What Causes White Spots on Chrome Plating?
2 Answers
White spots on chrome plating may be caused by corrosion from car wash shops, with most cases resulting from the use of spray agents. Specific details are as follows: 1. Harsh Vehicle Environment: Additionally, white spots can occur due to a poor vehicle environment, where the chrome plating is exposed to acid rain, acid fog, or high salt content in coastal air. Since the chrome plating layer has already eroded at the white spots, they cannot be repaired. 2. Treatment Methods: The first option is polishing, but this removes the chrome layer, making it impossible to restore the original appearance and leaving the surface more susceptible to future corrosion. The second option is to seek replacement from the manufacturer, as the appearance of white spots may indicate the manufacturer's responsibility due to cost-cutting during production, resulting in poor chrome plating quality.
When I noticed white spots on the chrome parts of my car, I first observed the surrounding environment: I live in a coastal city where the air has high salt content, and during the rainy season, the humidity is high. Moisture seeps into the gaps of the chrome plating, causing oxidation that leads to white spots on the surface. This corrosion process is quite common, often seen on exposed areas like bumpers or emblems. I discussed it with a friend, who mentioned that the quality of the chrome plating also plays a role, as inferior chrome is more prone to damage. In daily life, I avoid parking under trees to prevent acid erosion from bird droppings and only use mild soapy water with a soft cloth for cleaning. White spots aren't just unsightly—they can spread and affect the car body. I found that minor spots can be removed with professional chrome cleaner, while severe cases require a trip to the auto repair shop for re-plating, costing a few hundred bucks. Regular maintenance is key, so I check monthly—prevention is better than cure.
