If you use tap water, the inner pot will develop spots of limescale, which is normal. Use a scouring pad to gently remove the limescale from the inner pot.
You can refer to the following methods to remove severe limescale in the Xiaomi Multifunctional Hot Pot Cooker 6L:
1. You can use the white vinegar to remove the limescale. Pour an appropriate amount of white vinegar into the hot pot cooker, let stand for 1 hour without heating, pour out the white vinegar, and clean the hot pot cooker with clean water for 5 to 6 times. If the limescale remains, repeat the preceding steps;
2. Additionally, you can use the citric acid to remove the limescale. Pour an appropriate amount of water into the hot pot cooker, boil it using the hot pot mode, and then turn off the heat. Add 25g of citric acid, let stand for 15 minutes, and pour out the citric acid water. Then, clean the hot pot cooker with clean water for 5 to 6 times.
