Washing Underwear – The Temperature Guide

Short answer: Washing bamboo underwear is best done at 40 degrees. That is hot enough for good hygiene on clothing worn close to the skin, and gentle enough to preserve softness and elastic. Bras and delicate items are washed at 30 degrees in a laundry bag.

The right temperature for everyday underwear

Briefs, boxer shorts and undershirts in bamboo viscose come out clean at 40 degrees with a mild detergent. Modern detergents work effectively at low temperatures, and bamboo releases sweat and dirt easily. Have a look at the range of bamboo underwear for men and bamboo underwear for women, and read more about the material in our big underwear guide.

Delicate items: bras and lace

A bamboo bra without underwire and other delicate items are best washed at 30 degrees on a gentle programme and in a laundry bag, so straps and fabric are not pulled out of shape. Close hook-and-loop fastenings and zips on the rest of the laundry before it goes into the same machine.

Three rules that keep your underwear looking good

Use a liquid detergent without bleach, skip the fabric softener, which blocks the breathability of bamboo, and air dry instead of tumble drying. Elastic and fibres last markedly longer without the heat of the dryer. You will find the whole routine in the complete washing guide for bamboo clothing, and if you need to find the right style, our briefs guide will help.
