How to Deal with Stains on Car Paint?
2 Answers
It is particularly important to promptly address stains on car paint. If detected early, they can be wiped off directly with a cloth. However, if paint or grease stains have been present for a long time, the paint surface may develop wrinkles, bubbles, cracks, or the so-called "orange peel" effect. In such cases, simply waxing is no longer sufficient. It is necessary to use sandpaper specifically designed for car cleaning to remove the paint or grease stains, followed by waxing to restore the shine of the car surface. Below are solutions for yellowing white car paint: 1. Wash the car frequently: Most cars are parked outdoors, exposed to wind, rain, and sunlight, which can oxidize the paint. Rainwater contains a large amount of acidic substances that can be corrosive. If not cleaned in time, the car will lose its shine and yellow more quickly. White cars are more susceptible to yellowing compared to other colors, so frequent washing is essential. 2. Waxing: Another reason white cars are prone to yellowing is that the paint surface has many tiny gaps, which are difficult to see with the naked eye but can absorb dust particles from the air, accelerating paint oxidation. Therefore, the best solution is to apply wax, which forms a protective film on the paint surface, effectively preventing yellowing. 3. Glaze sealing maintenance: Cars are inevitably prone to scratches, which can leave marks. Repainting can easily result in mismatched paint colors. Therefore, it is advisable to perform a glaze sealing treatment to maintain the paint's shine.
I've been driving a sedan to commute and found that stain treatment depends on the type. Bird droppings are the most common and troublesome because their high acidity can easily corrode the paint. Upon discovery, immediately wet and soften them with water, then gently wipe along the paint grain with a soft cloth or sponge—avoid pressing hard to prevent scratches. For stubborn stains, spray automotive-specific car wash liquid on the stain, wait a few minutes, and rinse thoroughly. When parking, try to avoid spots under trees to reduce the risk of bird droppings. After washing, applying wax is best to protect the paint, forming a protective film that makes stains less likely to stick. Also, avoid using household detergents or strong acid/alkaline cleaners, as they may damage the paint's gloss. In short, simple stains can be handled yourself, but when in doubt, visiting a professional shop is safest—saving effort and protecting the paint.
