Proper maintenance of the wooden interior of your sauna is essential for preserving its longevity and performance. As the wood absorbs and releases moisture, it requires specific care to ensure its durability and aesthetic appeal. Here are some tips for maintaining and treating the sauna walls and wood:

Cleaning Sauna Walls

To keep the sauna walls clean and free from dirt and grime, regularly wipe down the surfaces after each use. Use a damp brush or a mild dish detergent to remove any sweat or residue. Avoid using harsh chemicals, abrasive cleaners, paint, varnish, stain, or sealants on the interior walls, as these can interfere with the wood’s ability to breathe. Instead, opt for gentle cleaning methods that preserve the natural beauty of the wood.

Treating Sauna Wood

To maintain the health and appearance of the sauna wood, periodic treatment is recommended. After cleaning the sauna walls, allow them to dry completely before applying any treatments. Depending on the type of wood, you can use sauna oils or wood sealers specifically designed for saunas. These products help nourish the wood, protect it from moisture, and enhance its natural color. Follow the manufacturer’s instructions for application, and reapply the treatment as needed to keep the wood in optimal condition.

By taking proper care of the wooden interior, you can prolong the lifespan of your sauna and ensure a pleasant and inviting environment for relaxation and rejuvenation.
