How to remove tea stains from cups

Over time, tea stains will form on tea cups, which people often call tea mountains or tea rusts. It may not be easy to see on dark-colored cups, but it is different on light-colored cups. It still feels a bit unhygienic, so it is necessary to clean it in time. This kind of thing is sometimes difficult to clean. Some people use plastic balls to clean it, and the effect is okay, but it still feels not ideal. Here are some simple and clean methods.
