Getting at tar on concrete paving

Q. How can I remove tar from the concrete paving in front of my house? Mary Mann Glen Burnie, Md.

A. Try paint thinner, kerosene, or a strong detergent. Let it remain overnight. Cover the area with a sheet of plastic so that the liquid can "work" while not evaporating too quickly. Then scrub with clear water.

Janitorial or paint stores sell many types of commercial tar removers. One such company is ProSoCo Inc., 1040 Parallel Parkway, Kansas City, KS 66104. The phone number is (913) 281-2700.

To prevent restaining, give the area several coats of a concrete sealing material which is available in paint stores.
