Does snow melt corrode the chassis of a car?

The principle of snow melting agent is not complicated. Chemically speaking, it is some salt substances, such as the common edible salt in our kitchen. It can reduce the freezing point of water, and ice water will be mixed at zero degrees Celsius. The freezing point drops to about 20 degrees Celsius. Although common snow melt is made of the same sodium chloride as the salt found at home, the salt in snow melt is not pure. In addition to sodium chloride, there is calcium chloride or magnesium chloride, so snow melt should not be used.

Is snowmelt harmful? The answer is yes, snowmelt is bad.

Snow melt can corrode the undercarriage of cars because it contains salt, which conducts electricity when dissolved in water. The metal used in car chassis is usually alloy. Normally, they have some resistance to corrosion. However, the galvanic effect occurs when the vehicle chassis is exposed to salty snow water, which does accelerate the corrosion and rust of the vehicle chassis. Therefore, when the weather is fine, should pay attention to the car wash. In addition, snowmelt can accelerate road aging. Now the roads are mainly asphalt or cement. When salt water penetrates, the internal structure will accelerate the aging, resulting in reduced road service life. Can snowmelt really harm your eyes? In theory it is possible, but in reality it is unlikely because only major city streets and Bridges would use snow melt, and it would be difficult for humans to play and play on motorways.

However, snow melting agent is a chemical raw material we live in this big world, after all, safety is the first, road safety can not be ignored.
