Is Rust in the Trunk Normal?

Rust in the trunk is a normal occurrence. Here are some precautions to avoid rust: Car chassis: The car chassis is very low and is subjected to sand and stone splashes during driving, uneven road surfaces scraping the bottom, and corrosion from rain and snow, which greatly shortens its service life. It is recommended to not only dry the chassis after washing the car but also to apply anti-rust treatment to the car chassis. Trunk: The car trunk contains items such as spare tires, luggage, and bottled water. During the rainy summer season, the temperature difference between the inside and outside can accumulate a lot of moisture, which can corrode the trunk over time. Car owners should regularly inspect the trunk, frequently air out the trunk carpet, and can also place some desiccants in the trunk to keep it dry. Braking system: After rain or car washing, a large amount of water vapor and moisture can accumulate in the brake fluid reservoir and is easily absorbed by the car's brake fluid. Some brake fluids absorb water severely, causing water droplets to vaporize at high temperatures during braking, leading to brake failure or even complete loss of braking. If it is found that the car's brake fluid has absorbed a significant amount of water, it is advisable to immediately go to a professional repair shop to remove the water.
Finding rust in the trunk of a car isn't a common occurrence and usually indicates some underlying issues that have gone unnoticed. The trunk is designed to be dry and sealed, so if rust appears, it's often due to water leakage, aging seals, or accumulated moisture from previous damage. Rust causes metal corrosion, which can compromise the structural integrity of the vehicle over time. Having inspected many cars, I've found that clogged drainage holes or water accumulation in the spare tire well are the most common culprits. I recommend you promptly inspect the rusted area, clean it thoroughly, and apply anti-rust paint to prevent further spread. If the rust is severe, it's best to seek professional repair. Regular maintenance should include keeping the trunk clean and ensuring no moisture lingers—this can save a lot of trouble. Safety comes first, so don't wait until it worsens to take action.
