A flue brush is a specialized cleaning tool designed to remove soot, creosote, and debris from the flue of a chimney. It typically features a long handle and a bristle head, which can be made from various materials like nylon or wire. Regular use of a flue brush helps maintain chimney efficiency and reduces the risk of chimney fires. Using a flue brush is essential for homeowners with heating systems that rely on a chimney, such as wood stoves, fireplaces, or furnaces. Proper maintenance ensures safe operation and prolongs the lifespan of the chimney, making it an important tool for home safety.
