Keeping sauna wood clean is vital for maintaining its beauty, longevity, and hygiene. Follow these expert tips to care for your sauna properly.

1. Best Way to Clean Sauna Wood
Use a mixture of warm water and mild soap. Gently scrub with a soft brush or sponge to remove dirt and sweat. Avoid soaking the wood.
2. How Often Should You Clean Sauna Wood?
Wipe down surfaces after every use to prevent buildup. Perform a deep clean at least once a month for heavily used saunas.
3. Can You Use Regular Household Cleaners?
Avoid harsh chemicals like bleach or ammonia. These can damage the wood and leave harmful residues that might react with heat.
4. Should You Clean After Every Use?
Yes. Wiping down the benches and walls after every session prevents sweat stains, odors, and bacteria from accumulating.
5. Removing Sweat Stains from Sauna Benches
Create a paste using baking soda and water. Apply it to the stains, let it sit for 15 minutes, and scrub gently. Rinse with a damp cloth.
6. Eliminating Odors
Mix a solution of equal parts water and vinegar. Spray it on surfaces, let it sit for a few minutes, and wipe clean. This neutralizes odors naturally.

7. Is Vinegar Effective?
Yes, vinegar is a natural disinfectant and deodorizer. Use it sparingly and rinse thoroughly to avoid a lingering smell.
8. Using Hydrogen Peroxide
Hydrogen peroxide is effective for tough stains. Dilute it with water, apply to the stained area, and wipe clean after a few minutes.
9. Should You Sand the Wood?
If stains or roughness persist, lightly sand the surface with fine-grit sandpaper. Always sand in the direction of the grain to maintain the wood’s integrity.
10. Oiling or Treating Sauna Wood
Avoid oiling the wood, as it can trap heat and odors. Instead, leave the wood untreated to allow it to breathe and stay fresh.
11. Disinfecting Sauna Wood Regularly
Disinfect once a month with a gentle solution of water and tea tree oil. It’s both antibacterial and safe for sauna wood.

12. Tools for Cleaning Sauna Wood
- Soft Brushes: For gentle scrubbing.
- Microfiber Cloths: To wipe and polish surfaces.
- Sponges: For applying cleaning solutions evenly.
13. Rinsing and Drying Sauna Wood
After cleaning, wipe surfaces with a damp cloth to remove any residue. Dry thoroughly with a towel or leave the sauna door open to air dry.
Using Essential Oils for a Fresh Scent
Add a few drops of essential oil like lavender or eucalyptus to your cleaning solution. This leaves a pleasant aroma without harming the wood.
Final Thoughts
Routine care ensures your sauna remains clean, inviting, and long-lasting. By following these steps, you’ll preserve the wood’s natural beauty and create a safe, hygienic environment for every session.
