Murphy's Oil Soap was made to clean wood, and it is lovely stuff. Vinegar is a natural antiseptic. I don't know what it does to wood. I know it's bad for marble, and deadly to soap scum.

I can also reccomend Milsek Furniture Polish. It is wonderful for cleaning furniture. It will get all the old wax and assorted other gunk out, it will do for scratches. It is lovely. The stuff was invented by a cabinet maker. By the way, it smells beautiful!
