Narrative:

Unsatisfactory deice at ord. Relief first officer arrived at aircraft at XA05 local. Captain and first officer at XA20 local. All aircraft were being deiced at ord due to freezing rain. Aircraft had been at hangar all day and had accumulated ice and snow in considerable amounts. Relief first officer confirmed that we would need to be deiced and reported the amounts of snow. Aircraft was closed at XB30 local and deice commenced at XB35 local using type I and ii. Captain was advised before deice start and deice complete with holdover start time of XB35 local. Captain was advised deice complete at XB40 local. Captain asked for push crew as soon as possible and, when push driver reported on, released brakes at XB41 local. The left wingwalker stopped everything at that point by telling the driver that the left wing still had visible snow and ice on leading edge and engine cowling. Captain called for deice again. When the deice coordinator reported on the interphone, captain told him to do both wings and tail again since the holdover time had already expired. Second deice began at XC05 local. Only the left wing was done. Captain called for the deice to return. Finally, at XC15 local, our second deice was complete. We departed at the limit of holdover time since there was no falling moisture noted during taxi out. Excuses about shift change and lunch do not cut it. Kudos to ground push crew. The deice inspectors and operators need, in captain's opinion, to be retrained for work in less critical area. This could have ended in disaster and the critical nature of the mistake, missing the entire left wing, cannot/must not ever happen again. I hope that this is made clear to deice people.
