MAKKAH – The Presidency for the Affairs of the Two Holy Mosques is exerting great efforts to clean and perfume the Grand Mosque daily, including wiping and sterilizing its floors, surfaces and piazzas, with a total area estimated at one million square meters, Saudi Press Agency reported on Monday. The presidency has hired over 2,000 male and female workers, who are available round-the-clock, working in four shifts. Cleaning the whole Grand Mosque takes only 45 minutes, without obstructing the pilgrims, visitors and worshipers from carrying out their rites. Cleaning of the circumambulation area (the Mataf) takes only 30 minutes and is carried out swiftly in a highly technical fashion, amid dense crowds of the faithful. Some 30 special electrical cars, 67 other machines and 400 liters of water are used for cleaning and sterilizing the Mataf. The average quantity of water used for the cleaning process is one glassful of water for 12 sq. meters of the Mataf, whose area is nearly 500 sq. meters. Cleaning equipment and implements are not harmful and are environment friendly. The same applies to the detergents. They are organic and safe.
