How should I clean and maintain the Amazfit GTS 3?

Avoid using detergents such as soap, hand sanitizer, bath foam, or lotion, as these can irritate the skin, corrode the device, or degrade water resistance. After wearing the device while bathing, swimming, or sweating, promptly clean and dry the device. Do not place the device in direct sunlight for long periods, and keep it dry and away from humidity during transportation. (Page 20)
