My old oak floors need a cleaning big-time, and since they still have their original finish I can't use products like Orange-Glo, which can only be used on sealed floors. Wood Preen is a creamy liquid wax product that both cleans and shines, but I can only find it online and it cost almost as much to ship as it is to buy. I'm thinking I might be able to find it at a local mom-and-pop hardware store, if they still exist. Thanks in advance for your help!
