Thanks for the well explained process for cleaning a sensor. I took my D600 to the beach today for some lighthouse photos and picked up a grain of sand or something halfway through the day. I switched lenses a couple of times and apparently did not do a good enough job keeping the sand on the beach instead of in my gear. I was sitting here trying to figure out how to clean the sensor when I spotted this thread. I followed your instructions and am now dust-free. Super simple.
