My wife sat down in 53K, CW on A380 G-XLED, on 1 Jan and immediately asked one of the CC for a cleaning cloth - there were food/liquid splashes all over the IFE screen and the top of the side bin. These were not just occasional spots, but a liberal splashing of 'something' all over the area.
Decidedly substandard cleaning of obvious, customer-facing, surfaces.
