The present invention provides a portable optical fiber end face polisher that has a probe, a shuttle, a cover and a resilient actuator. The probe has a driving shaft holding a pin having two through holes. The shuttle holds the driving shaft, a supplying reel and a spooling reel. The cover guides the driving shaft to rotate axially and draws a cleaning medium from the supplying reel to pass through the through holes across a probing face of the pin to the spooling reel. The resilient actuator is mounted between a stopping base of the cover and the shuttle to recover the relative positions of the shuttle and the cover.
