How to care for my sauna

1. Daily care after use

After each sauna session, wipe down benches, backrests, and walls with a soft towel while the sauna is still warm. This removes sweat and moisture before it absorbs into the timber.

Use plain warm water or a natural mix of three parts water and one part vinegar. Avoid soaking the wood. A light wipe is all that is required.

Leave the sauna door open for 15 to 20 minutes after use to allow proper ventilation and drying.

2. Using towels

Always sit on a towel during sauna sessions and place towels under your feet where possible. Towels absorb sweat and protect the timber from moisture, staining, and odour.

This simple habit significantly extends the life of your sauna.

3. Weekly cleaning

Every five to seven uses, clean all internal timber surfaces using a water and vinegar mix or water with a small amount of mild soap.

Use a soft cloth or non abrasive sponge. Gently clean any marks in small circular motions. Do not use bleach, harsh chemicals, or abrasive pads.

4. Monthly maintenance

Once a month, vacuum or sweep the floor and the areas under benches. Wipe underneath benches and into corners where moisture may sit.

Clean door handles and control panels with a lightly damp cloth. Ensure the sauna is switched off and fully cool before cleaning heaters or panels.

5. Preventing mould

Mould is caused by trapped moisture. Always allow your sauna to dry fully after use with the door open.

If mould appears, clean early using a stronger vinegar and water mix. Tea tree oil may also be used sparingly as a natural antifungal.

6. Outdoor sauna care

For outdoor saunas, re coat the exterior timber once per year using a high quality outdoor wood oil or sealant. This protects the sauna from sun, rain, and temperature changes.

Do not treat internal timber. Interior wood must remain untreated for safe and correct performance.

7. Additional care tips

Avoid scented or chemical cleaners inside the sauna. Do not paint, varnish, or seal internal timber.

Clean glass panels only when cool using a natural vinegar and water mix. Wash sauna towels and mats regularly.
