Which Detergent Should You Use for Bamboo?

Short answer: Use a mild liquid detergent without bleach and without optical brighteners. A good detergent for bamboo can simply be an ordinary colour detergent or a wool detergent. Avoid powder with bleach, and skip fabric softener, which wears on the fibres and blocks breathability.

Why the detergent matters

Bamboo viscose is a cellulose fibre with a smooth and delicate surface. Bleach and strong enzymes can attack that surface, so the fabric loses softness and strength over time. A mild product cleans well at 30 to 40 degrees, because bamboo releases dirt and sweat more easily than cotton.

Liquid rather than powder

Choose liquid detergent over powder. Powder dissolves less well at low temperatures and can leave white residue in the fabric, especially in dark colours. Liquid detergent spreads evenly in the water from the start and rinses out more easily, which is an advantage for clothes worn close to the skin.

Colour detergent for most things

Colour detergent contains no bleach, which makes it the safe choice for coloured and dark bamboo clothing. That applies to everyday bamboo underwear for men and bamboo underwear for women, where colours last longer when they are not exposed to bleaching agents wash after wash.

White clothes need some thought

Only for pure white clothes can a white detergent be used, and then in moderation. White detergents often contain bleach and optical brighteners that are harder on the fibres. Use a mild product for everyday washing, and only use white detergent now and then if whites start to look grey.

Wool detergent for delicate items

Wool detergent is mild and free of the enzymes that break down proteins, which makes it gentle on bamboo. It suits delicate items and thin fabric well. Keep in mind that wool detergent cleans a little less strongly, so for socks and sportswear a mild colour detergent may be the better choice.

Socks and bedding

Socks absorb a lot of sweat and benefit from a mild product that cleans thoroughly without wear. Wash bamboo socks for women inside out at 40 degrees. Large items such as bamboo bedding need room in the drum, so the detergent can reach all of the fabric and rinse out properly.

What to avoid

Avoid chlorine and bleach, fabric softener and overdosing. Fabric softener coats the fibres and reduces moisture transport, and bleach weakens the fibres. Too much detergent stays in the fabric and can make it stiff. Follow the dosage on the pack, and use the lowest dose for lightly soiled clothes.

Fragrance and sensitive skin

If you have sensitive skin, a fragrance free detergent can be a good choice. Fragrance does not make clothes cleaner, and the residue sits against your skin all day. If you notice irritation, it can have many causes, so talk to your doctor if it does not settle on its own.

Temperature and programme

A mild detergent works best together with a low temperature and a gentle programme. 30 to 40 degrees on a delicate or normal cycle with a low spin is enough for most bamboo clothing. Turn clothes inside out to protect the surface, and take them out soon after the wash.

In short

The best detergent for bamboo is not a special product but a mild liquid detergent without bleach. An ordinary colour detergent or a wool detergent does the job well. Skip fabric softener, dose with care and let the clothes air dry, and they will stay soft for a long time. See also complete washing guide for bamboo clothing.
