For gleaming hardwood floors, try giving them a polish with old-fashioned wax. Wax can only be applied to certain flooring types, such as unvarnished hardwood or concrete, so be sure to check your flooring type and the label on the can of wax before beginning. Apply the wax evenly over the floor using a lint-free rag. Once dry, buff the surface with a clean sponge mop or dry towel. You'll be left with shining floors that make the whole house look new.
