Yes! The laundry makes more sense to us, but if you want to put them in with your dishes, we're not going to stop you. Both yield similar results. You may have seen our advertisements suggesting that you are disgusting if you don't change your watch band at least as often often as your underwear - once a month. While, we say this tongue-in-cheek, watch bands can harbor bacteria just like other sweaty clothing. We recommend treating your silicone and canvas watch bands just like any other part of your wardrobe. Change them depending on the activity or outfit and put them in the wash periodically.
