Is it serious if a car chassis gets exposed to seawater?
1 Answers
From a chemical perspective, seawater is an electrolyte, and most components of a car chassis and other parts are made of alloys. This usually leads to galvanic redox reactions, accelerating metal corrosion, which is harmful to the car. It is recommended to clean the chassis and take protective measures, such as painting. Below are some car washing precautions: 1. Avoid using high water pressure when washing the car: In professional car washes, the water gun is carefully selected. The water pressure should generally 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 paint surface particles may impact the paint layer, causing damage. 2. Do not wash the car under direct sunlight: After rinsing the car body, water droplets on the surface can act as convex lenses, focusing sunlight on the car body, which over time can cause the paint to lose its luster. The same applies to waxing; it's best done on cloudy days or indoors.
