Why Do Car Wheels Rust?

[McBentley]

When a car is exposed to humid environments for extended periods, the wheel hub surface may suffer scratches or other damages, and the use of cleaning agents containing acids or alkalis can lead to corrosion and rust on the wheel hub. Below are some relevant explanations: 1. Rust Spots: If the rust is not severe, you can first use very fine water sandpaper dipped in water to gently sand away the rust spots, then thoroughly clean the area and apply a layer of primer. This will ensure the rust does not spread or worsen. For new scratches, you can clean the area and directly apply primer. Most vehicles come with a small can of original paint. Although this treatment may not look very appealing, it is acceptable for very small areas. 2. Wheel Hub Repair: If there are scratches on the wheel hub surface but no rust has appeared yet, it is advisable to perform wheel hub repair. This helps prevent the wheel hub from rusting or corroding when exposed to cleaning agents.
