How to clean the scale on the Xiaomi Multifunctional Hot Pot Cooker 6L?

After using the Xiaomi Multifunctional Hot Pot Cooker 6L for a certain period of time, scale will be deposited on the inner surface of the bottom of the pot. The amount of scale depends on the hardness of the water in the area. Regularly removing scale can prevent the heating capacity from decreasing, thereby extending the service life of the device.
Please refer to the following steps to clean the scale:
1. Add water reaching the lowest water level and add 30mL white vinegar;
Note:
Do not use other chemicals and descaling agents.
2. Place the hot pot cooker or pot lid on the base to avoid slight splashing of water;
3. Plug in the power supply and set the time to about 5 minutes in the DIY mode. After the time is up, you can unplug the plug and pour out the white vinegar after it has completely cooled down;
4. Wipe the surface of the pot with a damp cotton cloth and rinse the pot repeatedly with clean water to remove the vinegar smell;
