Dirt buildup

Q: I recently purchased a home that was built circa 1921. The home has the original hardwood floors throughout, oak with a maple inlay. They have been covered with carpeting for many years and are in good shape structurally, but they are very dirty. I have been told that they do not need to be sanded. However, they do need to be cleaned thoroughly and buffed. I am seeking advice as to what product would best remove the dirt buildup without destroying the finish that still exists.

A: If this is a wax finish, Dura Seal renovator would be a good choice. www.duraseal.com

If it is a varnish or polyurethane, any polyurethane cleaner would be best, such as Bona Pacific Floor Cleaner. www.bonakemi.com
