How to Clean an Infrared Sauna

Infrared saunas & hygiene

Infrared saunas induce deep sweating that naturally deposits oils, skin cells, and impurities onto benches, walls and glass. Regular sauna cleaning and infrared sauna maintenance are essential to preserve a hygienic environment and protect the wood surfaces used in Sunlighten saunas. 

Choosing cleaning products

Sunlighten offers a  purpose-made, non-toxic infrared sauna cleaning solution that is safe on both interior wood and glass surfaces—and is more reliable than generic or multi-purpose household cleaners that may damage wood or void warranties. 

• The Natural Cleaning Kit contains a plant-based Sauna Cleaner, Glass Cleaner, a microfiber cloth, and sanding sponge for gentle but effective cleaning and polishing.  
• For specialized care, the kit includes separate Natural Wood Cleaner and Natural Glass Cleaner options, each vegan, fragrance-free, and gentle on surfaces.  

These cleansers are ideal for infrared sauna cleaning and infrared sauna care, offering antibacterial, antimicrobial, and mold-prevention without harsh chemical residues. 

Helpful tools for sauna cleaning include:

• Microfiber cloths – Ideal for gently wiping down wood and glass surfaces without scratching or leaving lint. 
• Soft-grit sanding sponges (around 150 grit) – Useful for lightly sanding away sweat stains or residue buildup on wood surfaces. 
• Detail brushes or soft sponges – Help reach tight corners, control panels, and seams without damaging materials. 

These tools support effective infrared sauna cleaning while preserving the integrity and appearance of your sauna’s interior. 

Deep cleaning an infrared sauna 

For scheduled maintenance: 

• Remove linens and vacuum corners or crevices. 
• Wipe surfaces (wood and glass) thoroughly using diluted cleaners from the kit. 
• Treat persistent stains or residue with the 150-grit sanding sponge. 
• Buff wood with a dry microfiber cloth to eliminate sanding dust and restore texture. 
• Inspect heater panels (when cool) and gently wipe them with a microfiber towel or soft cloth —never apply chemicals directly to heating elements. 

These deep cleaning steps are best done every 1–2 weeks, with monthly sanding using an 80-grit sanding sponge if heavily used.
