Air carrier First Officer reported a concern that the deicing procedure was not completed properly and the aircraft was not free of contaminants. The crew challenged the deicing crew and further frost removal was accomplished upon ground crew inspection.

Narrative

When De-icing at MGM for first flight of day frost; we were told the aircraft was free and clear of contaminants. I expressed doubt to the CA that i did not see the deice crew target the section of the fuselage forward of the main cabin door or the nose of the aircraft. when challenged: the deicing crew answered in vaguely that the frost was gone; however; they decided to get out of the truck and check the nose of the aircraft. They then sprayed the nose of the aircraft off with type 1. The CA asked if they found more frost; and the crew responded 'yes.' It could be assumed that the crew either did not take the time to do a proper inspection; or were intentionally overlooking parts of the aircraft that did not receive Deice Fluid. Deicing crew was not prepared; possibly inadequately trained; to clear the aircraft of all frost. It is possible that they were trying to speed the process along to not cause further delay; since boarding; loading of bags; and pushing the aircraft took significantly longer than usual. I would suggest a review of the entire MGM ground workforce as many facets of their operations are lacking; or are accepting complacency.
