A team of National Museums Scotland's conservation engineers used non-scratch mops and other special equipment to clean the iconic aircraft, which has been on show since 2005.
Next month, Concorde will be joined in her hangar by a major new exhibition, The Jet Age - featuring the front fuselage of a Boeing 707 and telling the story the aircraft played in the creation of the original 1960's jet-set.
A new Second World War parachute store is also set to open, a reminder of the role of the museum's East Fortune home as an airbase during WW2.
The National Museum of Flight has also unveiled its programme of events for the year ahead, which includes a special weekend of activities as part of the Edinburgh International Science Festival, a trip down memory lane to the days of the Second World War, a robot-inspired exploration of the future, a car-crushing Monster Truck demonstration and the attraction's popular airshow which this year takes place on July 24.
Grant MacKenzie, general manager at the National Museum of Flight said: "2010 is set to be another very exciting year for our museum so we're ensuring our most famous exhibit is spruced up for the weeks and months ahead.
"With The Jet Age exhibition and the Parachute store, as well as a host of action-packed events, our programme will appeal to all ages. We look forward to welcoming thousands of visitors to experience what is undoubtedly one of Scotland's best days out."
The National Museum of Flight is currently open at weekends. It will be open seven days a week from, Thursday, April 1 .
