Does Heavy Rain Cause Damage to Cars?

[EllianaLynn]

Whether parking a car outdoors during a heavy rain is harmful depends on the location; avoid low-lying areas to prevent flooding. Regularly check the vehicle's drainage channels for blockages. Detailed explanations are as follows: 1. Paint surface may corrode: Some areas have pollution, and the rain could be acid rain, exposing the car's paint directly to acid rain, which can cause corrosion, leading to rain marks, oxidation, or even cracking. 2. Dampness and mold: Compared to sunny days, the car interior is more prone to dampness and mold after rain. Additionally, rainwater can seep through the car's seams, causing metal parts to rust and corrode. Therefore, after the rain stops, accumulated moisture should be removed as soon as possible to prevent mold. 3. Bacterial growth: Bacteria thrive in damp environments, and the more humid the area, the faster bacteria multiply, especially during the rainy season. In normal times, areas without rain can be ventilated to maintain air circulation inside the car. However, during the rainy season, avoid opening windows for ventilation, as this can lead to rapid bacterial growth inside the car.
