What Causes White Oxidation Spots on Wheel Hubs?

[JuneRose]

The causes of white oxidation spots on wheel hubs are: 1. The wheel hub surface is scratched by hard objects, allowing air to directly contact the aluminum and oxidize first at the damaged area, which then gradually spreads to surrounding areas during subsequent use; 2. The wheel hub oxidation is caused by corrosion from chemical products. The maintenance methods for wheel hubs are: 1. When the vehicle is located in a humid area, the wheel hubs should be cleaned frequently to prevent salt from corroding the aluminum surface; 2. If necessary, after thorough cleaning, the wheel hubs can be waxed to maintain their shine; 3. When the wheel hubs are at a high temperature, they should be allowed to cool naturally before cleaning. Do not use cold water for cleaning, as it can damage the aluminum wheel hubs, cause brake disc deformation affecting braking performance, and using cleaning agents on the wheel hubs can trigger chemical reactions on the surface, leading to loss of shine.
