What Causes Oxidation Spots on the Car Windshield?

[Penelope]

Cars often stay outdoors, enduring wind, sun, and rain, making them prone to getting dirty. On rainy days, if the car is not in use and the rainwater on it is not cleaned promptly, water stains or rust spots can easily appear on the glass after the water evaporates. Below are some relevant solutions: Vinegar: Car glass rust spots can be removed with vinegar, which reacts with rust. Spray vinegar on the rust spots, let it sit for a short time to soften, then wipe with a towel and rinse thoroughly. This effectively removes rust spots. Clay bar: Clay bars have a polishing effect and can remove glass rust spots. To use, first rinse the glass surface clean, then rub the clay bar over the rust spots, and finally rinse thoroughly. Polishing: For stubborn rust spots and grime, polishing is the last resort. Using a polisher with polishing liquid or powder can remove rust spots, restore the glass's cleanliness, clarity, and transparency, and also eliminate tiny surface pores, effectively preventing oil film formation.
