I'll wring the dead skin out of your accessory, just book a time.

But seriously though if dead skin is coming out then you're doing a good job manually. Putting things in a washing machine is equivalent to putting them in a bucket and spinning the bucket back and forth a few times anyway, it isn't magical.

For my normal track straps I used to put them in on a delicate cycle though. The battery ones are cursed though and I have no option but manual washing. Luckily I wear them on top of other clothing like socks so they don't get so dirty anyway.
