As a supplier of Cedar Outdoor Sauna, I understand the allure and relaxation that an outdoor cedar sauna brings. Cedar, with its natural beauty, durability, and aromatic properties, is a popular choice for outdoor saunas. However, to maintain its functionality, appearance, and longevity, regular cleaning is essential. In this blog, I'll share comprehensive steps on how to clean a cedar outdoor sauna properly.

Pre - cleaning Preparations

Before you start the actual cleaning process, there are a few important preparatory steps to take. First, ensure that the sauna is completely cooled down. Operating at high temperatures, a sauna can retain heat for a significant period. Cleaning a hot sauna not only poses a burn risk but can also cause the cleaning agents to evaporate too quickly, reducing their effectiveness.

Next, gather all the necessary cleaning supplies. You'll need a soft - bristle brush, a mild wood cleaner (preferably one specifically formulated for cedar), a bucket of warm water, a microfiber cloth, and a vacuum cleaner with a soft brush attachment. Avoid using harsh chemicals, abrasive cleaners, or steel wool, as these can damage the delicate cedar wood.

Step 1: Remove Debris

The first step in cleaning your cedar outdoor sauna is to get rid of any loose debris. Use the vacuum cleaner with the soft brush attachment to gently remove dust, dirt, and any small particles from the benches, walls, and floor of the sauna. Pay special attention to the corners and crevices where debris tends to accumulate. This initial vacuuming helps to prevent scratching the wood surface during the subsequent cleaning steps.

Step 2: Prepare the Cleaning Solution

In the bucket of warm water, add the mild wood cleaner according to the manufacturer's instructions. Stir the solution gently until it is well - mixed. Remember, cedar is a natural wood, and using a gentle cleaner will help preserve its integrity and natural oils.

Step 3: Clean the Benches

Dip the soft - bristle brush into the cleaning solution and start scrubbing the benches. Work in small sections, applying gentle pressure to remove any stains, sweat marks, or dirt. Be careful not to scrub too hard, as this can damage the wood. After scrubbing each section, use the microfiber cloth to wipe away the dirty cleaning solution. Rinse the cloth frequently in the clean water to avoid spreading dirt back onto the benches.

Step 4: Clean the Walls

The walls of the cedar outdoor sauna also need thorough cleaning. Repeat the process used for the benches. Use the soft - bristle brush and the cleaning solution to gently scrub the walls, paying attention to any areas that may be particularly dirty. Cedar walls can absorb moisture and dirt over time, so it's important to clean them regularly to maintain their appearance and prevent mold growth. As you clean, make sure to wipe away the cleaning solution with the microfiber cloth.

Step 5: Clean the Floor

The floor of the sauna is often subject to the most wear and tear. Use the soft - bristle brush and the cleaning solution to scrub the floor, working in a back - and - forth motion. Due to the likelihood of water pooling on the floor, it may require a bit more scrubbing to remove stubborn dirt and stains. After scrubbing, use the microfiber cloth to dry the floor thoroughly. A wet floor can lead to mold and mildew growth, which can be harmful to both the wood and your health.

Step 6: Clean the Sauna Heater

The sauna heater is a crucial component of your cedar outdoor sauna. However, it requires special care when cleaning. First, make sure the heater is completely turned off and cooled down. Use a dry microfiber cloth to gently wipe away any dust or debris from the surface of the heater. Avoid getting the heater wet, as this can cause electrical problems. If there are any stubborn stains on the heater, consult the manufacturer's instructions for appropriate cleaning methods.

Step 7: Disinfect the Sauna

After cleaning, it's a good idea to disinfect the cedar outdoor sauna to kill any bacteria or germs. You can use a natural disinfectant, such as a mixture of water and vinegar. Spray the disinfectant lightly on the benches, walls, and floor, and then wipe it off with a clean microfiber cloth. This step helps to keep your sauna clean and hygienic, making your sauna sessions more enjoyable and healthy.

Step 8: Let the Sauna Dry

Once you have completed the cleaning and disinfection process, leave the sauna door open to allow it to dry thoroughly. Proper ventilation is essential to prevent moisture from being trapped inside the sauna, which can lead to mold and mildew growth. You can also use a fan to speed up the drying process. Make sure the sauna is completely dry before using it again.

Step 9: Maintain Regular Cleaning Schedule

To keep your cedar outdoor sauna in top condition, it's important to establish a regular cleaning schedule. Depending on how often you use the sauna, a thorough cleaning every one to two months is recommended. In addition to the deep cleaning, you can perform light maintenance, such as vacuuming and wiping down the surfaces, on a weekly basis.

Additional Tips for Cedar Outdoor Sauna Maintenance

  • Protect from the Elements: If your cedar outdoor sauna is exposed to the elements, consider using a sauna cover when it's not in use. This can protect the wood from rain, snow, and UV rays, which can cause damage over time.
  • Check for Damage: Regularly inspect the sauna for any signs of damage, such as cracks, splits, or loose boards. Address any issues promptly to prevent further damage.
  • Re - oil the Wood: Over time, the natural oils in the cedar wood will wear off. You can apply a food - grade cedar oil to the benches and walls every few months to restore the wood's natural luster and protect it from drying out.

Conclusion

Cleaning a cedar outdoor sauna is a straightforward process that, when done regularly, can significantly extend the life of your sauna and enhance your sauna experience. By following the steps outlined in this blog, you can keep your Cedar Outdoor Sauna clean, hygienic, and looking beautiful for years to come.
