    I just bought a PhotoSol cleaning kit (Eclipse, swabs, pec-pads) online, but I forgot to specify that I needed E2, not Eclipse. I ordered some E2 and I'll be cleaning the AA filter once I get it.

    I know that crud on the focusing screen doesn't affect photos, but it's bugging the heck out of me.

    Question 1: Can I use Eclipse to clean my focusing screen? If not, can I use E2?

    Question 2: I know how to access the focusing screen, but is it a tight fit that I won't accidentally put out of alignment or is it something that requires careful calibration?

    Question 3: Does it get dirty at the top or the bottom of the focus screen? Both?

    It's held in there pretty tight by a metal retention bracket. But there's no guarantee that any crud you are seeing is actually in a cleanable place. It could be on either side of the screen, or worse still on the pentamirror the cleaning of which would require dismantling the camera.
