How to Remove Cement Stuck on a Car?
3 Answers
Cement stuck on a car can be removed using the following methods: 1. If the cement has been on the car for less than 12 hours, first wet and soak it with water, then use car wash soap and a towel to slowly wash it off, working on small sections at a time; 2. If the cement has been on the car for more than 12 hours, by which time it has likely hardened, you can purchase some acidic solution from a pharmacy, dip a brush in it, and apply it to the cement. The acidic liquid will dissolve the cement, which can then be rinsed off with water; 3. You can also try pouring gasoline on the cement. Once the paint softens slightly, the cement can be pried off by hand; 4. If the cement cannot be removed by any of these methods, you may have to resort to using sanding wax and a polishing wheel.
Cement sticking to the car is indeed a headache. Last time my car was parked near a construction site and got hit. First, I used a soft-bristle brush to sweep off the dry cement on the surface, then poured some white vinegar onto the cement chunks and covered them with plastic wrap for half an hour. The acidity of the vinegar helps soften the cement, and then I used a plastic scraper to slowly chip it away while rinsing with water. A special reminder: never use an iron scraper or steel wool, as they can scratch the car paint into a mess! After finishing, make sure to thoroughly wash the car with car shampoo and finally apply a layer of wax for protection. The sooner you deal with this, the better—once the cement hardens for more than three days, it becomes much harder to remove.
To deal with cement splashed on a car, the approach depends on the situation. Fresh wet cement is easiest to handle—immediately rinse it off with a hose, using a scattered water flow rather than a high-pressure jet. For hardened cement, first soften it with a wet towel, then use a professional cement cleaner. Choose a neutral spray, let it soak and break down the cement for about 10 minutes, then gently scrub in circles with a sponge. For corners and crevices, use an old toothbrush to slowly clean. After treatment, rinse thoroughly with clean water three times to prevent residual chemicals from corroding the paint. Prevention is key—stay far away from cement trucks when you see them!
