ABSTRACT:
A flange-cleaning tool unites an actuating disk and integral handle with two cleaning disks in a primary embodiment. Union is achieved with a hub and bushing, both fitted through central circular apertures in the disks. The outward-facing sides of the cleaning disks are lined radially with cleaning elements, which may be, for instance, of the razor, rasp, or sandpaper type. Interspersed with the cleaning elements are debris apertures. The tool is manually or motor-powered, and incorporates a circumferential ratcheting mechanism in the primary embodiment. In a secondary embodiment, the ratcheting mechanism is located radially. Auxiliary devices may be attached for extra leverage, and a reinforcing lip on the handle makes it possible to safely apply a high impact force in difficult cleaning situations.
