Nowadays, in the upright summer, the amount of water we drink will also increase. Whether it's drinking tea, coffee, or directly drinking water, it can actually meet our drinking needs. However, drinking tea naturally requires the use of a cup. Whenever I finish drinking tea myself with a glass or ceramic cup, if I forget to clean it and try to clean it the next day, I will find that the stains remaining on the water cup are difficult to clean. If I don't use a cup brush and just rinse it with water, it will be difficult to clean it completely. The advantages of this cup specific brush are very obvious. Its bristles are long and tight, which can easily reach the bottom of the cup and some places that are difficult for us to reach, allowing us to quickly complete the cleaning work of the cup, which is very convenient.
