The article “How to maintain and care for your sauna” tells how to care for your sauna properly. Which detergents should be used to wash the sauna? What should be taken into account after a sauna session? How do you extend the life of your sauna?
Unfortunately, without maintenance, a sauna is not a long-lasting investment and is therefore not ecological. So, if you put a lot of money into building a sauna, you must also remember to take care of it. By maintaining the sauna, you increase its longevity significantly.
If you have bought your sauna, the manufacturer will provide care instructions specifically for your sauna. In this article, however, I have collected the best tips that work for almost every sauna.

How to wash the sauna
A good rule of thumb is to wash the sauna 2-3 times a year when you sauna once a week. If you take saunas more often, you should clean the sauna more often.
Which detergents should be used to wash the sauna?
I am a supporter of natural and environmentally friendly detergents. I have tried several different ecological products that can be found in most households’ kitchen cupboards. I have had excellent experiences with some of these; they have always made my sauna clean and fresh. I haven’t, however, tried all of them, like a linseed oil sponge, black soap or steam cleaner.
I recommend these ingredients for washing the sauna:
- Vinegar
- Citric acid
- Baking soda
- Clay soap
- Euca washing concentrate
- Soda crystal
- Linseed oil soap
- Marius Fabre black soap
- Steam cleaner

How do you wash your sauna:
- Move removable benches and stools out of the way and put them in the washroom.
- Vacuum or brush the dust off the sauna floors, walls and ceiling.
- Wet the wooden surfaces of the benches first with warm water to open the surface of the wood.
- Make the detergent mixture in a bucket, or if you use universal stone, follow their instructions.
- Brush the benches with a soft brush, sponge or sauna brush in the direction of the wood grain.
- Finally, rinse the benches with cold water to seal the surface of the wood. You can rinse with warm water first.
- Dry the benches with a dryer.
- Wash and rinse the walls from the bottom up. Washing the walls every time is not necessary, so monitor the situation.
- Also, wash buckets, ladles, brushes and other sauna utensils.
- Wash the floor drain and grate. Empty the hair and other debris from the floor drain.
- Finally, wash the floor and let it dry.
- Turn on the sauna for half an hour so that the sauna dries properly. Bring the freshly washed removable benches and the stool back to the sauna to dry.
- You can also occasionally rinse or brush the sauna benches between washes.
Note that the benches must dry adequately every time you heat the sauna.

How to oil sauna the benches
This is also a good time to oil the sauna benches. Oiling the sauna benches should be done once or twice a year.
The best substance for oiling sauna boards is pure paraffin oil.
This is how you oil the sauna benches:
- Wash the sauna, preferably the day before, and dry it properly.
- Heat the sauna to 40 degrees, and place the oil can onto the benches to get warm. The heat opens the wood grain, and the oil is absorbed better.
- Apply the oil with a brush or sponge on both sides of the benches.
- It’s best to start with the end surfaces, where the oil is absorbed quickly.
- Treat all visible surfaces with oil, including the backrests.
- Remember to oil the benches from the bottom as well.
- Allow the oil to absorb for 1-2 hours.
- Wipe off any excess oil with a lint-free cloth.
- Note that the oil must be adequately absorbed before you heat the sauna. Preferably, wait until the next day.

Tips for caring for the sauna:
- The best oil to use for your benches is paraffin oil.
- Remember to change and wash the sauna stones once a year.
- Check the condition of the sauna heater stones and replace them with new ones if necessary.
- Especially in an electric stove, the stove stones must be changed or re-laid on top of each other. Old stones weigh down the electrical resistances; thus, more electricity is consumed, and the sauna experience is no longer as good.

This is how you change the stove stones:
- Empty the stones and vacuum the inside of the stove.
- Wipe inside and outside with a damp cloth.
- Put the stones back according to the stove manufacturer’s instructions.

Care for your sauna at the end of every sauna session
- The last tip is always to remember to maintain the sauna at the end of the sauna session.
- Dry the shelves and the floor, and leave the electric heater on for another 20 minutes so the sauna dries properly.
- Keep the door closed to prevent moisture entering the bathroom or dressing room.
The above instructions are essential to keep the sauna in good condition for as long as possible. You want to enjoy a clean and fresh sauna!
What do you think? Will you start following these instructions now, or do you already care for your sauna regularly?
