Clean dried concrete from a car using a commercial concrete stain remover to dissolve the concrete, and then wash the vehicle. Avoid any mechanical means of removing the stain, as they may damage the car's finish. The concrete must be liquefied, so the process takes several hours.Know More
Begin by washing the vehicle. Locate any dried concrete on the paint or trim of the vehicle while washing. Do not attempt to scrub away the concrete stain, but make a mental note of its location.
