Cleaning and Maintaining Sauna Benches
Sauna benches take the most sweat, so they need the most care. Here is how to clean, sand and maintain benches to keep them fresh, cool and hygienic.
The short answer
Sauna benches take the most sweat, so care for them most: wipe after use, clean weekly with warm water, lift them out to dry both faces, and sand periodically to refresh the bare wood. A towel under you is the best preventive of all.
Benches are where your skin meets the sauna, so they collect the most sweat and need the most attention. Keep them fresh and they stay cool, clean and comfortable.
The daily habit
Regular cleaning
Weekly, or after heavy use:
- Wipe benches and backrests with warm water and a little mild sauna cleaner.
- Rinse so no cleaner residue is left on the bare wood.
- Lift the benches out if they are removable, and clean and dry underneath — a common hidden source of smell.
- Dry both faces fully with the vents open before refitting.
Periodic refresh
Keep them removable
Benches designed to lift out are far easier to keep hygienic — you can clean and dry both faces and the floor beneath. If yours are fixed, at least clean thoroughly underneath and ensure the space dries.
What not to use
Never seal benches with varnish or use harsh chemicals — the bare wood absorbs and heats them. Warm water, mild sauna cleaner, light sanding and optional sauna oil are all you need. Fold bench care into your overall cleaning routine, and the benches stay cool, smooth and sweet for years.
Little habits, easy benches
Benches stay fresh with small, regular habits far more than with occasional deep scrubs. The single most effective one is sitting on a towel, which keeps sweat out of the bare wood and prevents most staining, odour and cleaning before it starts. Wiping the benches down after each session and letting them dry with the vents open handles most of the rest.
For the weekly clean, warm water and a little mild sauna cleaner, a rinse, and thorough drying keep benches hygienic; lifting removable benches out to clean and dry underneath tackles a common hidden source of smell. Every so often, light sanding refreshes the surface, since sauna wood is unsealed and stains lift out with the top layer.
Keep it simple and safe. Never seal benches with varnish or use harsh chemicals — the bare wood absorbs and heats them. Warm water, mild sauna cleaner, light sanding and an optional food-safe sauna oil are all you need to keep the benches cool, smooth and sweet-smelling for years.
Frequently asked questions
How do you clean sauna benches?
Wipe them after each use, and weekly clean with warm water and a mild sauna cleaner, rinse, lift them out to clean and dry underneath, then dry both faces fully with the vents open.
How do you keep sauna benches hygienic?
Sit on a towel to keep sweat out of the wood, wipe benches after use, clean regularly, and dry them thoroughly. A towel plus drying prevents most hygiene problems.
How often should you sand sauna benches?
Whenever they look stained or grey, or as part of yearly maintenance. Light sanding removes the top layer of sweat-soaked wood and restores a fresh surface.
Should sauna benches be removable?
Ideally yes. Removable benches are far easier to keep hygienic because you can clean and dry both faces and the floor beneath, which is a common hidden source of smell.
What should you not use on sauna benches?
No varnish, polyurethane or film finishes, and no harsh chemicals — the bare wood absorbs and heats them. Use warm water, mild sauna cleaner, light sanding and optional food-safe sauna oil.
What is the easiest way to keep sauna benches fresh?
Sit on a towel to keep sweat out of the wood, wipe the benches after each session, and let them dry with the vents open. These small habits prevent most staining and odour before it starts.
How do you clean sauna benches weekly?
Wipe with warm water and a little mild sauna cleaner, rinse, lift removable benches out to clean and dry underneath, then dry both faces fully with the vents open.
How often should you sand sauna benches?
Whenever they look stained or grey, or as part of yearly maintenance. Because sauna wood is unsealed, light sanding lifts the top layer of sweat-soaked wood and restores a fresh surface.
Should you seal sauna benches?
No — leave them bare, with an optional food-safe sauna oil the only treatment. Varnish and film finishes get hot, off-gas and blister at sauna temperatures, and harsh chemicals are absorbed by the bare wood.
