Narrative:

During pre-flight of aircraft; it was determined that due to excessive amounts of airframe ice; aircraft needed to be de-iced. After being de-iced and received de-ice report; and told that aircraft was clean; we continued with taxi whereupon we noticed ice still adhering to the windshield wipers. I decided to return to the gate to have the first officer further inspect aircraft for other signs of ice and found aircraft still had large amounts of ice adhering to the tail; winglets; flaps and radome. I informed the ground crew that the aircraft needed to be de-iced again whereupon aircraft was de-iced for a second time. I instructed first officer to perform another check and he reported ice still adhering to airframe. After this I spoke directly to the gentleman de-icing the aircraft who informed me that it was his first time de-icing an aircraft and asked what else he should do. I explained company's 'clean aircraft' policy and informed him that he needed to get out of truck to reach some parts of the airframe and how all ice needed to be removed in order to depart safely. After 3 attempts at de-icing the airframe it was determined that the aircraft was finally safe for flight operations. De-ice ground crew should receive better training on use of and procedures for de-icing aircraft. Supervision should be provided by the station to ensure these events do not transpire again.

Narrative: DURING PRE-FLIGHT OF AIRCRAFT; IT WAS DETERMINED THAT DUE TO EXCESSIVE AMOUNTS OF AIRFRAME ICE; AIRCRAFT NEEDED TO BE DE-ICED. AFTER BEING DE-ICED AND RECEIVED DE-ICE REPORT; AND TOLD THAT AIRCRAFT WAS CLEAN; WE CONTINUED WITH TAXI WHEREUPON WE NOTICED ICE STILL ADHERING TO THE WINDSHIELD WIPERS.
