How to Remove Cement Spots from a Car?

[Nunes]

Here are the methods to remove cement spots from a car: 1. Acidic Water: You can purchase some acidic water (hydrochloric acid) from a pharmacy, then use a brush to apply it to the areas with cement. Since cement is alkaline, the acidic water can gradually dissolve it, after which you can rinse it off with clean water. Household white vinegar also has some effect, but due to its weaker acidity, it may take longer. 2. Gasoline: For larger areas of cement splashed on the car body, it's best to spray gasoline onto the paint, which will soften the cement. Once softened, you can peel it off by hand and then wash the area thoroughly with car wash liquid. 3. Hair Dryer: Heating the hardened cement with a hair dryer can also help remove it. Due to the different thermal expansion rates of cement and the car body, heating it to a certain degree will cause it to fall off automatically. Of course, you should still wash the area afterward, as some marks may remain.
