Emirates showcases environment friendly aircraft cleaning technique

On the occasion of World Environment Day, Emirates is showcasing an environmentally friendly aircraft cleaning technique that has enabled the airline to save millions of litres of water every year.

Emirates uses the ‘aircraft drywash’ technique to clean its aircraft. As indicated by the name, little or no water is involved in cleaning the aircraft, which is in contrast to conventional methods of aircraft cleaning which typically use thousands of litres of water per wash.

During the course of every flight, an aircraft accumulates dust and grime on its external surface. In addition to making the aircraft look dirty and less appealing, the dirt that accumulates on the aircraft surface also increases the fuel it consumes by making the aircraft heavier and less aerodynamic.

Traditionally aircraft are cleaned by using highly pressurised water between four to five times every year.

However, on an average this technique uses more than 11,300 litres of water to clean one Airbus A380 aircraft and more than 9,500 litres of water to clean a Boeing 777 aircraft every time.

Since early 2016 Emirates has been using an aircraft drywash technique to clean its fleet of over 250 aircraft. In this technique, a liquid cleaning product is first applied manually to the entire external surface of the aircraft.

Clean microfibre fabric is then used to remove the cleaning product which has dried to a film, removing the dirt along with it and leaving the aircraft clean and polished.

The aircraft is left with a fine protective film allowing the painted surface to retain a longer gloss and shine. It takes a crew of 15 staff about 12 hours to clean an A380 and about 9 hours to clean a Boeing 777 aircraft.
