Should You Wipe Your Car After It Rains?

[VanAlyssa]

After being exposed to rain, it is advisable to wipe the car, and it's even better to wash it thoroughly. The reasons are explained below: 1. Overview: Washing the car is not just because it's dirty, but also to protect the paint. Rainwater can form droplets, and applying an oily protective film on the paint surface can prevent rainwater from directly corroding the paint. Conversely, if rainwater forms a film directly on the paint surface, it will not only make the car dirtier but also accelerate the erosion of the car's paint by acid rain. 2. Additional Notes: Rain contains various harmful substances. Once absorbed by dust and dirt, acid rain can easily corrode the car's paint. Moreover, the muddy water on the car's body, when exposed to sunlight, can increase the surface temperature of the car, leading to gradual corrosion of the paint surface.
