In order to bleed the clutch, you will need to remove all fluid from the reservoir and top off the fluid with fresh fluid. Then remove the washer bolt from the slave cylinder and give it a few presses on the clutch pedal. Dirty fluid should be released at first. Then you will have to top off the fluid and do the same thing again and again till clean brake fluid starts to come from the slave cylinder. Once you are done, tighten up the bolt and you are good to go.
