you don't. that is my best advice.

Until you cant see to frame and focus, don`t. Then take it to a repairman.

My Dslr limited experience tells me a hand blower would probably be safe. No liguids, no cloth, no touch.

if i try to clean it with a micro fiber cloth will it hurt the mirror? is the mirror any thing special or its just glass? be cause i got impatient and cleaned it with a microfiber cloth

SLR mirrors are First Surface mirrors, meaning the reflective coating is on top of the glass. They are very easy to scratch. I know from experience from using a microfiber cloth to remove a fingerprint on a telescope mirror. After using the cloth, I noticed very very fine scratches -like a haze if you looked carefully with a bright light at an angle. You probably will not notice anything, but I wouldn't do this again.

The silvering on some mirrors is so delicate a blast of compressed air can damage the surface. Even with a Giottos Rocket Blower, which is easy to control, I'm very careful using it to dislodge dust.

If dust specks really bother you and a puff of air won't remove 'em, get a "riggers" brush used by watercolor painters. It'll have long (1" or longer), very soft fibers, thin with only a few fibers. The synthetic types are less likely than natural fibers to contain any residual oils that might be transferred to the mirror. Use the tip of the brush to very carefully dislodge and pick out specks. I use mine only to dislodge stubborn specks, not routinely.

LEX, thanks for the heads up on the "riggers" brush.

Look for the "Silverwhite" brand synthetic brush. If not available at Wal-mart or local arts and crafts stores, try Cheap Joe's online.

if the blower doesn't work, use Sensor Swabs and Eclipse fluid. The mirror is not as vulnerable as the sensor, but a good idea to clean them the same way.

Every now and then, especially after a long shoot, I begin to see noticeable specks when I look in my viewfinder - that's almost always "goop" on the mirror of my 1D2 and 1D3's from internal lube (or something?)

Louie Vincent Chua , Apr 18, 2008; 01:28 a.m.

is that safe? is made from plastic right? will it scratch the mirror? and are the sensor swabs safe as well? i know i could clean the sensor just making sure
