What Are the Yellow Spots on the Car?
1 Answers
They are rust spots. Yellow spots on the car's paint surface are generally caused by rusting iron particles adhering to the surface. When the car's surface generates static electricity, it attracts iron particles from the air onto the paint. If the car is exposed to rain, these iron particles on the paint surface will rust. Methods to remove rust from the car are as follows: Use a cloth soaked with bathroom cleaner and wipe the rusted area back and forth. After cleaning, make sure to wash your hands thoroughly. Use machine oil. Choose a transparent, non-sticky machine oil, apply it to a cloth, and gently wipe the rusted area. After removing the rust, use a soft, dry cloth to wipe off any residual oil on the car body. Do not rinse with water. Use acidic substances like dilute hydrochloric acid or oxalic acid for wiping. Be careful not to use too much to avoid secondary corrosion. After removing the rust, maintain the surface by waxing or polishing. Use a car paint iron particle remover, which quickly dissolves iron particles and oxidation layers on the paint. Spray the remover on the rust, and the iron particles in the paint will dissolve. After spraying, the iron particles will turn into a purple liquid and flow off. Rinse with clean water afterward. Precautions for car paint maintenance include the following: Before, during, and after using the car, promptly remove dust from the body to minimize the adsorption of dust due to static electricity. Rinse the car promptly after rain. Raindrops on the car will gradually shrink, increasing the concentration of acidic substances in the rainwater. If not rinsed with water quickly, the rain residue will damage the paint over time. When washing the car, wait for the engine to cool down. Avoid washing the car under direct sunlight or high temperatures to prevent cleaning agents from drying and leaving marks. When washing the car yourself, use specialized detergents and neutral water. Avoid using highly alkaline detergents like laundry powder, soap, or dishwashing liquid, as they can strip the paint of its protective oils and accelerate aging. Use clean, soft cloths or sponges to wipe the car to avoid mixing in metal shavings or sand particles. Do not use dry cloths, towels, or sponges, as they may leave scratches. Wipe in the direction of water flow, gently from top to bottom, avoiding circular or horizontal motions. For particularly strong corrosive stains, remove them promptly. Use specialized cleaning agents for such stains and avoid scraping with blades or using gasoline, as these can damage the paint.
