3 Answers
Methods to remove cement stains from a vehicle include: 1. Rinse off the cement stains with clean water before they harden; 2. Spray white vinegar or a specialized cement cleaner on the stains, wait for them to soften, and then rinse with clean water; 3. Pour gasoline on the stains, wait for the car paint to soften, and then wash off the cement stains with water. Methods for car paint maintenance: 1. Avoid touching the car's paint with oily hands or wiping it with oily cloths; 2. If there are no obvious scratches on the paint, avoid repainting to prevent color mismatch or poor adhesion; 3. Prevent strong impacts, knocks, or scratches on the car's paint film.
When I first bought my new car, I once parked it near a construction site, and the wheels got covered in wet cement. I immediately rushed over and used a high-pressure water gun to rinse it off, then wiped it with a soft cloth. But the next day, the cement had dried. I went to the supermarket and bought a specialized cement remover, sprayed it on, let it sit for ten minutes, and then gently scraped it off with a plastic scraper. Never use metal tools or hard objects, as they can scratch the paint. As a preventive measure, try to avoid parking in high-risk areas, such as newly built roadside spots. If the cement covers a large area, it's best to take it to a professional car wash—they have gentle equipment that won’t damage the car body. Maintaining regular cleaning habits while using your car can help reduce such troubles.
From my car repair experience, dealing with cement stains requires different approaches based on the situation. Fresh cement can be removed by rinsing with plenty of water and gently brushing with a soft brush; for dried cement, you'll need to use an acidic remover, such as commercially available cement cleaning sprays. Apply the spray, wait for it to soften the cement, and then wipe it off with a soft cloth. Be careful not to scrape too hard in a rush, as this can damage the primer and make polishing more time-consuming and labor-intensive. For prevention, avoid parking near concrete mixing sites or newly constructed roads. Regular car washing can enhance the paint's resistance to stains.
