Hi..got some imprinted concrete work done. Contractor had to drive over tar drive to get to the area. Power washed drive today and found lots of small concrete splashes and footprints..power washer couldn't shift..any solutions available to remove the concrete? Thanks

use a brick acid, available at your local builders merchants

Thanks, will the acid not damage the tar, or at the least stain it as well? Looking at some other forums since..looks like acid has been recommended for a reverse situation of tar on concrete - to get the tar off. Maybe sealing with black sealant may be safest option to get all uniform again..as at the moment I got grey patches on black? Tx
