How can I clean the dust off my focusing screen?

Hi,

5DIII 4 months old and the focusing screen (not the sensor or mirror) is full of dust.  How can I clean this?

thanks

I don't have a 5D3 but most of the bodies I've owned had a small spring loaded clip to hold that screen in place. Considering how many bodies have interchangable screens I'm thinking you screen can be removed & re inserted for this relatively easily. There's likely a YouTube video on changing screens so start with a search for one of those.

Seems that the 5D3 isn't as user friendly for this because there isn't a variety of different screens. There is a discussion going on here that you should read.
