I was watching some sort of home improvement show on television and I saw them using olive oil to refinish furniture and they weren't even trying to be green. I felt compelled to give it a try because I have always been pretty frightened of furniture polish. Store-bought furniture polish is the farthest thing from green and can irritate the respiratory systems in some individuals. And Collin wrote a while back about the importance of staying away from furniture finishes laden with VOCs. Olive oil doesn't have the thick coating of a varnish but it does protect woods from simple scratches and drink rings.
