Saunas require regular cleaning to maintain hygiene, scent, and wood longevity. A well-planned cleaning routine helps prevent mold, mildew, and odor buildup while preserving the natural warmth that sauna users expect.
This guide provides a practical, step-by-step approach, using common sauna-cleaning tools and products designed for wood surfaces and benches. Readers will find actionable steps, safety notes, and troubleshooting tips that apply to most home sauna setups.
Quick Answer
Clean after regular use with a cedar-focused cleaner, scrub benches and walls with appropriate brushes, wipe surfaces with a mild cleaner, dry thoroughly, and re-check seals and vents for any signs of moisture-related issues. Always follow product labels and ventilation guidelines.
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
Ensure the sauna is fully cooled before cleaning. Ventilate the room well to avoid inhaling cleaning fumes. Wear protective gloves and eye protection as needed. Time estimates vary, but plan for 30–60 minutes for a thorough clean, plus extra time for drying. Do not use harsh bleach or ammonia on cedar surfaces, as it can damage the wood finish.
Step-By-Step: How To Clean A Sauna
- Remove loose debris from benches and floors, using a dry cloth or brush.
- Spray a cedar-safe cleaner on benches, allowing it to sit for a few minutes to lift oils.
- Scrub benches with the sauna wood scrub brush stiff bristles to break up buildup.
- Wipe benches clean with a damp cloth, then dry with a towel to prevent moisture absorption.
- For walls, use a non-scratch nylon scrub pad to gently remove surface dirt without scratching.
- Wipe all horizontal surfaces again and ensure seams and joints are clean.
- Inspect for mold or mildew in corners or crevices; address any growth promptly with the appropriate cleaner.
- Clean the floor area, paying attention to any drainage gaps or vent openings.
- Use a stainless steel sauna scraper tool to remove any excess moisture from metal fixtures or trims.
- Allow surfaces to air-dry completely; avoid closing the sauna door until dry to prevent moisture buildup.
- Reopen the room and return furniture to its place, ensuring ventilation remains active during reuse.
- Perform routine cleaning after heavy use or following noticeable odor changes to maintain a fresh environment.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Persistent damp smell | Inadequate drying | Increase ventilation and extend drying time | Wipe thoroughly and air out after cleaning |
| Discoloration on benches | Undiluted cleaner or improper scrubbing | Rinse with water, re-clean using cedar-safe products | Test cleaner on a small area first |
| Scratches on walls | Overly aggressive scrubbing | Switch to non-scratch pads and light pressure | Use appropriate brushes and pads |
| Residual soap film | Incomplete rinsing | Rinse multiple passes with clean water | Finish with a dry wipe |
Common Mistakes
- Using harsh chemical cleaners on cedar wood
- Failing to dry surfaces fully after cleaning
- Over-wetting the wood, which can lead to warping
- Ignoring corners and joints where mold can form
Tips For Best Results
- Clean on a regular schedule to prevent buildup rather than deep-cleaning infrequently
- Use products specifically formulated for sauna wood to protect the finish
- Maintain good ventilation during and after cleaning to speed drying
- Inspect seals, vents, and heater components periodically for moisture damage
Call A Professional
Consider a professional if there is extensive mold growth, structural wood damage, or persistent odors that resist standard cleaning methods. Seek help if you notice warping, cracks, or corrosion around metal fittings, or if cleaning requires specialized equipment beyond routine maintenance.

Buying Guide
When selecting sauna cleaning supplies, consider size compatibility with your sauna, surface types, and ease of use. Look for cedar-safe formulations, non-abrasive pads, and tools designed for hot, damp environments. Consider the noise level and storage space for cleaning kits, and ensure products are suitable for bench and wall materials. A well-chosen cleaning kit helps maintain wood tones, resists odors, and extends the life of sauna components.
