Has anyone removed their focus screen for cleaning? While I clean the sensor all the time, I've never tackled the focus screen. After this past trip, I have a couple dust bunnies sitting on top of it and need to get it spotless again. I've seen some D3/D700 removal videos on YouTube but I'm reluctant to give it a go without a little more research first.

It appears it works the same as the D700/D3 where a retainer bar holds it in place. The bar clips under the latch in the center of the screen when you hold the camera upside down and look into the shutter box. The latch is in the cutout in the foam along the top-front edge. I think I'm just going to send it in for cleaning...there shouldn't be dust up there anyway and Nikon can take care of it. I'd guess it's their fault and didn't get it cleaned well during my AF adjustment and 'cleaning' a couple months ago.
Do you actually see the dust? If you do and you think it is just a dust and not something else like dead bug or oil just go to your art store and get $3 softest nylon brush they have. Make sure it is a nylon. Wash it with soft soap at least 3 times and let it dry because it has glue on it. All you need now is something with high velocity air. I use http://www.adorama.com/CPDVED.html?kbid=912610 though I paid a lot less. Just blow this filtered air on the brush for a few seconds until it statically charges. It will remove dust from the mirror and censor too. This brush is my standard part of the cleaning kit.
I've cleaned the mirror as well as the bottom of the focusing screen and viewfinder. The dirt (it's somewhat bigger than dust) is still visible on the matte through the viewfinder. It's somewhere between the viewfinder on the back of the camera and the top of the focusing screen. Not brushable unfortunately.
