There is no excuse, but with the pressure to turn around the plane quickly, I suspect the cleaners have only a limited time to do a superficial clean.
As most VS aircraft spend the least amount of their life on the ground at LHR (a typical LHR turnround being between 3 and 4 hours for a 744) the aircraft need to be rotated through downline locations where there are longer layovers (such as JNB, SYD and MIA).
There, VS can engage the local cleaners to perform a more thorough cleaning, or if the sub-fleet's normal work doesn't take it to one of these places, be scheduled to be 'down' at LHR/LGW for more than the usual 3 hours, to allow for a heavier cleaning once a week.
I think the 744 suffers the worst, as it mostly flies UK-US flights, it's a relatively small fleet with little slack, and therefore has relatively short turnarounds at both ends of the trip.
So I wondered how this might work. Looking at the LHR 744 fleet, take the aircraft arriving off the VS46 (around 7am) and rather than do a quick turnaround to go back out on the VS19, send it on the VS1 or VS9 instead (4pm departures), which effectively doubles the time that aircraft has on the ground.
If the aircraft rotate around the various 744 operated flights, in theory, each of the five LHR 744s will get a more intensive clean than can be achieved during the standard turnround each week, and it should prevent the buildup of the ingrained muck we currently see.
It seems the current situation is to allow muck to build up over a period of several weeks, because turnaround cleans seem to be little more than litter picks, then stop the aircraft for a day or more and try to blitz it.
The fact is, Air New Zealand have a similar onboard config (UCS, PE, and regular Y cabins), their eight 744s are used almost as heavily, yet they still manage to keep them very clean inside.
So it's either bad specifications and broken processes, or lazy cleaners, with insufficient quality control. (Or possibly VS just have dirtier, messier pax?)
