What are the effects of seawater on cars?

[DeAlice]

Washing a car with seawater can cause damage, as it can corrode the car's paint and metal components. Here are some car washing precautions: 1. Avoid using excessively high water pressure: At professional car washes, the water gun is carefully calibrated. Generally, the water pressure should be between 4-7Mpa. If the pressure is too low, it won't clean effectively, and if it's too high, the water flow carrying dirt particles may impact the paint layer, causing damage to the car's paint. 2. Avoid washing the car under direct sunlight: After rinsing the car body, water droplets can act as convex lenses, focusing sunlight on the car's surface. Over time, this can cause the paint to lose its luster. The same applies to waxing—try to do it on cloudy days or indoors.
