Cleaning Tar From Your Car

I use kerosene. Put a little on a rag and gently rub the places where there is tar and it will disolve and come off with no harm to the paint.

Use Goo-gone. You can purchase it at Wal-Mart.

WD 40.

Don't know of any "home" things other than maybe kerosene. They used to sell a tar remover at local automotive stores like PepBoys, Hi Gear and Advanced Auto. they probably still due and the stuff worked great. At least it did back in '95. It was called Tar and Bug Remover.
