Welcome to the forum.

Follow these instructions and you should clear the dust.
1. Take the lens off
2. At the top centre front under the penta prism there is a silver coloured latch - hold the camera upright and pull latch towards you with a small screwdriver (the screen mount will now drop downwards under its own weight)
3. With a pair of felt (or similar) padded tweasers lift the screen from the mount (ie don't touch the screen)
4. Clean the scree and replace with the matt side up
5. Push the mount back into place
6. Put the lens back on

Rodger, you failed to say "on no account touch the focusing screen or attempt to clean it with anything other than a blower brush or compressed air"
Taking your advice of "clean the screen" the guy may as well soak it in caustic soda to "clean" it

Sorry to be so pinickity but I F****d up the focusing screen on my istD by trying to clean it with a lens tissue .

I recal the olden days when focusing screens were made of ground glass instead of the "look at me and I scratch" plastic of today.
