1. Pour out the remaining water first, disassemble the water bottle, lid, bottle mouth and other parts, and rinse them with clear water respectively. Use a small brush to rotate the direct brush and carefully clean every corner inside the bottle. If it is a transparent bottle, the water on the inner wall of the bottle will neither condense into water droplets nor flow downwards in strands, that is, it will be washed clean.

2. The spout is in direct contact with oral contaminated saliva, and the spout exposed during outdoor sports will also be polluted by dust. In addition, a large number of sugary drinks will remain in the spout, which will breed bacteria. As the saying goes, you should pay special attention to cleaning when you get sick from your mouth. Cleaning the detachable spout is relatively simple. Pull out the spout forcibly and rinse it with clear water. If there is a sealing ring at the bottom of the spout, it needs to be removed before cleaning (if it is not removed, the back of the sealing ring will become a dead corner of fouling). If it is a non-detachable spout, you can pour a certain amount of tableware detergent into the bottle, pour water and shake it evenly, open the spout and squeeze it repeatedly for washing.

3. Threads on the spout and lid are also easy to be neglected during cleaning. It is recommended to apply a proper amount of toothpaste, scrub it repeatedly with a toothbrush, and finally rinse it off and put it in a ventilated place to dry.
