Abstract: A rotary terminal cleaner for cleaning terminals such as on automotive batteries and the like includes a cylindrical housing having an internal key running along the housing, an end cap having a cylindrical shape for mating with the hollow housing and forming a snug fit within an end of the hollow housing, the end cap having a longitudinal slot to mate with the key of the housing to prevent relative rotation of the end cap and the housing, the end cap also having a shaft integrally formed with the end cap for driving the cleaner by a rotary device such as a power drill. The cleaner also includes first and second brushes of abrasive material which fit within the hollow housing to abrade and clean the terminals. The first brush is a rectangular piece of abrasive material perhaps having bristles such as a section of a wire brush which fits in the end cap in such a manner as to permit the bristles to be facing the open end of the hollow housing.
