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.

- an actuating element including a main component and a handle, said main component and said handle being integral and coplanar, said main component having a first inner perimeter and a first outer perimeter;
- rotating cleaning means including at least one cleaning piece, each of said at least one cleaning piece having a plurality of cleaning elements, a second inner perimeter and a second outer perimeter, said actuating element imparting an input motion to said rotating cleaning means;
- and
- retaining means including a hub configured to fit within said first inner parameter and said second inner parameter, said retaining means having a first end and a second end, said retaining means retaining said at least one cleaning piece in contact with said actuating element.
A flange-cleaning tool, insertable between two abutting flanges when the flanges are separated, comprising:
- an actuating element,
- rotating cleaning means, said actuating element imparting an input motion to said rotating cleaning means, and
- simultaneously usable opposed cleaning surfaces integral to said rotating cleaning means.
