Place walk off mats or area rugs at each entryway to collect dirt and grit that might be tracked in. These tiny particles act like sandpaper and will scratch your floor.
Be sure to avoid using rubber-backed or non-ventilated mats or rugs as they can damage your floor. Instead use mats or rugs made especially for hardwood floors and remember to shake them out regularly.
In addition to entryways, remember to place mats in any areas where water may be splashed, such as near a kitchen sink.
