Abstract
A method of cleaning at least one of grime and built-up ice off a rotor blade of a wind turbine includes, in an exemplary embodiment, positioning a rotor blade in an immobile position in a downward orientation substantially parallel to the tower, positioning a tank containing a cleaning solution directly below the rotor blade, and positioning a plurality of lifting arms adjacent the tank. The plurality of lifting arms are attached to an elliptical spray head with at least one pipe connected to the elliptical spray head and to a pump operatively coupled to the tank. The method also includes raising the lifting arms to lift the elliptical spray head to a predetermined position along a longitudinal axis of the rotor blade, pumping cleaning solution from the tank to the elliptical spray head, spraying the cleaning solution onto an outer surface of the rotor blade to clean the rotor blade, and collecting the spent cleaning solution in the tank.
