A duster is a type of clothing or accessory that is designed to keep dust off of surfaces. It can refer to a long-sleeved garment made from lightweight fabric, often worn over other clothes for protection while working in dusty environments such as construction sites or factories. A duster can also be used to describe an item of clothing with a long flowing shape that is designed to drape elegantly over the body, such as a trench coat or cape. In some cases, "duster" may refer specifically to a type of cleaning tool, typically made from microfiber material, which can be used to wipe down surfaces and remove dust without leaving any residue behind.
