What are the effects of a car being exposed to rain all night?

[GemmaRose]

The effects of a car being exposed to rain all night are as follows: The car paint may be corroded: In some heavily polluted areas, the rain is mostly acid rain, so exposure to rain is equivalent to exposing the car paint directly to acid rain, which can corrode the paint, leading to rain marks, oxidation, and even cracking. Moisture and mold: Compared to sunny days, the interior of the car is more prone to moisture and mold after rain. At the same time, rainwater can seep into the seams of the car body, causing iron parts to rust and corrode easily. Therefore, after the rain stops, accumulated moisture should be removed as soon as possible to prevent mold growth. Bacterial growth: The more humid the environment, the faster bacteria multiply, especially during the rainy season. Places that are usually dry can be ventilated to maintain air circulation, but during the rainy season, avoid opening windows for ventilation, as this can lead to a rapid multiplication of bacteria inside the car. Rainwater entering the headlights: Water entering the headlights can affect their brightness, and excessive water may damage the headlights. It can also alter the direction of light refraction, posing a safety hazard while driving.
