Use a well rung out damp cloth to clean up any dirt and footprints but avoid using excessive moisture.  All spills should be cleaned up immediately.  Never use wax, polish or scouring agents as they may dull or distort the finish.  You can use acetone or a cleaner specially formulated for laminate to remove stubborn marks.  To avoid scratches apply felt pads to your furniture legs and use only soft rubber casters.  Protect high traffic areas with runners and rugs.  It's a good idea to save a few boards in case of accidental damage.  Boards can be replaced if damaged.
