Abstract
Methods and systems are disclosed for cleaning a rear view vehicle camera. An example vehicle camera cleaning system includes a camera, a blade for cleaning a lens of the camera, a fluid reservoir for dispensing fluid using gravity via a one-directional gateway valve, and an actuator for moving the blade vertically across the lens, wherein the fluid reservoir dispenses fluid responsive to actuation of the blade.
