Will License Plates Rust?

License plates do not rust as they are not made of iron but rather aluminum alloy, and they are coated with anti-corrosion paint. While the plate itself won't rust, the anti-theft screws may. Here are some solutions for dealing with rust on license plates: 1. Rust stains or spots: If you notice rust spots or stains on the surface of your car, promptly visit an auto beauty shop or repair shop for touch-ups. 2. Minor rust: You can first use water sandpaper dipped in water to remove the rust spots. After completely cleaning the rust, apply primer and the original or a similar paint. It's important to note that when removing rust, you should slightly expand the area being treated. This is because some rust may be beneath the paint, and if not thoroughly removed before repainting, it will continue to corrode.

License plate rust is something I find quite common, especially with my old car that I've driven for half my life. In the past, license plates were mostly made of iron sheets, and after prolonged exposure to wind and rain, they tend to rust. The main cause of rust is exposure to rain or road salt—once the coating is damaged, oxidation begins. I had an old car parked outdoors, and its license plate became so rusty that the numbers were almost illegible. To prevent this, I now regularly clean my license plate, dry it, and apply some car wax to protect the surface. If the rust is severe, it's best to replace the plate immediately; otherwise, the police might issue a fine, and it's also unsafe. Don’t slack on regular maintenance—just a few simple steps can extend your license plate's lifespan.

License plates will definitely rust! I encountered this right after getting my driver's license—my newly purchased used car's plates had some rust. I later learned it was due to rainwater accumulation and not drying them properly after washing. Both aluminum and steel plates can't escape corrosion. The solution is quite simple: wipe the plates when washing the car and spray some rust inhibitor. If the rust gets severe and blurs the numbers, you might get pulled over by traffic police. Daily parking should avoid muddy areas, and cleaning promptly after rain or snow helps prevent rust. Some friends apply protective coatings periodically, which also works well. Don’t underestimate this—severely rusted plates can cause serious issues.

License plate rust issues stem from material and environmental factors. Typically made of metal, like the commonly used aluminum plates, they are prone to corrosion from salt and moisture in humid or coastal climates, especially when the protective coating is scratched, accelerating oxidation and causing rust spots. Prevention involves keeping them dry and clean, with professional anti-rust sprays as an option. Severely rusted plates should be replaced to avoid illegibility and potential violations. Regular checks can nip problems in the bud.
