Abstract: A cleaning apparatus (10) is disclosed for cleaning the leg sections (16) of forms such as a double leg form (12). A plurality of individual cleaning brushes (76) are positioned along the length of a brush shaft (64). The brush shaft (64) and cleaning brushes (76) are rotated and the cleaning brushes (76) are urged against the sloping sides (24) of the leg section (16) to clean the sides. As the brushes wear, they can be moved along the shaft in the direction where the sides slope together to obtain maximum use from the brushes. When a brush has become too worn to be effective, it is removed from the section of the brush shaft adjacent the end plate (84). Replacement brushes can be added to the brush shaft adjacent the locking nut (88).
