How to Clean a Barrel Sauna

Even though an outdoor barrel sauna is highly sustainable, it still needs regular cleaning. 

Outdoor barrel saunas have become extremely popular recently. This is because they offer better heat distribution, plenty of health benefits, and require less maintenance. However, even though an outdoor barrel sauna is highly sustainable, it still needs regular cleaning. 

This article will reveal some vital cleaning and maintenance tips. 

How to clean the inside of an outdoor barrel sauna

Even though an outdoor barrel sauna is installed in a private residence for the homeowners' personal use, they should keep it clean like it's open to the public. After all, a sauna provides a peaceful, relaxing environment. It won't be as effective if it's dirty and cluttered with trash. 

Homeowners should clean their feet every time they want to use the sauna. Doing this prevents dirt and sweat build-up, which can lead to mold. They can also shower before coming into the sauna. When in use, it's best to sit on towels rather than directly on the wood. 

If it comes to cleaning the inside of an outdoor barrel sauna, here's what homeowners can do:

  • After using the sauna, they should wipe the benches with a soft towel. Doing this prevents moisture from sticking to the benches, which prolongs the sauna's lifespan. 

  • Remove any trash after each session. 

  • Dust and lose debris should be vacuumed or swept away. 

  • If there are any stains on the benches, homeowners can use warm water and a mild cleaning solution to remove them. 

  • Check the inside of the sauna for cracks and water seepage.

  • Clean the sauna stones. 

Try to avoid:

  • Leaving wet towels on the benches or floor.

  • Varnishing the inside of the sauna.

  • Using cleaning products that contain harsh chemicals.

  • Painting or staining the interior wood. 

How to clean the outside of an outdoor barrel sauna

Keeping the sauna's exterior clean is extremely important, especially for homeowners in a cold climate. Due to the moisture generated by challenging weather conditions and sunlight, the wood can weather over time. 

Here are different ways to keep the exterior of the sauna clean and well-maintained:

  • Treat the outer planks with wood-penetrating oil. Note that this oil may slightly change the color of the wood. 

  • Power-wash the exterior using a low-pressure, wide-patterned wash setting. Doing this will remove any stains and make the wood look brand-new. 

  • Ensure the door and the vents are clean and working correctly. 

  • Use a UV inhibitor when staining the exterior to prevent fading from the sunlight.

  • Regularly check the exterior for damage.
