Buying a sauna is an investment in your home and your well-being—but keeping it in great condition doesn’t require hours of maintenance.

Many first-time sauna owners wonder if they need to scrub it after every use or use special cleaning products. Fortunately, the answer is much simpler. With a few easy habits and occasional deep cleaning, your sauna can stay fresh, hygienic, and beautiful for many years.

Whether you own an outdoor barrel sauna, a modern backyard sauna, or an indoor sauna, here’s everything you need to know about keeping it in top shape.

Why Cleaning Your Sauna Matters

Every sauna session introduces heat, moisture, and sweat into the space. While quality sauna woods like Canadian red cedar naturally resist mold and bacteria, regular maintenance helps preserve the wood’s appearance and keeps every session enjoyable.

A clean sauna also:

• Extends the life of the wood
• Prevents stains and odors
• Improves hygiene
• Keeps your heater working efficiently
• Protects your investment

The good news? Most maintenance takes only a few minutes.

How Often Should You Clean Your Sauna?

After Every Use

The easiest way to keep your sauna clean is by building a few simple habits into your routine.

After each session:

• Leave the door open for 20–30 minutes to let moisture escape.
• Remove towels and accessories.
• Wipe away any excess moisture on the benches if needed.
• Sweep out dirt or leaves that may have been tracked inside.

These quick steps help prevent moisture buildup and keep the wood dry.

Weekly

If you use your sauna several times a week, give it a light cleaning once a week.

This includes:

• Sweeping or vacuuming the floor
• Wiping benches with a damp microfiber cloth
• Cleaning door handles and frequently touched areas
• Checking around the heater for dust or debris

Avoid soaking the wood. A lightly damp cloth is all you need.

Every Few Months

Every three to six months, spend a little extra time giving your sauna a deeper clean.

Inspect for:

• Sweat stains
• Dust behind benches
• Loose hardware
• Dirt in corners
• Wear around the heater and sauna stones

For outdoor saunas, also check the roof and exterior for leaves, pollen, or weather-related buildup.

The Best Way to Clean a Sauna

One of the biggest mistakes homeowners make is using harsh household cleaners.

Instead, stick to simple cleaning supplies:

• Warm water
• Mild soap
• Soft microfiber cloths
• Soft-bristle brush
• Fine-grit sandpaper for stubborn stains

If you notice darker areas on the benches from regular use, lightly sanding the surface with the grain of the wood can help restore its natural appearance.

Never use bleach, ammonia, or pressure washers inside your sauna, as they can damage the wood.

Simple Tips to Keep Your Sauna Cleaner

A few good habits can reduce how often you’ll need to deep clean your sauna.

• Shower before entering.
• Sit on a towel during each session.
• Avoid bringing food or sugary drinks inside.
• Remove outdoor shoes before entering.
• Let the sauna dry completely after every use.

These small habits go a long way toward protecting the wood and keeping your sauna fresh.

Common Sauna Maintenance Mistakes

Avoid these common mistakes that can shorten your sauna’s lifespan:

• Using harsh chemical cleaners
• Closing the sauna immediately after use without ventilation
• Allowing water to pool on benches
• Ignoring small stains until they become permanent
• Forgetting to inspect the heater and sauna stones

Regular maintenance is much easier—and less expensive—than repairing neglected wood.
