How to Remove Cement Splashed on the Car?
2 Answers
There are several methods to remove cement from the car: 1. If it's within 12 hours: First, wet and soak the area with water, then use car wash liquid and a towel to gently clean it. 2. If it's over 12 hours: By this time, the cement has likely hardened. You can purchase some acidic solution from a pharmacy, dip a brush in it, and apply it to the cement. The cement will dissolve in the acidic liquid, and then you can rinse it off with water. 3. Using gasoline: Pour gasoline onto the cement, wait for it to soften slightly, and then remove the cement by hand (suitable for large-area removal). 4. Using a hairdryer: Heat the cement-splashed area with a hairdryer. Due to the different thermal expansion of cement and plastic, the cement will usually fall off automatically. 5. Using white vinegar: Spray white vinegar onto the cement with a spray bottle, wait for 3-5 minutes, and then gently scrape it off with a hard card. The cement will come off in chunks. Afterward, wash the area where white vinegar was sprayed with car wash liquid to ensure no residue remains.
Last time I was working at the construction site, I parked my car too close and the body got splattered with cement spots. At first, I panicked and rinsed it directly with cold water, but after it dried, it became even harder to clean. Later, a mechanic buddy taught me: first soak those cement spots with a wet cloth or sponge, letting the water slowly penetrate for a few minutes; once they soften a bit, apply some neutral dish soap water and gently wipe, avoiding too much force to prevent scratching the paint. If the cement is as hard as a rock, try pouring some white vinegar on a cloth, apply it for about 10 minutes to dissolve the cement; or buy a specialized cement remover spray, spray it on, wait 5 minutes, and wipe it off with a sponge. After rinsing, it’s best to apply a layer of wax to protect the paint. Remember to act quickly—cement is highly alkaline and can damage the car over time. Next time, I’ll park away from construction sites—much less hassle.
