A good sauna hat is made to become part of your regular sauna routine.
But because it sits on your head in a hot environment, it’s worth knowing how to care for it properly. The good news is that caring for a merino wool sauna hat is simple once you know the basics.
The main rule is this: keep it clean, let it dry properly, and avoid harsh washing or high heat drying.
Quick answer: how do you wash a merino wool sauna hat?
To wash a merino wool sauna hat, use cool water and a gentle wool-friendly detergent. Avoid hot water, harsh chemicals, machine washing and tumble drying. After washing, gently reshape the hat and let it air dry naturally.
You do not need to wash your sauna hat after every session. Most of the time, letting it air dry properly is enough.
Do you need to wash a sauna hat after every use?
No. In most cases, you do not need to wash your sauna hat after every sauna session.
After using your hat, let it dry fully in a well-ventilated space. This helps keep it fresh and ready for your next session.
If the hat becomes visibly dirty, starts to smell, or has had heavy use, then it may be time for a gentle clean.
How to care for your sauna hat after each session
1. Let it air dry
After your sauna session, place your hat somewhere dry and ventilated. Avoid leaving it bunched up in a gym bag, wet towel or closed container.
Good airflow is the simplest way to keep your hat feeling fresh between uses.
2. Keep it out of direct high heat
Your hat is designed for sauna use, but you still want to avoid unnecessary harsh treatment when drying it. Do not place it on a heater, in a dryer or directly under intense heat to speed up the drying process.
3. Store it somewhere dry
Once your sauna hat is dry, store it somewhere clean and dry. This helps preserve the shape and keeps it ready for your next sauna session.
How to hand wash a merino wool sauna hat
When your sauna hat needs a proper clean, hand washing is the safest option.
Step 1: Use cool water
Fill a basin or sink with cool water. Avoid hot water, as high heat can affect wool fibres and shape.
Step 2: Add a gentle wool-friendly detergent
Use a small amount of mild detergent suitable for wool. Avoid bleach, harsh stain removers or strong laundry products.
Step 3: Gently wash by hand
Place the hat in the water and gently move it around. Do not scrub aggressively, twist or wring the wool.
Step 4: Rinse carefully
Rinse with cool clean water until the detergent is removed.
Step 5: Press out excess water
Gently press the hat between your hands or inside a clean towel to remove excess water. Do not wring it out.
Step 6: Reshape and air dry
Reshape the hat while damp, then let it air dry naturally. Place it somewhere with good airflow and avoid tumble drying.

Can you put a sauna hat in the washing machine?
Hand washing is the safest option for a merino wool sauna hat.
Some wool products may allow delicate machine washing, but if you are unsure, avoid the washing machine. Machine washing can be rough on wool and may affect the shape, feel or structure of the hat.
Can you tumble dry a sauna hat?
No. Do not tumble dry a merino wool sauna hat.
High heat and tumbling can affect wool fibres and change the shape of the hat. Air drying is the better option.
How often should you wash your sauna hat?
There is no fixed rule. It depends on how often you use it and how much it needs cleaning.
For many regular sauna users, airing the hat out properly after each session and washing only when needed is enough.
You may want to wash it when:
- it starts to smell
- it becomes visibly dirty
- it has been used heavily over time
- it has been left damp in a bag
Why proper care matters
A sauna hat is a simple accessory, but proper care helps keep it feeling better for longer.
With regular airing, gentle washing and proper drying, your merino wool sauna hat can stay fresh and ready for your sauna routine.
