Time is precious and I dont really want to spend time trekking to the Canon service center and then waiting 30 mins for the CMOS of my DSLR to be cleaned.
I read in the manual that I shouldn't attempt to clean it myself and every time I opened the shutter to blow dust away from the CMOS I would break out in a sweat knowing how delicate the sensor was. Usually a blower does the job but eventually you'll end up with some scum dust on the sensor that just does not want to go anywhere. Leaving the dust there means that you will get blobs on your photos. Have a look at this photo - notice the annoying blob in the sky.
I searched to see if there was a way for me to clean the CMOS myself and chanced upon two sites - one in English and the other in Japanese. The Japanese blog advised to get some lens cleaning paper, cleaning liquid and sharp cleaning buds which I got from HCL - folks in Japan can order directly from them.
CMOS Cleaning (click to enlarge)
Cut some of the cardboard from the lens cleaning liquid package and then wrapped some of the cleaning paper around it. Gave the paper a few drops of cleaning liquid and took a deep breath. Too little liquid and you may scratch the surface of the CMOS. Too much liquid and you may leave liquid marks on the sensor which will show up in your photos.

Make sure you have good lighting before you start and proceed to wipe the sensor. Not easy but you'll feel satisfied after when you manage to pull this off. When the sensor looks clean, take a picture of a monotone surface - and make sure the picture is in focus. You should check the photo on a computer screen as its difficult to spot blobs on the SLR built in LCD. You'll probably have to repeat this process a few times.
CMOS Cleaning (click to enlarge)
There are many ways that dust gets into the chamber where the CMOS is. To decrease the chance of dust getting on the sensor, make sure the lens and lens attachment parts are clean. For this I use some of those pointy buds dipped in cleaning liquid. Not sure how to prevent mechanical dust though.

Taken before cleaning. Adjusted the curves in Fireworks so that you can see how bad the situation was. Whenever I have a photo session, I would always take a picture of the sky to check for blobs.

If you are going to clean the CMOS yourself, please do so at your own risk! I would say that if you can make Gundam models then you are good with your hands (oo er) so you'll probably be able to pull this off - but then again, you decide ^^;

I know what you mean...don't really have a lens camera myself but I hate it when stuff lands on the lenses of my digital camera making some kind of weird figure when taking a quick group photo or what not

xjaymanx in vegas, baby!
looks like u managed well!... i'd definitely hesitate with my 350D... but in this light, the 3-step anti-dust technology ("EOS Integrated Cleaning System": anti-static materials, ultrasonic vibration, and software removal) in the 400D (a.k.a. Rebel XTi) looks more and more appealing!... but understandably more expensive :)
(ID #42326) Posted on 2007/01/02 01:23
I probably should do this sometime in the future as well. ^^ May I ask how often should one do this?

Ohh! The new Canon Digital Rebel has a feature that removes the  dust on the CMOS... but will your problem be corrected with this new feature?

Ohh another question, did you try those  compressed spray cans? They do a pretty good job at blowing dusts away.

"Make sure you have good lighting"

Yes, but you gotta make sure your sensor is not exposed for too long under strong light...

You got your CMOS cleaning done :)

I try to prevent dust from entering by pointing the 400D down on the floor and attaching the lens. 

Hope mine doesn't have much dust :)

Man, I'll never clean the CMOS myself, considering how one of my friend actually damaged his EOS1D because of that.

I just buy a new SLR Canon 30D, and after 2 weeks, i notice some little blotch. Not really dust, but maybe humidity. I just buy a 3M microfiber tissue. Now it's Ok, but it took me more than 1 hour to clean and check after each passing. So, I will buy Eclipse et PecPad, (+ a sensorsweep for fast outdoor cleaning).

A rather risky job indeed and I know I will eventually have to clean my 400D at some point, but not now since currently I keep it very clean. And the automatic cleaning feature does help.

Funny that you mention this. Today I just took 400 pictures on my old Nikon D100 and... there were five or six big splotches of dirt on every picture. Cue 2 hours of i ntense photoshop work.

But I would probably never clean it myself. I'll just bring it down to the service centre, considering how small Singapore is.

I'm a little slow lately; I'm trying to help with some last minute shopping.  Anyway, thanks for the link on Canon Service Centers.  I had been trying to find the one in Osaka.

Enjoy your weekend!  I guess you will be heading over to World hobby Festival.  Looking forward to your post.
