How to clean a sauna. Gently.
A sauna does not need to smell like a bottle of cleaner. It needs clean surfaces and time to dry. Start with a cool room, a soft brush and the care instructions for the wood you actually have.
Which surface are you looking at?
Cool room. Gentle wash. Proper drying.
Take out loose items and remove dust before washing. Use a product approved for your sauna surfaces, brush wooden surfaces along the grain, rinse as directed and let everything dry. Keep heater work separate and follow the heater's own manual.
01 / Before you start
Wood deserves a softer approach.
Choose the method before you choose the strength of the cleaner.
Know the finish
Find the bench or sauna manufacturer's instructions. Untreated wood, treated benches and other finishes can have different care needs. Cleaning and applying a protective treatment are separate jobs.
Keep the kit gentle
Use a soft brush, clean cloths and a cleaner suitable for sauna wood. Follow its dilution and rinse instructions. Keep chlorine cleaners out of the sauna and do not mix cleaning products.
Plan the drying
Leave time for rinsing, wiping and drying before the next sauna session. Use the drying and ventilation arrangements described for your sauna, rather than leaving wet timber to look after itself.
Which surface are you looking at?
A quick reminder for the next part of the room. The full wash sequence is below.
A soft brush and suitable sauna cleaner
Check the bench finish. Work along the grain, rinse as directed and let the wood dry before use.
Chlorine cleaners, hard scouring and applying a treatment over damp wood.
02 / The steps
The wash, in a sensible order.
You are caring for timber and surfaces, not trying to scrub a new sauna out of an old one.
Let it cool, then clear the room
Clean when the sauna and heater are cool. Remove seat covers, buckets and other loose items. Take dust and loose debris off the benches and floor before adding water, and gently dust accessible wall surfaces. Follow the heater manual's shutdown instructions before working near it.

Wash the benches along the grain
Use the wood-care instructions and the cleaning product's dose. Work with a soft brush along the grain, including reachable bench edges and undersides. Apply only the water the material instructions allow. Rinse as directed and wipe away leftover water instead of flooding the room.
Skip chlorine cleaners, harsh scouring and a pressure washer on sauna wood.

Give walls and fittings their own method
Check wall-panel care instructions before wet cleaning. Clean a wooden handle as wood, and a glass door as glass. Keep cleaner and water away from electrical controls and lights. If a surface needs a protective treatment, do that only after suitable cleaning and drying, using a sauna-approved product for that surface.

Finish on the floor
Choose a cleaner that suits the floor material and clean the reachable floor last. Remove any wash water and follow the product's rinse instructions. If the drain needs attention, use the separate floor-drain guide and the fitting's own instructions. A slow drain belongs to building maintenance if ordinary cleaning does not restore the flow.

Dry before the next session
Dry loose accessories and remove excess surface water. Follow your sauna's ventilation and heater instructions for the drying stage. Harvia gives specific drying advice for its saunas, including differences in cold weather; check the arrangements for your own installation. Put textiles back only once the surfaces are dry.

03 / The finishing touch
The last step is drying.
A washed bench that stays damp is an unfinished job. Leave the room ready to dry using its intended ventilation and heater arrangements. Let that stage finish before laying out fresh seat covers.
- Wood feels dry before textiles go back.
- Loose accessories are clean and dry.
- A strange smell, damaged wood or a heater fault gets proper advice.
04 / Questions
Questions
How often should I wash the sauna?
Let usage and the manufacturer's guidance set the pace. Harvia suggests one to three basic cleans a year for a family sauna; Martat suggests a more thorough clean once or twice a year. A heavily used shared sauna needs its own maintenance plan. Remove everyday debris and keep surfaces dry between washes.

Can I use bleach in the sauna?
Martat advises avoiding chlorine-containing cleaners on sauna wood because absorbed chlorine can be released when the sauna heats up. Use a suitable sauna cleaner according to its instructions.
Guidance from: Martat (opens in a new tab)
Should I oil the benches after every wash?
Not automatically. Cleaning and surface protection are separate tasks. Check the bench manufacturer and the treatment product for suitability, timing and drying requirements. Harvia recommends sauna-specific treatment products and a test on a hidden area where appropriate.

Does this guide cover washing the heater?
It covers the room's surfaces. Heater cleaning, stone handling and maintenance depend on the model. Read the heater manual and use qualified help for electrical work. Do not pour cleaning water into the heater.
