What Is the Main Cause of Rust on Your Car?

Rust is a common problem for car owners, but what actually causes it? While it may seem like an inevitable part of vehicle aging, understanding what leads to rust formation can help you prevent it and extend the life of your car.

The Science Behind Rust

Rust, or iron oxide, occurs when metal reacts with oxygen and moisture. This process is called oxidation, and it weakens the metal, causing it to corrode over time. Since most cars are made with steel, they are highly susceptible to rusting when exposed to the right conditions.
