Two technicians deicing a plane at Milwaukee General Mitchell International Airport in winter. They are applying Type I aircraft deicer (which is orange) to the plane. Type I deicer is typically applied hot (hence the steam) and it is used to remove existing ice and snow. This will then usually be followed with Type IV (which is green) to prevent new ice.

A technician has just finished applying Type IV aircraft anti-icing fluid (which is green) to an airplane parked at a hangar. Anti-icing fluid is applied after the plane has already been deiced and it is used to prevent new ice from forming. Type IV fluid typically shears off the fuselage during takeoff and can be deposited along runways.
