The reason why the front wheel of Hyundai Elantra 10 rusted was because it was in a humid environment. Because in 10, once the front wheel hub of Hyundai Elantra was flooded or driven in a humid and salty environment for a long time, the wheel hub was scratched, and a strong acid and alkali cleaner was used when washing the car, resulting in oxidative corrosion. You can wipe it with Tiger Head brand synthetic lubricating oil in a rusty place, soak it for about half an hour, and then wipe it.
