Cleaning the Wood Inside an Infrared Sauna

I keep a stack of clean towels next to my sauna and put one down on the bench before I sit. It catches most of the sweat and body oil, which means the wood stays drier and I spend less time wiping later. After a session, I take that towel out, let it dry, and put it in the laundry. I do not leave damp towels folded on the bench overnight.

When I clean the wood, I go gently. I use a soft cloth that is barely damp, not wet, and I wipe with the grain. I do not scrub hard or flood the seams. If I have a spot near the backrest or armrest, I start with plain water and a little patience. If the maker’s guidance allows a mild soap, I use only a small amount and follow it with a clean damp cloth. I avoid bleach, ammonia, essential oils, furniture polish, and rough scouring pads. Those can dull the wood or leave a residue that heats up later.

Airing it out matters as much as wiping. After I finish, I leave the door open for a while and let the sauna cool completely before I close it up. I also wipe down the bench and any handholds I touched. If the room is humid, I run a fan nearby, but I do not point it into the heater.

The maker’s care guidance is the first place I check. Wood types and finishes differ, so I keep the manual with the sauna and follow its limits on moisture and cleaners. When I want a plain reference for bench layout and general care reminders, I keep the 2 Person Infrared Sauna page bookmarked. I also check the provider’s own current terms and instructions before trying anything new.

My routine is simple:

• Put a fresh towel on the bench before sitting.
• Wipe the wood lightly with a barely damp cloth after it cools.
• Avoid harsh cleaners and excess water.
• Leave the door open to air it out.
• Check the maker’s care instructions before changing products.

That keeps the wood looking cared for without turning cleaning into a project.
