ABSTRACT:
An apparatus and method for polishing a metallic plumbing or electrical fixture, such as a pipe, pipe fitting or electrical bus bar, is provided. The apparatus includes container means for retaining an electrolytic solution and a cathode member. The member is specially designed to accommodate a plumbing fixture having a circular cross-section or an elongate electrical fixture, and is at least partially immersed within the solution. The apparatus also includes dc power supply means having a negative terminal, which is connected to the cathode member, and a positive terminal which is connected to a clamp means. The clamp means is capable of forming an electrical connection with the fixture to be polished. When the clamp means is secured to the fixture and the fixture is positioned near the cathode member, polishing of the fixture occurs. In an enhanced embodiment, the cathode member includes a first column which extends above the electrolytic solution and which is surrounded by a wicking material capable of drawing the solution from the container means to the free end of the column such that a fixture does not have to be immersed within the electrolytic solution to be polished. A related method for polishing a plumbing fixture having a circular cross-section or an elongate electrical fixture is also provided.
