Underwire bras and washing machines

The wires can come out and make nasty noises in your washing machine until someone spends a few hours taking it apart to get the wire out. Even out of the new ones that aren't fraying at all. You can avoid this by putting them in a bag or pillowcase (or handwashing, obviously).
This has been a public service announcement on behalf of people who just spent a few hours getting a wire out of a washing machine and putting the machine back together. Thank you.
