1. Choose your washer cycle wisely

The gentle or delicates cycle on a washing machine will come the closest to replicating hand-washing, so that’s the one you should use. (Quick lesson: Washing machine cycles are based on the speed of the wash and spin cycles. The slower the speed, the less abrasion and agitation the clothes are subjected to. In the case of your bras, slower is better because of the elastic and any embellishments on the bra benefit from dealing with less stress.)

2. Use the right detergent

Specialty detergents designed for use on bras and other delicate garments like shapewear or cashmere sweaters are a great choice whether you’re washing your bras by hand or in the washing machine. You can find delicates detergents in a range of prices, from the wallet-friendly Ecover Delicate Wash to the pricier Delicate Wash by The Laundress.

If you want something more multipurpose, opt for an eco-friendly detergent, or one of those “free and clear” options that most of the major laundry detergent brands offer (like Tide Free & Gentle or Wisk Free & Pure). Those detergents will be gentle enough for bras but effective enough for use on less delicate items of clothing.

3. Put your bras in a bag

One of the problems with machine washing bras is that the straps and hooks can easily become tangled or snagged on other garments during the wash and spin cycles. Putting bras into zip-up mesh bags will protect the straps from winding around larger items and becoming stretched out. They will also help to keep hooks from snagging materials like fine cotton. Just be sure not to overstuff the bags, which will prevent the bras from getting fully clean.

4. Wash like with like

Even if you’re diligent about putting bras in protective mesh bags, you should still avoid machine-washing delicates with heavy items like jeans, sweatshirts, or towels. Those things are likely to cause damage to elastic, and metal or plastic underwire.

5. Always air-dry — always, always, always!

Here’s where the hard-line comes in: Never put your bras in the dryer. You should always hang your bras to dry or lay them flat. If you opt to hang a bra to dry, do so by the center gore (the piece in between the cups) rather than by the straps, which will get stretched out because the wet cups will pull the garment downward. That mesh bag will come in handy for this purpose — you can just pluck it right out of the wash and set it aside before transferring the rest of the load to the dryer.

6. Rinse in the shower

Somewhere in between hand- and machine-washing lies this neat trick, which will buy you a few more wears in between washings: Shower-rinsing! It is exactly what it sounds like — take your bra into the shower with you and rinse it with water, which will help to wick away body oil and skin buildup, then hang it by the center gore to dry. Frequent rinsing will help you cut back on the frequency with which you need to launder your bra, which means it won’t be subjected to the potential damage machine-washing can cause.
