This video shows you how to dry clean your sensor properly, explaining into details - what kind of tools is required and exactly where to clean, and some explantations about why wet cleaning is not recommended.

Of course, you can do wet cleaning but do it on your own risk, Nikon (or any other manufacturers) is not responsible to fix the damage on the sensor that is caused by wet cleaning.

Enjoy!
