A sauna is exposed to heat, sweat, moisture, and regular use, so keeping it clean is an important part of home sauna maintenance.

Regular cleaning can help keep the interior looking fresh, reduce unpleasant odors, and protect the wood and other sauna components over time.

Fortunately, cleaning a sauna does not need to be complicated. With a simple routine and the right cleaning methods, most homeowners can keep their sauna in good condition without spending a lot of time on maintenance.

This guide explains how to clean a home sauna, including the benches, walls, floor, door, and other commonly used areas.

Why Should You Clean a Sauna Regularly?

Sweat and moisture can accumulate on sauna benches and other surfaces during normal use.

Without regular cleaning, these areas can develop:

• Unpleasant odors
• Stains
• Dirt buildup
• Discoloration
• Surface wear

Regular maintenance also gives you an opportunity to inspect the sauna for loose boards, damaged surfaces, or other problems.

A clean sauna is generally more pleasant to use and easier to maintain over the long term.

How Often Should You Clean a Sauna?

The ideal cleaning schedule depends on how frequently the sauna is used.

For a home sauna used regularly, a simple routine can include:

After each use

• Allow the sauna to dry
• Remove towels and personal items
• Wipe up visible moisture

Weekly

• Wipe down benches and frequently touched surfaces
• Check the floor for dirt or debris

Every few weeks

• Give the interior a more thorough cleaning
• Check the benches, walls, door, and heater area

Periodically

• Inspect the sauna for signs of wear or damage
• Clean or maintain components according to the manufacturer’s instructions

If several people use the sauna regularly, more frequent cleaning may be appropriate.

Step 1: Let the Sauna Cool Down

Before cleaning, turn off the sauna heater and allow the room to cool completely.

Never clean around a hot heater or hot sauna stones.

Once the sauna has cooled, remove towels, accessories, and other items from the room.

This gives you clear access to the benches and floor.

Step 2: Remove Dust and Debris

Start by removing loose dirt and debris.

A soft brush or vacuum suitable for the surface can be useful for cleaning the floor and corners.

Pay particular attention to:

• Under benches
• Around the door
• Corners
• Floor edges
• Areas around the heater

Do not use excessive force on the wood.

Step 3: Clean the Sauna Benches

The benches are one of the most important areas to clean because they have frequent contact with the user’s skin.

Start with a clean, damp cloth.

Wipe the bench surfaces carefully and remove visible sweat marks or dirt.

For deeper cleaning, use a cleaning product specifically recommended for sauna wood.

Avoid soaking the benches with water.

Excess moisture can take longer to dry and may affect the wood over time.

Why Bench Cleaning Matters

Even when the sauna looks clean, benches can accumulate sweat and body oils through regular use.

Using a towel on the bench can reduce direct contact, but it does not eliminate the need for cleaning.

A regular bench-cleaning routine can help maintain both appearance and comfort.

Step 4: Clean the Walls

The interior walls generally need less frequent cleaning than the benches.

Use a soft cloth or sponge with an appropriate amount of water.

Gently wipe areas where dirt or moisture has accumulated.

Avoid aggressive scrubbing unless the manufacturer specifically recommends it.

The goal is to clean the surface without unnecessarily damaging the wood.

Step 5: Clean the Sauna Floor

The floor can collect dirt, dust, and moisture.

Sweep or vacuum loose debris first.

Then clean the floor using a method appropriate for the sauna’s flooring material.

If the sauna has a removable or washable floor surface, follow the manufacturer’s instructions for cleaning it.

Avoid leaving standing water inside the sauna.

Good drainage and adequate drying are important for long-term maintenance.

Step 6: Clean the Door and Handles

Sauna doors and handles are frequently touched, so they should be included in the cleaning routine.

Wipe the door handle and other frequently touched surfaces with a suitable cloth.

For glass doors, use a cleaning method appropriate for the glass.

Avoid products that may leave strong residues or are not suitable for the sauna environment.

Step 7: Clean Around the Heater

The area around the sauna heater should be kept free from dust, towels, and other objects.

Once the heater is completely cool, inspect the surrounding area.

If your sauna uses stones, follow the heater manufacturer’s instructions for inspecting and maintaining them.

Do not move or handle hot stones.

Also avoid applying cleaning chemicals directly to the heater or sauna stones unless the manufacturer specifically allows it.

Should You Wash Sauna Wood With Water?

A small amount of water may be appropriate for routine cleaning, but the wood should not be soaked.

Excessive moisture can make drying more difficult and may contribute to long-term wood problems.

Use a damp rather than saturated cloth for most light cleaning.

After cleaning, allow the sauna to dry thoroughly.

Can You Use Regular Household Cleaners?

It is better not to assume that ordinary household cleaners are suitable for a sauna.

Some cleaning products contain ingredients that may leave residues or produce odors when the sauna becomes hot again.

Instead, use products specifically recommended for sauna surfaces or follow the sauna manufacturer’s cleaning instructions.

When in doubt, check the care instructions for the specific wood and sauna model.

How to Remove Sauna Odors

A sauna can develop odors if sweat and moisture are not removed regularly.

To help keep the sauna smelling fresh:

• Remove damp towels after each use
• Allow the sauna to dry
• Clean benches regularly
• Keep the floor clean
• Maintain appropriate ventilation
• Avoid leaving personal items inside

Strong chemical fragrances are not necessary to keep a sauna fresh.

A clean and properly dried sauna should generally have a natural wood environment without excessive odors.

How to Keep Sauna Benches Looking Good

Benches receive a lot of wear because they are used frequently.

To help maintain their appearance:

• Use towels when sitting
• Clean them regularly
• Avoid excessive moisture
• Do not use harsh abrasive products
• Follow the manufacturer’s maintenance recommendations

Over time, natural wood may change color. This does not necessarily mean that the wood is damaged.

How to Maintain a Wooden Sauna

Cleaning is only one part of sauna maintenance.

You should also periodically inspect:

• Wall boards
• Ceiling boards
• Benches
• Door hinges
• Door handle
• Heater
• Sauna stones
• Ventilation
• Lighting
• Electrical components

If you notice cracks, loose components, unusual odors, damaged wiring, or heater problems, address the issue before continuing regular use.

Electrical repairs should be handled by a qualified professional.

What Should You Avoid When Cleaning a Sauna?

Several common cleaning mistakes can cause unnecessary damage.

Do Not Soak the Wood

Too much water can make the drying process more difficult.

Do Not Use Harsh Chemicals

Strong cleaners may not be suitable for heated wood interiors.

Do Not Clean a Hot Heater

Always allow the sauna and heater to cool before cleaning.

Do Not Use Abrasive Scrubbers

Aggressive scrubbing can damage the surface of wooden benches and walls.

Do Not Leave Wet Towels Inside

Damp towels can contribute to unpleasant odors and unnecessary moisture.
