What are the effects of leaving a car outside in the rain?

Leaving a car outside in the rain can lead to corrosion of the paint surface, moisture and mold growth, and the breeding of bacteria. Corrosion of the paint surface: Pollution is widespread in the country, and some areas are heavily polluted. The rain that falls is mostly acid rain. Therefore, rain exposes the car's paint to acid rain, which can corrode the paint, causing rain marks, oxidation, and even cracking. Moisture and mold growth: Compared to sunny days, the interior of the car is more prone to moisture and mold growth after rain. At the same time, rainwater can seep into the car's body seams, causing iron parts to rust and corrode. Therefore, after the rain stops, accumulated moisture should be removed as soon as possible to prevent mold growth. Breeding of bacteria: It is well known that bacteria thrive in damp environments. The more humid the place, the faster bacteria multiply, especially during the rainy season. On regular days, 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 cause bacteria inside the car to multiply rapidly.
As an experienced driver with eight years behind the wheel, I believe prolonged exposure to rain can cause multiple issues for vehicles. Rainwater often carries dust and pollutants, which over time can make the car paint appear dull and lose its shine. White cars are particularly prone to developing yellow water stains. The rubber seals around the roof and door gaps, when repeatedly soaked by rainwater, tend to crack and age, leading to water leakage into the cabin during rain. The most annoying issue is the interior humidity - leather seats may develop mold spots, and the soundproofing material beneath the carpets breeds mold when dampened, resulting in a musty smell when opening car doors in summer. The chassis is also susceptible to rust when exposed to acid rain, especially around the exhaust pipe area. I recommend washing your car at least every two weeks during rainy seasons and parking in underground garages whenever possible.
