Narrative:

Arrived at gate; conferred with operations and deice crew as to coordination for deicing aircraft. Deiced at gate in light-moderate snow. Pushed back at ZZZ. Type 4 fluid applied. 1+45 holdover time calculated. Taxied for takeoff to runway. Taxi time approximately 6 mins. Upon wing inspection first officer observed 1/4-1/2 inch snow and slush adhering to leading edge as well as entire top portion of both wings. Coordinated a second deicing crew in the deicing pad. Upon arriving and looking at the wings; the deice crew was reluctant to spray the wing a second time; commenting that they felt the wing was clean and that the mixture would blow off the wing on takeoff. After the second deicing the wing was still not clean; and we requested a third deicing and a close inspection of the wing by the crew. They physically felt the wing and observed that there was no ice present. Both the first officer and myself now felt that the wings were clear enough and we were safe to continue. The snow had also stopped. In our opinion there was clearly something wrong with the fluid that was being applied; it did not look or behave like any type 4 we had previously been exposed to. I contacted operations on landing and they assured me that ZZZ had inspected the fluid and cleared it for use. This was last year's fluid.

UPON ARRIVING AND LOOKING AT THE WINGS; THE DEICE CREW WAS RELUCTANT TO SPRAY THE WING A SECOND TIME; COMMENTING THAT THEY FELT THE WING WAS CLEAN AND THAT THE MIXTURE WOULD BLOW OFF THE WING ON TKOF. AFTER THE SECOND DEICING THE WING WAS STILL NOT CLEAN; AND WE REQUESTED A THIRD DEICING AND A CLOSE INSPECTION OF THE WING BY THE CREW. THEY PHYSICALLY FELT THE WING AND OBSERVED THAT THERE WAS NO ICE PRESENT. BOTH THE FO AND MYSELF NOW FELT THAT THE WINGS WERE CLR ENOUGH AND WE WERE SAFE TO CONTINUE. THE SNOW HAD ALSO STOPPED. IN OUR OPINION THERE WAS CLRLY SOMETHING WRONG WITH THE FLUID THAT WAS BEING APPLIED; IT DID NOT LOOK OR BEHAVE LIKE ANY TYPE 4 WE HAD PREVIOUSLY BEEN EXPOSED TO.
