The invention is an adjustable wire brush tool for cleaning either the inside or the outside end of a copper pipe or fitting in preparation for soldering the parts together. The tool includes a hollow cylindrical section with a first wire brush on the interior surface of the section. Attached at one end of the cylindrical section is a slightly smaller cylindrical section sized to hold a second cylindrical twisted steel brush having a hexagonal shaft that extends from the smaller section, opposite the larger cylindrical section. The twisted steel brush and attached shaft can be moved to extend the twisted brush beyond the open end of the larger cylindrical section, for insertion into a fitting to clean the fitting interior surface by attaching a power drill to the shaft and rotating the twisted steel brush attached thereto. To clean the outside of a pipe, the twist brush is retracted into the smaller section and secured to that section with an engaging means. The pipe is inserted into the larger section, and the drill is activated to rotate the shaft and attached larger section to clean the pipe outer surface. The tool overcomes the need for separate tools to perform each task and requires but one drill to perform either task as needed. The tool is sized to handle a particular diameter of pipe and fitting, with sizes ranging from one quarter inch to several inches.
