Abstract
Applicant has disclosed a rotating cleaning tool to clean chimneys, ductwork, venting and pipe. In the preferred embodiment, the tool includes a cylinder having: two curved channels in its bottom or proximal face; and two curved channels in a distal or upper surface. Separate strands of monofilament line and/or wire can be placed in the channels with the ends of the strands sticking out from both ends of the channels and the cylinder. An animal nest remover—a flat (or round) bar with upturned ends—can be mounted onto a central post extending from the cylinder. The remover can be used with or without the strands. Upon bolting the tool together, the strands and/or bar are held in place. By attaching the tool to a pole or rod, and rotating the rod after being inserted into the chimney, creosote and other unfriendly materials can be removed from chimneys.
