How to Deal with Stubborn Marks on the Windshield?
2 Answers
Take one dry and one wet cloth. First, wipe both sides of the glass with the wet cloth, then use the dry cloth dipped in a small amount of alcohol or high-proof liquor to scrub the glass vigorously. Use clay bar, wet the glass, and rub back and forth on the areas with watermarks to effectively remove them. Apply dishwashing liquid to a towel and then wipe the glass, which can also remove watermarks with good results. Spray vinegar or soda water on the glass stains, wipe with a towel, and finally rinse with clean water. Pour a cleaning agent on a towel or sponge, scrub the water stain and dirt, then rinse with clean water, and finally dry with a soft, clean towel.
As a seasoned driver with over twenty years of experience, I often encounter stubborn stains on the windshield. These marks are mostly caused by long-term accumulation of tree sap, water scale, or external pollutants. I've tried wiping them with a regular cloth, but it didn't work, so I switched to using a specialized glass cleaner bought from the supermarket, spraying it on and gently wiping in circular motions with a microfiber cloth, which worked somewhat. If the stains still won't come off, never use hard objects to scrape the glass, as this can cause scratches that make driving in strong sunlight dangerous due to blurred vision, potentially leading to accidents. I would recommend going to a professional repair shop or a 4S store for inspection—they can safely handle deep-seated stains with a polishing machine. Also, pay attention to whether it's an internal issue, such as stains reflected from a dirty air conditioner evaporator, which requires separate cleaning. In short, safety comes first—don't take risks. Before attempting any cleaning, park the car and ensure it doesn't obstruct your view.
