Saunas are a place of relaxation, a little oasis of heat to escape the stresses of daily life. However, when you have your own sauna, you have to do a little bit of work to keep it in great condition. How do you get sweat stains out of your sauna?
The best way to remove sweat stains from your sauna is to apply a natural cleaner to the wood. These cleaners can easily be made at home with things like vinegar, baking soda, or essential oils. Take your solution, with a rag, and gently wash the surfaces in your sauna. Then, wipe them down with water.
As simple as this all sounds, there are some other methods you can use to clean sweat stains, as well as things you can do to prevent them in the first place. Keep reading, and I’ll go over all of these things!
Best Methods to Remove Sweat Stains
Thankfully, there are several natural cleaning solutions that can effectively tackle sweat stains. Here’s how you can make your sauna look new again, naturally.
Vinegar Solution: Distilled white vinegar is a powerful natural cleaner. Mix one part vinegar with two parts warm water. Dip a soft cloth into the mixture and wring it out, so it’s damp, not soaking.

Gently scrub the stained area in the direction of the wood grain. Once you’ve cleaned the area, rinse your cloth with warm water, wring it out, and wipe down the area again to remove any leftover vinegar.
Baking Soda Paste: For more stubborn stains, you can use baking soda. Mix one part baking soda with two parts water to form a paste.
Apply this paste to the stain and gently scrub with a cloth. After scrubbing, wipe away the paste with a damp cloth and dry the area thoroughly.
Essential Oil Solution: Certain essential oils, like tea tree and eucalyptus, have natural antifungal and antibacterial properties.
Add a few drops of your chosen essential oil to warm water. Use this solution to clean the sweat stains using a soft cloth. Not only does this method clean, but it also leaves a pleasant, refreshing scent in your sauna.
Essential oils are just one way that you can make your sauna smell amazing. If you want to see all of the other ways, I wrote another article all about that!
Always remember to test any solution on a small, less visible area of the sauna before applying it fully. If there’s no adverse reaction, you can proceed to clean the rest.
Use Natural Methods Over Harsh Chemical Cleaners
A typical first instinct might be to reach for a bottle of heavy-duty chemical cleaner to wipe those stains away. However, using harsh chemicals to clean your sauna can have some serious drawbacks.
First, such products can harm the very material we aim to clean. The hot, humid environment inside a sauna can amplify the effects of chemical cleaners, potentially damaging the wood and decreasing the lifespan of your sauna.

Secondly, chemical residues left behind could be harmful to humans. Many of these cleaners emit volatile organic compounds (VOCs) that can cause respiratory problems, headaches, and other health issues when inhaled – especially in a hot and steamy environment.
In fact there are many things in your sauna that can cause headaches. In another article, I wrote about all of the potential causes of headaches when you’re using a sauna, as well as how to prevent it from happening.
Lastly, using chemical cleaners isn’t particularly eco-friendly. They often contain substances that can harm our ecosystems when washed away into our water systems.
In light of these considerations, opting for natural methods can protect both your sauna and the health of its users, while also being kind to the environment.
How to Prevent Sauna Sweat Stains
Prevention is always better than cure, and sweat stains in saunas are no exception. Here are some strategies to prevent sweat stains from forming in the first place:
Regular Cleaning: By routinely cleaning your sauna with the aforementioned natural methods, you’ll prevent sweat and impurities from building up and staining the wood.
Using Towels: Encourage users to sit or lie on towels while in the sauna. The towels will absorb most of the sweat and impurities, preventing them from reaching the wooden surfaces.
Ventilation: Proper ventilation is crucial to prevent the buildup of moisture and impurities. If your sauna has ventilation or exhaust features, make sure they’re used appropriately. If it doesn’t, consider leaving the door ajar after use to allow moisture to escape.
Health Risks From Sweat Stains and Poor Cleaning Habits
While sweat stains themselves do not pose a direct health risk, they can become breeding grounds for bacteria and fungi if not cleaned regularly. These organisms may cause unpleasant odors and could potentially lead to health problems like respiratory issues or skin infections.

One of the biggest causes of a stinky sauna is improper cleaning. If you want to make sure that your sauna never stinks, check out another article I wrote!
On top of this, as mentioned earlier, using harsh chemical cleaners can introduce harmful VOCs into the sauna environment.
The heat and steam inside the sauna can amplify the potential health risks of these substances, leading to problems like respiratory irritation, dizziness, nausea, and even long-term health complications with prolonged exposure.
The Bottom Line
A well-maintained sauna provides an environment for relaxation, rejuvenation, and holistic wellness. However, to keep it as an oasis of health and comfort, we need to be vigilant in our cleaning habits.
By preferring natural cleaning methods over harsh chemical cleaners, we can effectively remove sweat stains while preserving the integrity of the sauna and the well-being of its users.
Regular cleaning, using towels, and ensuring proper ventilation are simple preventive measures that go a long way in maintaining a clean and pleasant sauna experience. The path to detoxification need not be a road littered with harmful residues.
It’s our responsibility to make sure that the space we retreat into for cleansing our bodies is as clean and safe as it can be. Let’s step into our saunas with the peace of mind that only comes from knowing we’ve done our best in their care and upkeep.
