ABSTRACT:
A handle defining shank is provided and terminates at one end portion in a partial circular loop section of at least 300.degree. angular extent and equipped with generally radially outwardly projecting and circumferentially spaced bristles. The bristles are spaced along the loop section and the latter additionally includes a flexible liquid supply pipe extending therealong, including an inlet end portion supported from the other end of the shank portion. The inlet end portion of the tube is adapted for communication with the source of liquid under pressure and the extent of the flexible tube extending about the loop section includes a plurality of outlets spaced therealong opening inwardly toward the central area of the zone bound by the loop section. Further, the loop section is constructed of shape retentive but bendable and resilient material, whereby the loop section may be at least slightly expanded for engagement over a cylindrical member to be cleaned by the bristles.
