[RemingtonFitz]

To prevent rainwater on car windows, you can use a rain repellent. First, clean the dust and stains on the glass surface and wipe it dry. Spray the rain repellent evenly on the glass surface. After application, wait for 5 to 10 minutes until the glass surface is dry, then use a car cloth or tissue to wipe the glass surface until it becomes shiny.
