Bamboo underwear and when 60 degrees is necessary

Short answer: 60 degrees is necessary when there is illness in the household, with fungal infections and after contact with something that must be removed completely. For everyday use, the high temperature does more harm than good, because it wears out the elastic and colours.

When it is justified

With a stomach bug, a fungal skin infection or after a hospital stay, a high temperature is justified. It is a hygiene measure, not an ordinary cleaning task. If a doctor has given you specific advice on washing, follow it rather than general rules of thumb. Read more about temperatures under washing and care.

What it costs

60 degrees wears out the elastic faster and makes colours fade. A pair washed hot every week loses the stretch in its waistband sooner than a pair washed at a lower temperature. You notice it first at the waist, where the band starts to give. So use the high temperature only when there is a reason. See bamboo underpants for men.

Can bamboo viscose take it

Yes, the fabric can handle 60 degrees. The delicate part is the elastane in the waistband and fabric, not the fibre itself. Elastane gradually loses its ability to spring back when it is exposed to high heat many times. Always check the care label on each item before choosing a high temperature.

The everyday alternative

40 degrees with a proper detergent removes grease, sweat and skin cells. That is enough for normal use, even for underwear worn every day. What matters most is not the temperature, but letting the detergent work and not overloading the machine. See bamboo underwear for men.

Do not overload the machine

An overloaded machine washes worse, whatever the temperature. Clothes need to move freely in the drum so water and detergent reach every item. Fill the drum about three quarters full. That gives a better result at 40 degrees than a packed machine at 60 degrees, and the clothes wear less.

Keep it separate during illness

If someone in the household is ill, wash their clothes separately. That makes it easier to use the high temperature exactly where it is needed, without the rest of the laundry going in too. Once the illness has passed, you can go back to 40 degrees. Always follow the advice you get from health professionals.

Drying afterwards

After a hot wash, the fabric is at its most vulnerable. Hang it up instead of tumble drying, so the elastic does not get another round of heat on top of the wash. Undershirts keep their shape best when hung on a hanger or laid flat. See bamboo undershirts for men.

Fabric softener and bleach

Skip fabric softener on bamboo viscose underwear. It coats the fibres and reduces their ability to absorb moisture. Avoid bleach and chlorine too, as they weaken the fabric and the colours. A high temperature and an ordinary detergent are enough when a more thorough wash is needed.

In short

Use 60 degrees when there is a hygiene reason, such as illness in the household, a fungal infection or a hospital stay. For everyday use, 40 degrees with a good detergent is enough and spares the elastic and colours. Do not overload the machine, skip the softener and hang your underwear to dry afterwards.

Frequently asked questions

Can bamboo underwear take 60 degrees?

Yes. The fibre itself handles the temperature well. It is the elastane in the waistband that wears with repeated hot washes, so only use 60 degrees when needed.

When is 60 degrees necessary?

With illness in the household, fungal infections and after a hospital stay. If a doctor has given you specific advice, follow it rather than general rules.
