i think you mean "gouge" but you aren't going to hurt a steel rotor that sees 1200+ degrees and thousands of lb-ft of torque sticking something in the holes to clear them. You know the inboard face of the rotor has holes in it too, right? How well does spraying water clean the inboard side? What happens when a clod of wet brake dust gets stuck in a vane? It turns to cement as soon as it dries.
