Does Snow Affect Car Paint?

Snow does affect car paint. After snowfall, the most vulnerable part of a vehicle is the paint. Snowwater contains high levels of salt and various alkaline components. If snow splashes onto the car body or chassis and is not cleaned promptly, it can cause severe corrosion to the paint, chassis, and tires. After snowfall, it's advisable to take your car to a professional automatic car wash. These facilities use large amounts of flowing clean water with neutral cleaning agents to gently rinse the car body, and specialized wheel brushes clean the sludge from the gaps in the wheel hubs. Automatic car washes are equipped with chassis cleaning devices that use powerful upward water jets to thoroughly remove any mud or water attached to the chassis surface. When washing your car, try to use lukewarm water, as water that is too cold or too hot in cold weather can damage the paint. After washing, make sure to dry the windows, otherwise, water left in the door gaps can freeze.

I remember last year after a heavy snowfall, I noticed tiny corrosion spots along the edges of my car doors while cleaning it. The mechanic later explained that snow, seemingly harmless, actually hides hidden dangers. Snow itself is slightly acidic, and when combined with pollutants from vehicle exhaust and salt from de-icing agents in urban snow accumulation, prolonged contact can corrode the clear coat of the car's paint. Especially when snow melts and refreezes into ice, the expansion in volume can widen small cracks in the paint. Once, my neighbor used warm water to clear snow from the windshield, and the drastic temperature difference caused fine cracks in the paint. It's recommended to use a soft snow brush to remove snow as soon as possible after it stops snowing, avoiding metal tools that could scratch the paint. My current habit is to apply a ceramic coating before winter, making it harder for snow to penetrate the paint pores even if it sticks.

Our friends from the Northeast convoy specifically reminded us about the details of protecting car paint after snow. Thin snow is more dangerous than thick snow—it melts faster, and the icy water containing de-icing agents can quickly penetrate the car paint. Last week, while washing the car, I noticed sticky yellow stains on the hood. The mechanic said it was residue from road snow mixed with antifreeze. It’s especially important to remind everyone to clear snow from the trunk grooves, as standing water there is most likely to corrode the metal seams. Never use the wipers to scrape ice off the windshield—the ice particles trapped in the rubber strips can leave sun streaks. In fact, snow on the roof should be cleared first, otherwise, it may slide down while driving and obstruct your view.

The dirty snow water kicked up by tires after snowfall acts like sandpaper, grinding against the car's rocker panels. I've personally seen a colleague's white SUV turn yellow from road salt, with the rocker panel paint bubbling and peeling after three months. Friends who park outdoors should opt for a thickened car cover, as regular covers become harder to remove when frozen under snow. Metal snow scrapers pose a greater paint-scratching risk than imagined, while plastic ones break easily. After learning my lesson, I now carry half a bottle of warm water to melt ice around door handles. Technician Wang from the repair shop warns that scratches on the paint require extra caution, as snowmelt seeping into the primer can cause localized rust-through.

Just saw a case of paint damage caused by snow at a car detailing shop. The owner used hot water to melt the snow, resulting in spider-web cracks on the paint surface, and the repainting cost over two thousand. Snow pressing down on fallen leaves is the worst, as the acidic substances from decaying leaves can be carried by snowmelt into the paint pores. The edges of door seals are high-risk areas, as melting snow can seep into the door cavities along the rubber strips. Snow around the rearview mirror pivot should be cleared promptly, as forcing it to move when frozen may tear the paint. My experience is to use de-icing spray to dissolve ice on windows, but be cautious with chemicals on the paint. Actually, snow near the engine hood's cooling vents should be cleared first to prevent melted snow from flowing into the engine compartment.
