I have been asked recently “What is the best way to keep my sauna clean, and to remove stains left by body oils and perspiration” ?
The best way is to start early, to establish a routine for cleaning the sauna from new, on a daily and weekly basis.
The wood that all saunas are manufactured from is a natural product and will absorb perspiration and body oils/fats, so it is important not to allow this to become a problem by regularly cleaning the areas which bodies come into contact with, this will usually be the bench seats and backrests/wall panels.
It is worth noting also, that the best way to keep the sauna benches clean is to encourage users to take a towel into the sauna to sit on, this will also prevent Chlorinated water from damaging bench seats if your sauna is on poolside.
At the end of each day, turn the sauna off and sweep and mop the floor.
Wash the bench seats with a soapy water solution, NEVER use disinfectant as this may cause respiratory problems when the sauna heats up.
If you see any significant stains on the walls or backrests, these can of course be attended to during this daily process.
Once you have carried out the above, leave the sauna door open to allow the timber to dry out, and also to allow air in to keep the sauna smelling fresher.
On a weekly basis, wash/scrub the walls in the areas where users lean to remove stains.
It is important not to use too much water as this may cause the sauna timber to rot, and NEVER use a pressure washer.
When cleaning the sauna, this is also a good time to check for any items that may have been left by users and which may become a hazard such as towels, swimwear and newspapers, so do check under the sauna benches and behind the screen wall if the sauna if fitted with a concealed heater.
Don’t forget to give the door a clean, as finger marks around the door handle need to be removed.
The use of a specialist sauna essence will also keep the sauna smelling fresher.
Never treat the interior of the sauna with varnish, as this may cause breathing problems as with the disinfectant.
If your sauna is badly stained in certain areas, it may be possible to remove these stains with a light sandpapering, but the best practice is not to allow these stains to build up in the first place.
