How to wash innerwear so it actually lasts

A good bra can last a year or more of regular wear. Most do not, and the reason is almost always the wash rather than the wearing.

Innerwear is mostly elastane, and elastane has three enemies: heat, harsh detergent, and mechanical stress. Avoid those and everything else takes care of itself.

Hand washing, the short version

1. Fill a basin with cool water — never hot. Heat is what breaks elastane down.
2. Add a small amount of mild detergent. Skip anything with bleach or brighteners.
3. Soak for ten minutes. Longer does not clean better and does weaken elastic.
4. Squeeze gently through the fabric. Do not scrub the cups.
5. Rinse in clean, cool water until the water runs clear.

The wringing mistake

Wringing is the single most damaging thing you can do to a bra. It twists the elastic fibres past their recovery point and misshapes moulded cups permanently.

Instead: press the water out between your palms, then lay the piece flat on a towel, roll the towel up, and press. It removes most of the water without twisting anything.

If you must use a machine

Sometimes hand washing is not realistic. If you are machine washing:

• Use a lingerie bag — without one, hooks catch on everything
• Fasten every hook first, so it cannot snag other garments
• Cold water, gentle or delicates cycle
• Never with jeans, towels or anything with a zip

Drying: shade, not sun

Direct sunlight fades colour and degrades elastic. A tumble dryer does both, faster.

Dry flat or on a line in the shade. Hang bras by the centre gore or lay them flat — hanging by one strap stretches that strap out over time, and a stretched strap will never sit right again.

Storing without crushing

Moulded cups hold their shape until something crushes them. Stack bras front to back in a drawer, cups nested the same way round. Do not fold one cup into the other — the fold becomes permanent.

Rotate, and give things a rest

Elastic needs a day to recover its shape. Wearing the same bra two days running shortens its life noticeably.

Three or four in rotation, worn in turn, will outlast two worn constantly — by more than the maths suggests.

A realistic replacement schedule

Even with perfect care, everyday bras need replacing every six to twelve months. When the band no longer feels firm on the tightest hook, the elastic has gone, and no amount of adjustment will bring it back.
