When is al-Kaaba al-Musharrafa Washed?

Al-Kaaba al-Musharrafa, located in the Grand Mosque in Makkah al-Mukarramah, is washed on the fifteenth of Muharram each Hijri year. Before the washing, it is cleaned with four straw brooms that have silver handles, used to sweep away dust. These brooms are inscribed with the phrase: "This is the glorious Kaaba, how fragrant is its aroma and how pure are the walls washed with light."

A set of tools and copper vessels are used to wash al-Kaaba al-Musharrafa, in addition to four ten-l gallons of a special mixture for washing. This mixture consists of four tolas of oud oil, along with water and rose fragrance mixed with Zamzam water. Four additional cloths are used to wipe the higher parts of the Kaaba's walls, while four fabric pieces with wooden handles are used to wipe the floors of al-Kaaba al-Musharrafa and dry the washing water.
