Narrative:

After aircraft was secured for push; we were de-iced due to overnight frost. The iceman communicated to us de-icing was complete and the aircraft was free of frozen contaminants. After engine start; the flight attendant called us and informed us that an overwing passenger (who is also a company pilot) wanted us to know that there was still visible frost on the wings. We called the ice crew back and queried them and asked to be de-iced again and to make sure it was done thoroughly and correctly. During communication with the iceman; it seemed clear they were not using proper phraseology and may have been unsure as to what their exact duties were. They proceeded to de-ice the aircraft a second time and then declared they were finished. I had to query as to whether or not the aircraft was now free of frozen contamination. They declared that yes it was; and we continued uneventfullyi feel that this atlanta ground de-ice crew was not following proper procedures. It is obviously imperative they do a thorough job. If not for the intervention of the company pilot; we would have been inadequately de-iced.
