Recently, I've had a number of dustspots appear on my shots, regardless of the lens I use - moreover, they're always in the same position in the shot. Since I've carefully cleaned everything else, I presume the camera sensor is dirty (I have a 20D).
I know of the "Sensor Clean" function that allows access to the sensor for cleaning. Now, I wonder what's the best way to clean it? I haven't tried anything yet, so I'm asking you guys/gals for suggestions. I've heard/read somewhere that one method is to squirt some air over the sensor with one of those small clear plastic pumps (lost for proper translation, those like ordinary plastic droppers)...

I also recommend the copper hill. May take a whole 3-5 minutes to do, from reaching for the pouch to putting it away again. That could possibly be too much for those with the attention span of a humming bird. However it work's perfectly, and gets your CCD spotless. but in the end its up to you, gentle pec pads or highly compressed canned air blasting through the insides of your camera

Quoting JakTrax (Reply 4): DON'T use compressed air - it can damage your sensor! Instead invest in a Giotti 'Rocket Blower', which is powerful enough to remove even stubborn dust without harming your kit.
How in the world will blowing air be more likely to damage your sensor than something physically touching it?

Thanks for the answers everybody. A minor (sometimes) problem in my case is acquiring these products quickly enough, since goods from abroad sometimes take their sweet time in getting here . I will look into all of these you mentioned, especially the DustOff JeffM mentioned, sounds good.
In the mean time, I presume the licenced "service station" is the safest choice.

Before you go touching the sensor you should try a blower first. Loose dust will easily come off with a couple puffs. If that doesn't work, then it's time to break out the PEC pads.
I would avoid canned air as it can push dust into gaps around your metering sensor, TTL sensor, prism, etc. The camera store I use has had several cameras come back with dust between the low-pass filter and the sensor, which requires a visit to the service shop to repair. The only explanation they got from the manufacturers was that high pressure air caused the problem. To each their own though - done carefully I'm sure it's quite safe, I'm just not willing to risk it.

What a bunch of crapola....
Really? Then may I suggest you read your camera manual, which will clearly tell you that compressed air CAN damage your sensor. I know this is more-than-likely just an exit clause for the manufacturer should something happen but if it says 'DON'T' in the manual I'm certainly not going to try it just to prove a point.
In addition, I've read about canned air being bad in several photography magazines.

Some brands can, others won't. It's the propellent and additives that cause problems. I use only one brand that has been tested and used by many camera stores. Dust-Off. I mentioned that brand in my post. I did not say 'use any canned air'. You can read all you want, I'm talking actual experience over almost three years and three different DSLR bodies.
