Does a Damp Underground Parking Space Affect the Car?
2 Answers
Damp underground parking spaces can affect the car in several ways, including increased rusting of metal parts, difficulty in drying out the air conditioning, and shortened lifespan of vehicle fluids. Here are the specific details: 1. Metal is prone to rust: In humid environments, metal undergoes oxidation reactions and is very susceptible to rust. High humidity makes car metal parts more prone to rust, especially in areas where surface rust prevention is inadequate. Solution: Taking protective measures can help avoid rust to some extent. 2. Air conditioning is harder to dry: In summer, turning on the air conditioning and driving directly into an underground parking space can make it difficult for the cold air to dry. Additionally, the air conditioning ventilation system, if kept in a moist state for a long time, can easily breed mold and produce odors. Not cleaning the air conditioning system regularly can lead to various issues and may also affect health. Solution: Regular cleaning of the air conditioning system is sufficient. 3. Shortened lifespan of vehicle fluids: High humidity can also shorten the lifespan of vehicle fluids, such as lubricating oil and brake fluid. High humidity can also increase the water content in fuel, making it harder to start the car in the morning, especially in autumn. Solution: Keep a reliable car cover and use it after parking.
I usually park my car in the underground garage, which is always damp. Leaving the car there for too long can really cause problems. The body and chassis are prone to rust—my previous car had severe rust on the chassis, costing hundreds to repair. Electronic components are also affected; for example, the headlight connectors can get moldy, causing the lights to flicker at night, which is quite dangerous. The interior is even worse—seats and carpets can become damp and moldy, producing a strange smell that gets worse when the AC is on. Additionally, the edges of the tires can rust, and wet brake pads may squeak, affecting braking performance. To avoid these issues, I use moisture absorbers, wash the car regularly, and clean the drainage holes. Parking long-term in such conditions can shorten the car's lifespan, so I recommend choosing a dry parking spot or applying anti-rust treatments.
