How can i remove dried concrete from off of my car?

Yesterday i went out to find my car had been splattered in concrete/cement due to building on the plot next to me.there is a high fence between this plot(which we put up) which has no splashes on that side - i forgot to mention that the guy who owns this plot has been somewhat of a problem from the start and so it didnt surprise me to have concrete on the car.what i want to know is; as it is hard, it wont scape off without scratching the paint and so if someone knows how to get it off,id be grateful.ironic as yesterday i posted a question about cleaning houses now ive got to clean my car!!nb. the car is a kreg clio but it is besides the point.
