How to Remove Hardened Cement Slurry from a Car?
2 Answers
Methods for cleaning hardened cement slurry from a car: 1. Use a specialized cement cleaner to wash the car body, then rinse with clean water afterward; 2. Spray white vinegar multiple times on the cement, wait for it to soften, and then clean the car body; 3. Take the car to a professional car wash for cleaning. Cement slurry is an alkaline substance and can be cleaned with acidic cleaners. It is important to address it promptly, as cement can be corrosive and damage the car's paint. Specialized cement cleaners are effective at removing cement from the car, but due to their high acidity, they can also be corrosive to both skin and car paint. Therefore, the cleaning process should be quick, avoid skin contact, and prevent the cleaner from staying on the car body for too long.
I had cement splashed on my car before, and it was such a headache. At the time, I didn't know any better and tried washing it off with water for a long time, but it didn't work. Later, a friend taught me to buy a bottle of white vinegar, pour it on the cement spots, and let it soak for two hours until the cement softened. Then, I could gently scrape it off with an old credit card. If the cement covers a large area, you can buy a professional cement cleaner—spray it on, and it will dissolve in about ten minutes. Be careful not to use metal scrapers or knives when scraping, as they can scratch the car paint, which would be a huge loss. After removing the cement, rinse it immediately with clean water and apply a coat of car wax to protect the paint. Usually, try to avoid parking near construction areas, and wash off any cement splashes promptly to save trouble.
