The local fire brigade was in charge of the massive 4-day operation, using recycled water. Officers say due to the Stadium's design and weather conditions, the cleaning was mainly carried out during the day time.
A special coating on the steel in the structure should rule out any corrosion problems from the high-pressure washing. The Bird's Nest was turned into a major tourist attraction after the Olympics, so the seats also get a good cleaning every day.
