Dear All,

I'm new to all this photography stuff and was wondering if someone could
advise me. I noticed that I have got some dust/hair(?) on the mirror inside
the camera, I guess when changing the lens. I've tried using a blow brush
but it just seems to get worse. What is the best way to clean the mirror and
focusing screen. Any help will be greatly received. Thanks in advance.

Cheers

Simon

Best way, compressed air in a can, holding the camera body so the
mirror points down and the air shoots up.

Photo stores and computer stores both sell it.

Don't touch the mirror with your finger and don't use any cleaning
solution. For recalcitrant dust, fog the mirror with your breath,
gently rub the mirror with a piece of lens cleaning paper or a lens
cloth.

Using compessed air on a mirror is a great way to screw it up. They are a
bit fragile. A small brush and gentle wiping (NO pressure) is better. It is
best to leave the mirror alone. The focusing screen can be cleaned with
canned air. Or a brush or even a cotton swab. Some of course are
removable/interchangeable making cleaning pretty easy.

I have used a mixture of ethylene alcohol and ether (50% + 50%) on a very
soft lense paper. Not rubbing, just tuching. Rather lot of the fluid.
It worked very fine on my surface mirrow, but I give no guarnties it will on
yours.
Compressed air doesn't not help if the mirrow id greasy. It only removes dry
dust..

Bye the way, the same mixture is perfect for cleaning lenses as long as you
don't get it inside the lens - the lens cement in coumpound lenses can be
demaged.
