I clean them at the shower every time I use it, just a little soap and then rinse it. The removable core also gets that but then it gets dried with a towel while the strap is left hanging.

You guys make me feel the dirtiest gymgoer ever.

I was woried the wires inside the stripe might break if put into the washing machine. Maybe inside one of those porous bags… I think I’ll just do what @ryo@lemmy.eco.br does. Thanks.

The battery/circuitry pack is removable on mine. Can toss the strap into the washer on gentle or hand wash in the sink with some dish soap or laundry detergent. Air dry and done.
