How to Remove Hardened Cement Slurry from a Car?

[EmeryFitz]

Methods for removing cement from a car are as follows: 1. If within 12 hours: First wet and soak the area with water, then use car wash soap and a towel to gently clean it. 2. If 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 acidic liquid will dissolve the cement, which can then be rinsed off with water. 3. Using gasoline: Pour gasoline onto the cement, wait for it to soften slightly, and then manually remove the cement (suitable for large areas). 4. Using a hair dryer: Heat the cement-covered area with a hair dryer. Due to the different thermal expansion rates 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. Afterwards, wash the area thoroughly with car wash soap to ensure no residue remains.
