Is the Humidity in Underground Garages Harmful to Cars?
2 Answers
Underground garage humidity has significant impacts on vehicles. Here is relevant information about the effects of underground garage humidity on cars: 1. Electrical components: The onboard computer, CD, DVD, and car audio systems are most susceptible to moisture. Many CDs and DVDs may fail to read discs or get stuck in the player, often due to humidity. 2. Body: The car body, made of sheet metal, is prone to corrosion when exposed to humid air. The braking system can also suffer severe rusting, and electronic components may be affected. The high concentration of moisture in humid air can corrode the car's paint, reducing its gloss and even causing rust in areas with minor scratches. This damage can be more severe than exposure to intense sunlight.
When it comes to damp underground garages, my old buddies and I—who've been driving for over a decade—have plenty to say. Last time my old Ford Focus sat in the community garage for six months, rust spots popped up on the chassis. The mechanic said the humid air made the metal feel like it was soaking in saltwater. The most annoying part was the electronics—after the rainy season, the infotainment screen would occasionally glitch, and repairs weren’t cheap. Then there’s the musty smell, with black spots growing in the seat seams that won’t wash out. I’ve learned my lesson now—I tossed a few moisture absorbers in the trunk and take the car out for a spin every two weeks, letting the A/C blow through the floor mats. If you ask me, long-term garage parking calls for regular checks on brake discs and wiring connectors.
