Can detergent be used as glass water?

It can be used, but it is not safe enough.

Usually, in order to clean the windshield with wiper water, many riders will directly add ordinary household detergent into the wiper water, but the ordinary household detergent is alkaline and easy to corrode the rubber strip of the wiper. The corroded rubber strip is easy to age, which makes the wiper unable to scrape the glass.

Secondly, the detergent is not as clean and thorough as glass water, and incomplete dilution will produce oxidation records and block the nozzle.

However, if you clean glass in a hotel or at home, you can use a cleaner.
