Sauna Maintenance Guide: Extend Lifespan, Ensure Safety, Keep Every Session Like New

As a wellness device for homes or commercial spaces, saunas—whether traditional wooden dry saunas or infrared models—require regular maintenance. Proper care not only extends their lifespan (well-maintained wooden saunas can last over 10 years, while infrared saunas’ core components can serve 8–12 years) but also prevents problems like odors, cracks, and heating failures, ensuring safe and comfortable use. Below is a practical maintenance guide covering daily basic care, regular deep maintenance, material-specific precautions, and common issue troubleshooting.

I. Daily Maintenance: 3 Must-Do Steps After Each Use to Prevent Small Issues

Daily maintenance is the core of sauna care, focusing on "cleaning, ventilation, and inspection." Simple as it is, it avoids 80% of common faults.

1. Cleaning: Use the Right Tools to Avoid Damaging Materials

Wooden Saunas (Dry/Traditional Models): After use, wait for the temperature to drop below 40°C (high temperatures + wiping can warp wood). Wipe the inner walls, seats, and floor with a slightly damp soft cotton cloth or natural fiber rag—only use clean water. Never use chemical cleaners like dish soap or body wash (they strip wood of its natural oils, causing cracking, fading, and residual odors). For sweat or stains, gently wipe with a small amount of white vinegar (a natural, non-irritating cleaner), then pat dry with a cloth.

Infrared Saunas (With Metal/Plastic Parts): Clean wooden parts as above. For infrared heating panels, control panels, and glass doors: Wipe heating panels with a dry cloth (prevent water from seeping in and causing short circuits); use a "half-dry soft cloth" to clean control panels (avoid liquid entering circuits); wipe glass doors with a small amount of non-corrosive glass cleaner to remove water stains and maintain transparency.

Sauna Stones (Essential for Traditional Models): After each use, gently brush off dust or debris from stones with a dry brush. White water stains from splashed water need no special cleaning (they don’t affect heating), but avoid excessive dirt buildup (it reduces steam efficiency).

2. Ventilation: Rapidly Remove Moisture to Prevent Mold and Rust

Natural Ventilation: Immediately open the sauna door (or air vent) after use to release humid air. Open room windows or exhaust fans to speed up airflow—moisture is a wooden sauna’s "worst enemy." Long-term dampness causes mold, black spots, and rust on infrared saunas’ metal parts.

Auxiliary Drying: In high-humidity environments (e.g., southern China’s rainy season), place 1–2 bags of desiccant (e.g., silica gel, replaced regularly) inside the sauna, or use a small dehumidifier (placed over 1 meter away to avoid direct blowing). Close the door only after the interior is completely dry (wood feels dry to the touch).

3. Inspection: 1-Minute Check to Spot Hidden Risks

Circuit Check (Infrared/Electric-Heated Traditional Models): After use, check if the control panel lights work normally (no flickering or error codes). Inspect power cords and plugs for damage or overheating signs—if plugs feel hot or cords crack, stop use immediately and contact a professional to avoid short circuits.

Structure Check: Look for loose wooden joints (e.g., seat screws, wall seams) and test if glass door hinges move smoothly. Add 1 drop of dedicated lubricating oil to sticky hinges to prevent rust. Replace cracked sauna stones promptly (broken stones may block the heater, causing local overheating).

II. Regular Deep Maintenance: 4 Tasks by Cycle to Extend Core Component Life

Beyond daily care, schedule deep maintenance weekly, monthly, and quarterly to focus on "wood care, core part checks, and detail reinforcement."

1. Weekly: "Oil" Wooden Parts to Prevent Cracking

For wooden saunas (and wooden parts of infrared saunas): Once a week, when the sauna is completely dry, apply a small amount of sauna-specific natural wood wax oil (e.g., linseed oil, beeswax oil—odorless and heat-resistant) to a soft cloth. Wipe the wood surface evenly (inner walls, seats, door frames). Wood wax oil replenishes lost oils and forms a protective layer, preventing cracking and warping from long-term heat and dryness.

Note: Use only a thin layer of oil (excess feels greasy). Wait 2–4 hours for full absorption before using the sauna.

2. Monthly: Inspect Core Components for Stable Performance

Traditional Models (Wood-Burning/Electric Heaters): Clean dust from heater vents with a dry brush (blocked vents reduce heating efficiency). Test if electric heater thermostats work (check if they heat up and maintain temperature across different settings).

Infrared Models: Focus on infrared heating panels—turn on power and feel the panel surface (it should heat evenly, with no hotspots or cold areas). If heating is uneven, stop use immediately (it may indicate aging panels or poor circuit contact; professional repair is needed). Wipe power plugs and sockets for oxidation (use a dry cloth to prevent poor contact).

Drainage System (If Equipped): Use a thin wire (or dedicated unclogger) to clear sauna floor drains monthly. Hair or dust buildup causes waterlogging, which rots wood bases.

3. Quarterly: Full Reinforcement + Dead-Corner Cleaning to Prevent Structural Issues

Structure Reinforcement: Tighten loose screws or buckles (especially on load-bearing parts like seats and beams) with a matching screwdriver—don’t over-tighten to avoid wood cracking. Replace aging or peeling glass door seals (seals prevent heat loss; worn seals slow heating and waste energy).

Dead-Corner Cleaning: Clean hidden areas like under heating panels, seat bottoms, and wall corners with a vacuum (soft brush attachment) to remove dust and hair. These spots breed bacteria and block heat dissipation if dirty. Wipe remaining dust with a dry cloth.

III. Material-Specific Precautions: Avoid Mistakes for Wooden vs. Infrared Saunas

Different sauna materials require targeted care—avoid "one-size-fits-all" mistakes.

1. Wooden Saunas: Avoid 3 "Wood-Damaging" Behaviors

Mistake 1: Pouring water or using excessive water for cleaning at high temperatures—hot wood swells quickly and shrinks when cool, leading to cracks.

Mistake 2: Long-term exposure to sunlight or heat sources (e.g., radiators, AC vents)—wood loses moisture rapidly, causing drying and warping. Install saunas away from heat and direct sunlight.

Mistake 3: Cleaning with hard brushes or steel wool—they scratch wood surfaces, damage protective layers, and make stains harder to remove.

2. Infrared Saunas: Protect Circuits and Heating Components

Absolute No-No: Let water touch infrared heating panels, control panels, or power cords—water causes short circuits, leaks, and safety hazards.

Avoid Impact: Infrared panels are fragile—don’t hit them with hard objects (e.g., towel racks, hooks) or place heavy items (e.g., suitcases, fitness equipment) inside the sauna.

Long-Term Inactivity (Over 1 Month): Unplug the power cord and cover the sauna with a dust cover to prevent dust buildup on panels and circuits.

IV. Common Issue Troubleshooting: Fix Small Problems Yourself

Try these solutions first for common issues—contact a professional only if problems persist.

1. Wooden Sauna Odors (Moldy/Sharp Smells)

Cause: Long-term dampness leading to mold, or residual chemical cleaners.

Solution: Ventilate the sauna for 24 hours. Place 2–3 sliced lemons (or bowls of white vinegar, which absorbs odors) inside, seal for 6 hours, then ventilate again. For mold spots, wipe with a 1:1 mixture of white vinegar and water, dry, and reapply wood wax oil.

2. Infrared Sauna Slow Heating/Uneven Temperature

Cause: Dust on heating panels, worn seals, or faulty thermostats.

Solution: Clean dust from panels and replace aging seals. Test the thermostat—set it to high and check if it reaches 60°C+ within 30 minutes. If not, the thermostat or panel may be faulty (need professional repair).

3. Brittle Sauna Stones/Noises When Heated

Cause: Low-quality stones (not heat-resistant) or internal cracks from long-term use.

Solution: Replace with sauna-specific heat-resistant stones (e.g., basalt, volcanic rock—hard and heat-tolerant). Don’t overfill the heater (leave gaps for even heat distribution) to avoid stone collisions and cracking.
