Have never tried it, but how about a hot water pressure washer [affil links] or steam cleaner ⇦this on eBay or Amazon [affil links] ? Probably want to mechanically remove as much as you can first, so you don't drive the tar into any porous surface. Paint thinner is a moderately decent solvent for tar, but you will have to be ready with the pressure washer/steam cleaner before it soaks into the surface, carrying the tar with it. If you use paint thinner, or another solvent, be careful where the runoff goes.

to remove tar from concrete, pour mineral turpentine ⇦this on eBay or Amazon [affil links] (Australia) on the affected areas, let the tar dissolve and remove with a high pressure water cleaner.Tough residue, in addition, will require a wire scrubbing brush.It comes up new. Cheers Rowan.
