What is the best water to use for washing a car?

[StGraham]

In summer, cold water can be used. In winter, when the temperature is relatively low, it is important to pay attention to the water temperature when washing the car. Using cold water may cause freezing. Below is some relevant information about car washing: Never use laundry detergent: This is the biggest taboo when washing a car. Laundry detergent is highly alkaline, and using it can accelerate the aging of the paint and tires. It is essential to use a neutral car wash solution. Rinsing sequence: When rinsing the car, there should be a specific sequence; it cannot be done haphazardly. This is especially important in winter. If the car wash solution is not rinsed off thoroughly, it can affect the car's paint. Rinsing should be done from top to bottom, following the direction of the water flow, to quickly remove the car wash solution. Avoid using a high-pressure water gun directly on the paint surface, as it can damage the car's finish.
