Abstract

The present invention concerns a washing tool (3) for cleaning well and onshore/offshore drilling equipment. The tool (3) includes a longitudinal tubular body with an upper end, a lower end and a central longitudinal boring therethrough. The central boring extends from the upper end for connection to a source of supply of high pressure liquid. The longitudinal tubular body has at least one washing port (2) extending through the longitudinal tubular body, and the washing port is shaped with a nozzle. The nozzle (2) on the at least one washing port is a vortex nozzle adapted to create a rotation in a liquid column surrounding the washing tool.
