Cleaning the wood

Water and a soft cloth — that's it. What never to use, plus what to do if a stain sets in.

The wood inside your sauna is a living surface. It absorbs and releases moisture as the cabin heats and cools, and over time it develops a patina from regular use.

What to use

  • Water and a soft cloth for normal cleaning
  • A soft brush for the bench surface if it gets gritty (rare; only if foreign material is brought in)

What not to use

  • Soap or detergent (these can be absorbed by the wood and released as off-gassing during heating)
  • Bleach or any harsh cleaner
  • Wood polish, varnish, or any sealing product (the wood needs to breathe and absorb moisture)
  • Pressure washers (excessive water saturates the wood)

For stubborn stains, contact our team before applying anything stronger than water. We can advise based on the specific situation.
