From the History Blog article Conservation of Tutankhamen’s tomb complete:
The project team found the wall paintings to be in relatively stable condition, apart from localized flaking and loss of paint that was caused by both inconsistencies in the materials used and their application, as well as damage caused by visitors. Newly designed barriers now restrict visitor access in these areas to reduce the risk of future damage. The paintings were stabilized through dust removal and reduction of coatings from previous treatments, and condition monitoring was also established to better evaluate future changes.
Also addressed were the mysterious brown spots on the wall paintings. They were already present when Carter first entered the tomb, and a comparison of the spots with historic photographs from the mid-1920s showed no new growth. To confirm this finding, DNA and chemical analysis were undertaken and confirmed the spots to be microbiological in origin but dead and thus no longer a threat. Because the spots have penetrated into the paint layer, they have not been removed since this would harm the wall paintings.
Restored, stabilized and with new lighting, ventilation and information panels, the tomb of Tutankhamen offers a much improved experience for visitors as well as more secure, controlled conditions to preserve the priceless archaeological material. That includes a few important pieces on display as well as the tomb itself: Tutankhamen’s mummy on view in an oxygen-free display case, the stone sarcophagus and the outermost coffin made of gilded wood.
