1. A method of cleaning equipment, the method comprising:
providing a blasting nozzle including a body having a proximal end and a distal end, a first housing part and a second housing part, a head disposed adjacent the distal end and rotatably mounted relative to the body, the head including a jet, the body defining a plurality of longitudinal channels extending from the distal end toward the proximal end, the plurality of longitudinal channels being defined in a first exterior surface of the first housing part and a second exterior surface of the second housing part, each of the plurality of channels being separated from an adjacent channel by a respective longitudinal buttress;
advancing the nozzle axially within an elongated tube;
ejecting a liquid from the head through the jet into the tube at a pressure of at least 1000 psi to thereby rotate the head relative to the body about a longitudinal axis of rotation; and
conveying a portion of the liquid from the distal end toward the proximal end through the plurality of channels while the head rotates to evacuate the portion of liquid away from the head,
wherein the evacuation of the portion of liquid through the plurality of channels at least one of prevents and impairs hydraulicing of the nozzle in the tube when the nozzle encounters a blockage within the tube.
