Reminder:

1. You can wash the mug the usual way, but refrain from washing the battery compartment or using dishwasher to avoid causing damage.
2.  Wash the mug after use.
3. If the mug is not washed immediately after use, the leftover from drink such as sugar may deposit at the bottom of the mug causing stirrer unable to spin. To solve this issue, just pour hot water into the mug to soak it, then use chopstick or spoon to press and stir the white silicone at the bottom of the mug. After that, the self-stirring mug is back to functioning smoothly again!
