How to Wash Bras by Hand in the Sink
You should hand wash your bras in cold water (not hot!) with detergent specifically meant to be used on delicates. Taking the extra time to gently care for your bras keeps them in better condition for longer, and hand washing them is the perfect example. Hand washing is 100 percent the preferred method of washing your bras.
Can You Wash Your Bras in the Washing Machine?
Yes you can, but only if hand washing is not an option. If you wash in the machine, make sure your bras are separate from the rest of the laundry load in a lingerie bag. This will keep them from getting tangled, as will the "delicate cycle" setting, so be sure to check those boxes before just throwing your bras in the machine and starting it up.
