Maintaining a clean sauna helps preserve wood integrity, prevent odors, and keep the space hygienic for every use. This guide outlines a straightforward, safe approach to cleaning saunas at home, using common tools and purpose-built products to protect wood and metal surfaces.
Following a simple routine can extend the life of cedar benches, walls, and floors, while reducing the buildup of grime and mineral deposits from steam and sweat. The steps below are designed for typical residential saunas and can be adapted for different materials and finishes.
Quick Answer
Best practice: clear the room, use mild cleaners, avoid harsh chemicals, and rinse thoroughly. Sanitize benches and walls weekly, and perform a deeper clean every few months to prevent resin buildup and odor.
What You’ll Need
- Cedar Sauna Cleaner Spray For Benches
- Sauna Wood Scrub Brush Stiff Bristles
- Steam Sauna Cleaning Kit
- Non-Scratch Nylon Scrub Pad For Sauna Walls
- Stainless Steel Sauna Scraper Tool
Before You Start
Prepare the space by removing all accessories and ensuring the room is dry before cleaning. Ventilate if possible to avoid inhaling fumes from cleaners. Test a small, inconspicuous area on wood to confirm there is no staining or color change. Time estimate: 20–40 minutes for a standard radius addition, longer for larger installations. Key cautions: never use bleach or abrasive household cleaners on unfinished cedar; avoid harsh solvents that can degrade wood and sealants.
Step-By-Step: How To Clean A Sauna
- Remove loose debris – Wipe benches and floors with a dry cloth to remove hair, dust, and sweat residues.
- Apply a gentle cleaner – Lightly mist the cedar benches and walls with cedar sauna cleaner spray for benches or a pH-neutral cleaner designed for wood. Do not soak the wood.
- Scrub wood surfaces – Use the sauna wood scrub brush stiff bristles to lift stubborn grime from benches and backrests in the direction of the grain. Avoid aggressive scrubbing that could scratch the surface.
- Scrub walls with care – For walls, employ the non-scratch nylon scrub pad for sauna walls to gently remove mineral deposits and residues without gouging the wood.
- Rinse and wipe – Lightly dampen a clean cloth with water and wipe down surfaces to remove cleaner residue. Do not saturate wood; moisture is a key enemy in saunas.
- Clean crevices and heater area – Use the stainless steel sauna scraper tool to remove any hardened deposits around vents or heater housing without prying off seals.
- Dry thoroughly – Leave doors open and allow air to circulate until all surfaces are completely dry before reassembling accessories.
- Optional sanitizing cycle – If desired, run the steam function briefly with the door open to help sanitize, then repeat the wipe-down to remove any loosened residues.
- Regular maintenance – Establish a routine to wipe surfaces after heavy use and perform a deeper clean every 4–8 weeks, depending on usage.
- Inspect for wear – Check for cracked or softened wood and replace affected boards promptly to prevent further damage.
- Document maintenance – Keep a simple log of cleaning dates to stay consistent with preventive care.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent odor after cleaning | Insufficient drying; resin buildup | Increase drying time; re-clean with milder cleaner | Dry thoroughly after each use |
| Streaks on wood | Cleaner residue | Rinse and wipe with a clean damp cloth | Use minimal cleaner and light misting |
| Scratches on walls | Abrasive scrubbing | Switch to non-scratch pad; scrub lighter | Limit aggressive brushing |
| Warping boards | Excess moisture | Dry promptly; ensure good ventilation | Control humidity and keep surfaces dry |
Common Mistakes To Avoid
- Using bleach or harsh solvents on cedar.
- Soaking wood or allowing standing water on benches.
- Over-scrubbing, which can abrade the finish.
- Neglecting to dry the sauna after cleaning or use.
Tips For Best Results
- Clean with the grain of the wood to minimize scratching and to lift grime more effectively.
- Spot-clean high-use areas like seating lines more frequently than less-used panels.
- Test cleaners on an inconspicuous area before full application.
- Maintain proper ventilation during and after cleaning to speed up drying.
- Use purpose-built sauna care products to protect wood oils and resins.
Call A Professional
Seek a professional if wood appears warped, mold or mildew is clearly visible, or if the heater and electrical components need cleaning beyond basic surfaces. Stop using the sauna if there is persistent leakage, foul odors that don’t fade after cleaning, or any audible cracking sounds from the heater area.
FAQ
How often should I clean a sauna?

Buying Guide
When choosing sauna cleaning tools and accessories, consider size, materials, and compatibility with your sauna type. Size and layout influence how quickly a space can be cleaned; smaller saunas benefit from compact tools, while larger layouts may require longer-handled brushes. Noise level matters in quiet homes or spa setups, so select tools with soft bristles and non-metal parts to reduce clatter.
Energy efficiency relates to how often you run cleaning cycles that use the heater or steam. Choose tools that reduce the need for excessive moisture exposure. Controls should be simple and ergonomic, with comfortable grips and non-slip handles for safe operation.
Placement and storage are important: keep cleaning tools near the sauna but in a dry area to prevent mold growth. Compare kits that include a cedar-friendly cleaner, wood scrub brushes, nylon pads, and a scraper for hard-to-reach spots. For most homes, a balanced set that covers surface cleaning, grime removal, and edge scraping provides the best value and effectiveness.
