grit) sandpaper, then wipe clean. Use a towel on the bench during sessions to prevent them.
- Why does my infrared sauna smell?
- Usually moisture that is not drying between sessions, or wet towels left inside. Leave the door open after each session and improve room ventilation or add a dehumidifier to the room.
- How often should I inspect the wiring?
- Monthly, unplugged: cord, plug, and panel connections for heat discoloration or looseness. A warm plug or scorched outlet is a stop-use-and-call finding.
- Can I use my infrared sauna every day?
- The cabin is built for it. Maintenance stays the same; let it dry between sessions and keep emitters clear.
