The three-in-one tea maker is in use, and there is a small circle of scale on the heating plate in the pot. Is there any cleaning method?
Recommend three methods for quick scale removal at home: 1. It is laborious to put the broken egg shell into the teapot and shake it constantly. Soak in white vinegar for one night, and then pour off the scale the next day. This is easier. 3. Put a spoonful of baking soda and boil it in hot water for a few minutes to remove scales.
