To prevent rust on car doors, regularly wash your car, apply a protective coating, and ensure the door surfaces stay dry. Using anti-rust sprays, waxing, and parking in a dry, damp-free garage can also help reduce rust formation.

Salt, especially on roads during winter, accelerates rust formation by reacting with metal and water. Changes in temperature can also cause metal to expand and contract, leading to cracks where rust can develop. How Weather and Road Salt Cause Rust In winter, road salt mixes with snow and water, creating a salty moisture that coats your car. This can accumulate in car doors, especially near the underbody and wheel wells. During cold weather, low temperatures and dampness increase the chances of rust. Salty moisture, when not removed promptly, can eat away at the car’s metal surface, leading to rust formation over time.
