Can I add pure water to the car glass water, Zhihu?

Car glass water can be added with purified water, but it can't be used for a long time and can only be replaced temporarily. Harm of adding purified water to automobile glass water for a long time: 1. Mineral water is not lubricated. If you use it for a long time, you will find that the windshield of the car is badly scratched, and the friction between the wiper and the glass will increase when you use it. Jumping and abnormal sound will occur; 2. Mineral water originally contains other components, which will precipitate more or less, leading to pipeline blockage, which may affect the service life of the water storage tank; 3. In winter or cold regions, due to the lack of anti-freezing function of glass water, mineral water condenses into ice, and its volume will increase accordingly (involving physics and chemistry), resulting in frost cracking of the water storage tank. If the glass water switch is used continuously, the automobile compressor will be easily damaged.
