How to Wash Bras So They Last

Short answer: Bras are best washed at 30 degrees on a delicate cycle in a laundry bag, with the hooks fastened and no fabric softener. Let the bra air dry flat and keep it out of the tumble dryer, and both the elastic and the shape will last far longer.

Washing a bra step by step

Fasten the hooks, so they do not catch on other clothes, and put the bra in a laundry bag. Wash at 30 degrees on a delicate cycle with a mild detergent and no fabric softener, because softener leaves a film that breaks down the elastic over time. Hand washing is even gentler, if you have the time.

Drying is half the job

The tumble dryer is the biggest culprit when bras lose their shape. The heat ruins the elastic, and the tumbling motion twists the fabric out of shape. Instead, let the bra dry flat on a towel, or hang it over a washing line by the middle, not by the straps.

Especially for bamboo bras

A bamboo bra without underwire is made from soft bamboo viscose, which thrives on exactly that: a low temperature and air drying. You can read our full guide to washing and caring for bamboo clothing, and find more soft basics under bamboo underwear for women.

Frequently asked questions

How often should a bra be washed?

After two to four days of wear is a good rule of thumb. If you sweat a lot, or the weather is hot, wash more often. Rotate between several bras, so each one gets a rest between washes.

Can bras go in the tumble dryer?

No, preferably not. The heat breaks down the elastic, and the bra loses its support faster. Air drying preserves the shape best.

Can I wash bras together with other clothes?

Yes, as long as the bra is in a laundry bag with the hooks fastened, and you wash with similar colours on a delicate cycle.
