Sauna stones play a crucial role in ensuring a high-quality sauna experience. They store and release heat efficiently, providing consistent warmth and generating steam when water is poured over them. However, to maintain their effectiveness and prolong their lifespan, proper care is essential. Regular maintenance not only ensures a better sauna experience but also enhances the longevity of the sauna furnace.

1. Choose the Right Sauna Stones

Before discussing maintenance, selecting the right sauna stones is key. High-density stones such as peridotite, olivine, and vulcanite are best for heat retention and durability. Avoid using soft or porous stones as they may crack under extreme temperatures. Additionally, choose stones of different sizes to allow proper airflow around the sauna furnace, ensuring even heat distribution.

2. Regular Cleaning to Remove Residue

Over time, sauna stones accumulate dust, dirt, and mineral deposits, which can reduce their efficiency. To keep them clean:

• Remove the stones from the sauna furnace every few months.
• Rinse them thoroughly with water to remove dirt and debris.
• Use a brush to scrub off any stubborn residue.
• Let the stones dry completely before placing them back in the furnace.

Avoid using soap or chemical cleaners, as these substances may release harmful fumes when the stones are heated.

3. Inspect for Cracks and Wear

Frequent heating and cooling cycles can cause sauna stones to crack or break over time. Damaged stones can affect heat distribution and may even lead to overheating in certain areas of the sauna furnace. To prevent this:

• Inspect the stones at least twice a year.
• Remove any cracked, chipped, or crumbling stones.
• Replace them with fresh stones to maintain optimal performance.

Using cracked sauna stones can lead to uneven heat distribution, reducing efficiency and comfort in your sauna sessions.

4. Properly Arrange the Stones

How you stack sauna stones inside the sauna furnace directly affects airflow and heating efficiency. When placing stones:

• Avoid stacking them too tightly, as this can restrict airflow and reduce heating efficiency.
• Arrange them with gaps in between to allow for even heat distribution.
• Use larger stones at the bottom and smaller stones at the top for better airflow.

Proper stacking improves the overall sauna experience by ensuring consistent heat output and steam generation.

5. Control Water Usage

Pouring water over sauna stones is a common practice to create steam and enhance the sauna experience. However, excessive water use can cause problems such as:

• Mineral buildup from hard water, which reduces heat efficiency.
• Cracking of stones due to sudden temperature changes.
• Damage to the sauna furnace if water seeps into electrical components.

To prevent these issues, use only a moderate amount of water and ensure it is poured evenly over the stones.

6. Replace Sauna Stones Periodically

Even with proper maintenance, sauna stones wear out over time due to continuous heating and cooling cycles. It’s recommended to replace them every 1 to 2 years, depending on usage. When replacing stones:

• Remove old stones and clean out any dust or debris from the sauna furnace.
• Rinse and dry new stones before placing them.
• Arrange them properly for maximum airflow and efficiency.

7. Keep the Sauna Furnace in Good Condition

Maintaining your sauna furnace is just as important as maintaining the stones. Regularly check for any signs of rust, electrical issues, or clogged vents. A well-maintained furnace ensures that sauna stones can function efficiently and provide a consistent heat output.

Conclusion

Sauna stones are an essential component of any sauna setup, and proper maintenance is key to enjoying a safe and effective sauna experience. Regular cleaning, inspection, and replacement of stones help in maintaining optimal heat distribution and prolonging the life of the sauna furnace. By following these simple maintenance steps, you can ensure your sauna continues to provide relaxation and health benefits for years to come.
