Do I absolutely have to hand wash bras?

When I was washing bras by myself, I used to just gently hand-wash them in the shower and that was it~

But now that both of my teenage daughters have started wearing bras, there's just so much hand laundry to do...

These days, it's so hot that people sometimes take off two bras at a time just because they're soaked in sweat, so I have to wash so many bras a day...

Now that I'm at the age where my wrists are starting to hurt, I really don't want to do laundry by hand, but my lazy daughters keep making me work, telling me to grow old.

Ugh, I guess I'll have to make him wash it himself now.

Or maybe I should just run the washing machine.
