Aircraft; Procedure
After deicing with Type One and Type Four fluid; we ran the appropriate checklist and waited one minute to turn on the engine bleeds (both engines were running). Almost immediately; a fog started to form along with the fluid smell. We decided to turn the bleeds off because we were [planning] to accomplish a no bleeds takeoff. Approximately five minutes later we were cleared for takeoff on 31C. Once airborne; the cockpit filled with the deice fluid fog to the point I couldn't see my instrument panel. The Captain was the pilot flying and seemed to have better visibility on his side; so we decided to reconfigure the pressurization panel prior to retracting the flaps (gear was up) and the fog dissipated rather quickly. After flaps were retracted; the Captain called the flight attendants and spoke to the passengers to reassure them. We continued to our destination without further incident.
B737-700 FO reported the cockpit filled with de-ice fluid fog shortly after takeoff. Fog cleared and flight continued to destination.
