How to Clean a Portable Sauna (Without Compromising the Experience)
A portable sauna is more than just a wellness accessory—it’s a sanctuary of heat, silence, and ritual. For Kyfe clients, it’s also a symbol of design, quality, and intention. And just like any high-performance experience, the Kyfe Sauna deserves exceptional care. Whether you’ve just enjoyed a rejuvenating sauna session by the lake or hosted a weekend gathering in your backyard, knowing how to clean your portable sauna properly ensures every moment that follows is as powerful as the first.
This guide walks you through exactly how to clean a portable sauna—specifically a wood-burning model like the Kyfe Sauna. From the furnace to the sauna rocks to the sauna’s interior, we’ll cover every step of the cleaning process to maintain peak performance, ensure safety, and preserve the elevated essence of your ritual.
Why Regular Maintenance Is Essential for Sauna Longevity
The Difference Between Wood-Burning and Infrared Waves
Unlike infrared saunas, which rely on infrared waves to gently heat the body, wood-burning saunas like Kyfe offer a more powerful, elemental experience. They reach over 200°F and produce true steam—löyly—by pouring warm water over heated rocks. This makes regular maintenance not only important for cleanliness but crucial for optimal performance.
The Risks of Skipping Regular Cleaning
Without regular cleaning, excess moisture, dust, and soot can collect in key areas—impacting airflow, weakening materials, and even encouraging mildew growth inside the sauna tent. Over time, this neglect can degrade your sauna’s heat quality, create safety risks, and affect the purity of your session. Thoughtful upkeep preserves a hygienic environment and supports both physical and mental relaxation.
