To begin with, all wood flooring will dull over time. This is normal, and everyone who has hardwood floors should expect it. Wood flooring that has a lot of foot traffic, or flooring that sits in direct sunlight will dull faster. In addition to losing its luster, wood flooring can also experience a variety of damages. This can happen when furniture is dragged over the floor; pets can cause scratches or gouging, and spilled liquids can cause staining that simple cleaning cannot remove.
