Is Washing the Car at Noon Harmful to the Paint?

[DelAna]

Washing the car at noon can damage the paint. After being exposed to the midday sun, the car's paint surface becomes very hot. When cold water comes into contact with the hot paint surface, the temperature difference can make the paint brittle and prone to cracking. Precautions for car washing: 1. Avoid using hard water: Do not use anything other than soft water for washing, including hot water, alkaline water, or water with high hardness. These substances can damage the paint. Washing with hard water can leave marks and a film on the car's surface after drying. 2. Avoid using high-pressure water streams: Excessive water pressure can harm the car's paint. If there is stubborn dirt or mud on the car, soak it with water first before rinsing. Use a dispersed water stream for spraying.
