How to Remove Cement from Car Body?

Primarily, hot water can react with certain components in cement, making it brittle. First, cover the cement spots with a towel, pour hot water over them, and let it sit for a while until the cement becomes brittle. First, use a small spray bottle (such as a gel bottle) filled with white vinegar, spray it on the cement, let it sit for a while, then rinse with water. Repeat this process several times. You need to buy a bottle of oxalic acid, then dip a towel in it and apply it to the cement spots. Wait a few minutes, then scrub off with a brush and rinse with water. This method works well. Oxalic acid is somewhat corrosive, so safety precautions should be taken when using it.
