An improved chimney cleaner for removing soot from the insides of chimneys. A lower plate is orthogonally connected to a vertical support member. An upper plate, which is the same shape as but smaller than the lower plate, is located over and concentric with the lower plate, so that the vertical support member passes slidably through the upper plate. Cleaning rods are connected to the perimeter of the upper plate, and pass slidably through holes near the perimeter of the lower plate, ending in scraping portions which engage the chimney walls and do the actual soot removal. A support line is attached to the top of the vertical support member, to be pulled by the operator during the cleaning operation. A control line is also attached to the top of the vertical support member. This line is then threaded through an eyelet connected to the upper plate, and held by the operator. When the cleaner becomes snagged on a protrusion on the inside wall, the operator pulls this control line, which forces the upper and lower plates apart, in turn pulling the scraping portions of the cleaning rods inward away fron the protrusion, unsnagging the cleaner.
