Cleaning It Incorrectly
You should be cleaning your Apple Watch regularly, particularly if you wear it during sweaty or high-intensity workouts. With that being said, there’s definitely a right and a wrong way to clean your Apple Watch. And if you clean it incorrectly, you may end up damaging it.
For one, you should never use any soap, shampoo or another cleaner on your Apple Watch. (That also means you shouldn’t shower with it.) Instead, just use warm water to thoroughly clean the case and band and wipe it off with a microfiber cloth. Also, be sure to keep leather bands and accessories from getting wet.
