Causes of Oxidation:
Brake dust contains iron particles that trigger electrochemical reactions when exposed to water.
Road salt (used for melting snow in winter) adheres to the wheel surface.
Prolonged contact between acidic rainwater and the wheel coating.
Low-quality tire dressings containing petroleum solvents that dissolve the protective layer.
Daily Prevention Strategy:
Clean wheels at least once a week to prevent long-term buildup of grime.
Pay special attention to the back of the wheel during rinsing, as this is where brake dust accumulates most heavily.
Promptly wash the undercarriage and wheels after driving in winter conditions to remove salt.
Apply a wheel coating or sealant after cleaning to create a protective barrier.
Repairing Minor Oxidation:
Use a wheel polish with a foam pad at low speed to restore surface luster. Professional refurbishment is recommended for severe oxidation or scratches.
Recommendation: Choose an acid-free (water-based) tire dressing to prevent solvents from damaging the wheel rims. Regularly inspect wheels for cracks or deformation; these issues not only affect appearance but also compromise safety during high-speed driving.
