Use a dust mop, soft bristle broom or a vacuum cleaner with suction only (no beater bar or with the beater bar disengaged) to remove dust, dirt and loose particulate on a regular basis. Avoid wet-mop cleaning with water or liquid cleaners.
Use protective window coverings to block fade-causing UV rays and excessive heat from direct sunlight, and rearrange rugs and furniture periodically to help your floor age evenly. During inclement weather, avoid exposing your flooring to water as much as possible.
