Various self-cleaning delineator embodiments incorporate a delineator design that includes a shell portion, a core disposed inside the shell portion, and a reflective sheet coupled to an outer surface of the core. A wind turbine mounted on or in the delineator energizes a mechanical energy storage device, such as a spring, in response to wind or other air movement. A drive mechanism couples to the storage device and is adapted to use energy from the storage device to provide relative rotational motion between the shell portion and the core. A cleaning material disposed on an inner surface of the shell contacts the reflective sheet such that the relative rotational motion between the shell portion and the first core causes the cleaning material to slide across the reflective sheet to remove debris therefrom. The drive mechanism may include an escapement mechanism to limit the rotational motion to a maximum speed.
