Narrative:
We requested deicing at slc. We were informed that deicing was accomplished on wings and tail by a certified deicer. At that time, icing conditions ceased when precipitation stopped. Takeoff and climb out were normal. We were notified by a flight attendant that a passenger could see ice on the wing. Pilot verified that ice was on the wing in cruise flight. This same passenger was a certified deicer from another airport for 11 different airlines. He said that the deicing was inadequate, that deicer never checked the wing after deicing, and that the type 1 fluid was not steaming, indicating that the fluid was not hot (as is required). The flight was continued to destination and landing was uneventful. The passenger also stated that large sheets of ice separated from the wing during takeoff rotation. Ice covered entire area of wings and was approximately 1 inch thick.

Title: MLG DEPARTS AFTER DEICING. PAX NOTIFIES THAT DEICING WAS NOT PROPERLY ACCOMPLISHED. ICE STILL ON WINGS AT TKOF.
Narrative: WE REQUESTED DEICING AT SLC. WE WERE INFORMED THAT DEICING WAS ACCOMPLISHED ON WINGS AND TAIL BY A CERTIFIED DEICER. AT THAT TIME, ICING CONDITIONS CEASED WHEN PRECIPITATION STOPPED. TKOF AND CLBOUT WERE NORMAL. WE WERE NOTIFIED BY A FLT ATTENDANT THAT A PAX COULD SEE ICE ON THE WING. PLT VERIFIED THAT ICE WAS ON THE WING IN CRUISE FLT. THIS SAME PAX WAS A CERTIFIED DEICER FROM ANOTHER ARPT FOR 11 DIFFERENT AIRLINES. HE SAID THAT THE DEICING WAS INADEQUATE, THAT DEICER NEVER CHKED THE WING AFTER DEICING, AND THAT THE TYPE 1 FLUID WAS NOT STEAMING, INDICATING THAT THE FLUID WAS NOT HOT (AS IS REQUIRED). THE FLT WAS CONTINUED TO DEST AND LNDG WAS UNEVENTFUL. THE PAX ALSO STATED THAT LARGE SHEETS OF ICE SEPARATED FROM THE WING DURING TKOF ROTATION. ICE COVERED ENTIRE AREA OF WINGS AND WAS APPROX 1 INCH THICK.
