Ahead of US President Donald Trump and First Lady Melania's visit to Taj Mahal in Agra, the replicas of graves of Mughal emperor Shah Jahan and Mumtaz Mahal are also being given a facelift. A Times of India report said, the Archaeological Survey of India is conducting a clay-pack treatment for the replicas of the two graves, which is expected be completed by Friday evening. This is reportedly the first time the replicas of graves have been cleaned since the emperor and his queen were buried 368 years ago. The original graves of Shahjahan and Mumtaz lie in a chamber below the crypt containing them. As part of the restoration, a coating of lime-rich clay is applied on the damaged parts of the replicas and left to dry, after which impurities are removed from the surface with a soft brush. The TOI report added, that the huge brass chandelier installed over the two graves is also being cleaned with tamarind water.
