Tips for Cleaning and Maintaining Your Indoor Sauna

For health enthusiasts who treasure wellness within the comfort of their homes, an indoor sauna is a sanctuary for relaxation and health. Properly cleaning and maintaining your indoor sauna not only extends its life but also enhances your wellness experience. Here’s a comprehensive guide to keeping your sauna in pristine condition.

How to Clean and Maintain Your Indoor Sauna

How to Clean Indoor Saunas

  1. Sweep and Vacuum: Begin by removing loose particles. Use a vacuum cleaner to extract dust and debris, then sweep any remaining particles from corners and hard-to-reach areas. Ensure the tools you use are gentle on the wood to prevent scratches.
  2. Scrub and Remove Stains: After vacuuming, tackle the wood and seating areas. Apply a mild detergent or natural cleaning solution (like bicarbonate paste or a vinegar and warm water mix) to damp cloths or sponges. Gently rub the wood surface to lift stains, rinse thoroughly, and allow it to air dry. For stubborn stains, lightly sand the area with fine-grit sandpaper before rinsing.
  3. Disinfect Ventilation Areas: Clean the interior aspects of the sauna, including the heater, stones, and ventilation areas. Natural products like lemon juice work well for this task. Apply with a sponge, rinse with water, and let dry.
  4. Refresh the Air: To avoid the unpleasant odors that chemical cleaners can leave behind, finish by refreshing the sauna with natural fragrances to create a welcoming atmosphere.
  5. Routine Maintenance Checks: Regularly inspect and clean crucial components such as heaters and stones to prevent the buildup of dirt and ensure efficient operation.

Tips to Maintain Your Indoor Sauna

Wood Care: Protect wooden surfaces with a breathable wood preservative to enhance resistance to dirt and moisture. This also enriches the wood's natural colour and makes cleaning easier. Avoid using harsh disinfectants or pressure washing, as these can damage the wood.

Ventilation: After cleaning, leave the sauna to dry with good ventilation. Open air vents and leave the door slightly ajar to circulate air and prevent moisture buildup.

User Guidelines: Encourage sauna users to sit on towels to protect the wood from sweat stains. Advise against wearing wet swimsuits and consider using seat covers for additional protection.

Drying: If your sauna design allows, lift benches after use to enable better drying. Keeping the interior dry prevents mold and mildew growth.

Maintaining Infrared Saunas vs. Traditional Saunas

Infrared saunas require slightly different maintenance than traditional saunas due to their unique heating elements. While the cleaning process for the wood and seating areas remains similar, attention should be given to the infrared panels:

  • Infrared Panels: Gently wipe the panels with a soft, dry cloth to remove dust. Avoid using water or cleaners directly on the panels to prevent damage.
  • Electrical Components: Regularly check electrical connections for any signs of wear or damage to ensure the infrared technology functions correctly.

Both sauna types benefit from routine maintenance, but the key difference lies in the care of their specific heating systems. Traditional saunas may require more frequent ventilation and heater stone cleaning, while infrared saunas necessitate careful handling of the delicate panels.


Maintaining your indoor sauna, whether it's an infrared model or a traditional steam sauna, is crucial for ensuring a safe and enjoyable wellness experience. Regular cleaning and adherence to maintenance tips will keep your sauna a cherished part of your home wellness routine for years to come. Remember, a well-maintained sauna is the cornerstone of any holistic wellness practice, embodying the Meubilair ethos of harmonising luxury and health.
