How do I clean the sauna?


Basics of Cleaning a Sauna: Soaping and Mopping


If you use your sauna frequently enough, you might wish to give the floor a deeper clean. A mild detergent and warm water can clean stains left behind by dirt tracked into your sauna. Use a light, chemical-free, liquid deodorizing cleaner to mop the floors of your sauna to keep it looking and smelling fresh. 


  • Avoid harsh cleaning agents: Do not use chemical cleaning agents on wood. They might bleach the wood, ruining the surface permanently.

  • Use proper sanitization methods: Since sauna wood is extremely dry and sensitive to moisture, do not sanitize with a high-pressure washer or a water hose.

  • Use soft water: You might never need to use anything else to cleanse the wood elements of your sauna if you clean it every time while using pure water rather than hard water.

  • Keep airing it out: After you've cleaned your sauna, let it air out. Leave the sauna door open as you leave so that it may ventilate and stay fresh. The interior will ultimately dry out completely.

Cleaning a Sauna with Eco-Friendly Supplies


Traditional cleaning supplies are hard on your sauna benches, and can be harmful to humans and the environment. There are many easy and safe techniques to clean your sauna, with ingredients readily available in every home. What's more, if you are environmentally conscious, these materials you use to clean your sauna are ecologically harmonious.


Baking soda


Sauna surfaces respond well to baking soda, which also eliminates foul smells. For instance, it eliminates offensive refrigerator odors. To thoroughly clean the surfaces of the sauna, combine 5 liters of water with a pinch of baking soda.


Organic cider vinegar


Organic cider vinegar is a good cleanser that costs a fraction of what commercial products do. Use a mixture of three parts warm water and one part apple cider vinegar. This blend of cider vinegar and water works well to sanitize and disinfect. Apply on every part of the sauna. You won't have to worry about any lingering pollutants when you remove all stains and grime.


Linseed oil soap with potassium


The best mild soap for cleaning the sauna is linseed oil potassium soap. The cold-pressed linseed oil used to make the potassium soap makes it ideal for sanitizing surfaces, including wood floors.

Shake the bottle thoroughly before using it to scrub the benches of the sauna. Combine five liters of tepid or cold water with one liter of soap (1:5). Scrub the seats along the wood grain.


Deep-Cleaning a Sauna: Sandpaper for Heavy Dirt Removal


You have another choice if soap cannot restore the appearance. No more than once a year, gently sand the seats to get the wood’s surface back to its former appearance. Use fine-grained sandpaper to remove highly stubborn dirt or discoloration from any wood sauna type. You can also use a sanding disc. To prevent fine particles from landing on the rocks while sanding, cover the sauna heater with plastic and clean all the surfaces with a vacuum upon sanding. Then use a moist cloth to mop the seats and backrests of the sauna.


Please be aware, though, that thermally modified wood does not allow for this. Also, do not paint the sauna's interior paneling or internal furnishings, such as loungers. Likewise, using a wood sealer or wood preservative inside a sauna is not recommended.
