A duster is a cleaning tool used for removing dust and dirt from furniture, top surfaces, and other objects in the home such as doorframes, baseboards, table legs, electronics, and appliances. It can be made of natural or synthetic materials. A duster “scatters” dirt in the air, allowing it to settle on the floor where a vacuum cleaner, mop, or broom can finally clean it. It should be used before cleaning floors, walls and other major surfaces. Dusting is usually done from top to bottom.
