What you want to do is find an inconspicuous area of your floor to test, usually a in a corner of a room. Apply 2 drops of water directly to the floor. If white spots appear under your drops within ten minutes your floor has a wax finish. If the white spots do not appear you probably have a surface finish floor, to be sure take a coin and scratch the surface of the wood. If it does not scratch then you can be sure that your flooring has a surface finish. More details can be found at http://www.oakfloorsupplies.com.
Cleaners for Wood Flooring with a Wax Finish
You must dust mop and vacuum regularly, usually once a week. You also want to buff the floor every now and again to keep it shiny. Eventually buffing won't be enough to shine the floor, that's when you know it is time for a waxing. Before waxing, clean the entire floor with a cleaner made specifically for your type of hardwood. Apply the wax evenly across the entire area and when it is dry buff it out. You should only need to wax your floor once or twice a year.
Cleaners for Wood Flooring with a Surface Finish
Sweep and vacuum your floor regularly. Never use wax on a surface finish floor. Instead, use a surface finish to recoat a dull wood floor. Depending on the amount of traffic on the floor, you may have to apply the finish every couple of months.
