What are the yellow dots on the car?
2 Answers
The yellow dots on the car are caused by metal dust adhering to the body and rusting over time. Methods to remove and prevent yellow dots: For small localized areas, use a damp towel to scrub firmly; if the damp towel doesn't work, purchase a cleaning wax, apply it to the towel, and gently wipe to remove the dots. When yellow dots appear in large areas, visit a car detailing shop for polishing and waxing to eliminate them. Regularly washing the car to remove dust, iron particles, and other debris from the paint surface can help protect the paint from corrosion to some extent. Reduce exposure to direct sunlight by parking indoors; if parking outdoors is unavoidable, install a car cover or canopy to shield the vehicle.
I've been driving for over 20 years and often noticed a small yellow dot on the sidewall of tires. At first, I didn't understand what it was, but later a mechanic explained that it's called the balance point, marking the lightest spot on the tire. Every time new tires are installed, they align this yellow dot with another red dot on the wheel rim to ensure even weight distribution and prevent steering wheel or front-end vibrations while driving. If they're not aligned, it can cause bumps and noise at high speeds and accelerate tire wear—I learned this the hard way. Once before a long trip, I forgot to remind the mechanic, and the car shook so badly that I had to pull over midway to check. Now, I always emphasize this point during tire changes—safety comes first. These small details might seem minor, but they can save fuel and extend tire life. I recommend new car owners pay attention to this alignment requirement during maintenance to improve driving comfort and avoid unnecessary repair costs.
