When the mirror is locked up and you are looking in at the sensor on a Canon 10D, which part of the sensor would correspond to the lower-left corner on a photo? I'm guessing upper-left, but I'm probably wrong.

Thank you very much kind sir.

There's a small group of spots in that corner that don't want to come off with Eclipse. I'll get my gasket scraper out and get to work on that corner right away. I might even need some steel wool. :)

I find the detail attachment on my finish sander to help tremendously. ;-)

Has anybody used a SpeckGrabber to try and remove stubborn sensor deposits?

I saw these when I was looking around for Eclipse. It looks like a cool product. I thought about getting one, but I figured Iâ��d better learn how to use the Eclipse & Pec-Pad method first. Now that Iâ��ve gone through about a dozen pads, Iâ��m about ready to try Danâ��s finish sander idea. These things just do not want to come off!

It's basically a pure methanol solution. Check out these search results which talk about it.

I have the Speckgrabber, it's nice for when I don't feel like wasting a pecpad on 1 speck of dust. It works pretty well--worth the investment, certainly.

And Eclipse is a miracle product. Adorama will ship it.

It's a cleaning fluid. You can get Eclipse at Adorama for $7.50.

See this article for instructions on cleaning your sensor.

Is it possible to have burned out pixels on a 10D CMOS sensor? If so, what would they look like?

There is a group of 11 spots in the corner of my cameraâ��s sensor that I haven't been able to remove, even after cleaning several times with Eclipse and Pec-Pads. In my test photos these spots appear to be very uniform in size, quite round, dark in the center, with a light colored ring around the edges. When I first started cleaning the sensor I had a few other dust particles that I was able to remove quite easily. Those showed up as fuzzy, dark, irregular shapes.

Iâ��ve heard that some specks can be very stubborn and hard to remove, but this is ridiculous. Has anyone ever had specks on their sensor that were really hard to get off? How did you eventually get them off?

If these are burned out pixels, what can I do about it? Would it be covered by Canon's warranty?

The thing about bad pixels I find might be true. When use a longer exposure time, I get a tiny green spot around the center of my images,about 1 pixel plus a small amount of feathering. I'm considering taking it in for a warranty repair.

I used the instructions for cleaning my camera and it did wonders! I am so pleased. I sent it off to get cleaned and it came back worse. Much worse... but they did fix the back focus problem. Rather than send it in I put the dogs in their cages, gritted my teeth, held my breath and repeated the procedure about 4 times. Now, no more specks!

i am really suprised there aren't more threads on dpc about sensor cleaning. there are so many on other aspects of dslrs, but very little on cleaning.

then again maybe most people haven't had their camera long enough to start having a problem.

Very cool, I'm glad it worked out for you. I wish it was working as well for me. I've used up a lot of Pec-Pads and Eclipse trying to clean mine, but there's a bunch of little round spots that won't go away. It can't just be dust either because there's no way that I missed wiping them numerous times. I'm beginning to think they must be defects, either in the high-pass filter or the sensor itself. I'm bummed! :(

If they are that "stuck", the best thing to do is to let Canon deal with them if you are within the 1 year warranty period. Document them well and make sure Canon service knows you won't accept them. You certainly should not have to.

I noticed a few dust spots in some of my photos after only a few weeks of use. Iâ��ve had my camera for several months now, and I finally decided it was time to clean it. The first couple of wipes removed most of the stuff, but there are some that I havenâ��t even been able to budge. I may have to send it in to Canon for repair.
