Reposing this from another thread. I sent mine in for cleaning and this is what I gathered from them:
Rough cleaning - 10 min waiting time (max 1 day) - just a sensor cleaning
Thorough cleaning - 2-3 days waiting time - sensor + surrounding area (mirrorbox most probably) cleaning <- apparently this is what Tokyo HQ told them to do for D600 bodies. I'm speculating so as to minimise the number of unhappy D600 owners spreading negative views about dusty D600s in the forums.
