CLEAN & WAX
Sometimes adding wax to your hardwood floor can improve its look relatively quickly. If the floor's appearance doesn't improve with a deep clean or by buffing, adding wax may be the solution. Wax is easy to clean and buff. It is also easy to add wax to continuously improve the look of your hardwood floor.
It is proper to wax your floor once or twice a year, about as often as you would shampoo your carpet.
