How to Wash Bras
Updated July 2026
The short answer
Check the care label, fasten the hooks, and put bras in a mesh laundry bag on a delicate cycle with cool water and a gentle detergent, or hand wash them in the sink. Either way, the drying rule is the same and it is the one that actually saves bras: air dry, never the dryer, unless the label specifically says machine drying is allowed. Dryer heat is what kills the elastic, warps underwires, and breaks down molded cups.
Before you start
- Read the care label. Machine washable is common; some lace, molded, and specialty bras are hand wash only.
- Fasten every hook. Loose hooks snag lace, mesh bags, and everything else in the load.
- Use a mesh bag for machine washing. It stops straps from tangling and cups from being crushed.
- Pick a gentle detergent. Skip fabric softener, especially on sports bras and other performance fabrics where the manufacturer advises against it, because it coats the fibers that manage stretch and sweat.
- Sort bras with similar lightweight items, not with jeans and towels.
Steps: machine washing bras
- 1Fasten hooks and bag the bras. One or two bras per mesh bag keeps shapes intact.
- 2Choose the delicate cycle with cool water. Gentle agitation and low temperature protect elastic and padding.
- 3Dose detergent lightly. Bras are small; a little gentle detergent cleans them fine and rinses out fully.
- 4Take them out as soon as the cycle ends. Gently press out extra water through a towel if needed. Never wring a molded cup; squeezing it into a twist creases the foam.
- 5Reshape while damp. Cup the padding back into form and straighten the band and straps.
- 6Air dry. Lay flat, or drape over a rod by the center panel between the cups. Hanging a wet bra by its straps stretches them.
Hand washing and special cases
Hand washing:
A few minutes in a sink of cool water with gentle detergent, soft squeezing, a thorough rinse, then the same reshape-and-air-dry finish. This is the gentlest option for lace and delicate trims.
Sports bras:
Usually the most machine-tolerant, but the most softener-sensitive. Wash after sweaty wear, cold and gentle, and air dry.
Molded and padded cups:
Never wring or fold. Reshape damp so the foam dries in its proper form.
Adhesive and specialty bras:
Follow the manufacturer's instructions exactly; most adhesive styles are hand wash only, and heat ruins the adhesive.
What not to do
- Do not machine dry bras unless the label explicitly permits it. Heat degrades elastic, foam, and adhesives faster than anything else you can do to a bra.
- Do not wash bras with hooks open.
- Do not wring or twist molded cups.
- Do not hang wet bras by the straps.
- Do not assume every bra needs hand washing; the label often approves the far easier mesh-bag route.
- Do not use fabric softener on performance fabrics against the manufacturer's advice.
What to expect
Good washing habits keep the band snug and the cups shaped for much longer, but elastic is a consumable: once a band has stretched out or a wire has distorted, washing cannot restore it. If a bra fits poorly no matter how it is washed, it is worn out or was never the right size.
Frequently asked questions
How often should bras be washed?
A common rhythm is after every few wears, sooner in hot weather or after workouts. Rotating between a few bras rests the elastic between wears.
Can bras go in the dryer on low?
Skip it unless the label says otherwise. Even low heat cycles add up on elastic, and the tumbling bends underwires against the drum.
Why does my underwire poke through after washing?
Usually wear and metal fatigue rather than one wash. Rough cycles without a mesh bag speed it up. Once a wire has escaped, repair or replacement beats re-washing strategies.
Do sports bras really need different care?
Mostly the same, with one extra rule: no fabric softener, which interferes with moisture-wicking fabric and its stretch.
