I've somehow managed to get a little grime behind the focus screen (the one with the focus point squares printed on) on my 300D. It's on the inside, not the under-side visible from the open body.
I can't seem to get rid by means of air-bulb blowing. Is there any way I can get in there to give it a clean without damaging the camera?

TheMachine,

You are in P&S Canon forum, go down to Canon dslr and post the question, someone might have the best way to do it.

You have a dark spot on the mirror, not affecting the pictures, but very annoying.

BTW, congratulation on your new camera, go to Canon dslr camp, it's your new home.

Ah... My bad. I've re-posted. Could a mod please remove this thread
