Can my Japanese cast iron teapot rust?

It is possible that a Japanese cast iron teapot will show rust. This is ok. The teapot can be used normally. If you still want to remove the rust, you can do that by brushing the rust with a soft brush. Then fill the pot with boiling water and add loose tea leaves. Then let it stand for about 20 minutes. Take out the tea and rinse the pot with warm water. Because the tannic acid in the tea reacts to the rust, the rust is naturally sealed and the development of new rust is prevented.
