I know there is another thread about this, but I need to ask specific questions. I was down at LHR the other day with my new Canon 100-400 lens. However, it seems that my 20D has a sensor that looks like someone has sneezed on it (I counted 35 dust spots). I am sure that all the dustspots I am getting on my images aren't down to the lenses I am using, as I keep them spotlessly clean - plus the 100-400 was straight out of the box.
I have been reading various sources on the web regarding cleaning the sensor yourself, and I have more or less decided what I am going to do (statically charged nylon art brush that is completely free of glue). I am wondering if anyone else on this forum has done any of this. I need the camera for the coming weekend, so sending it away for cleaning doesn't seem such a good idea.
Alternatively, does anyone know of a place I could get this done professionally in the Slough/West London area, if I don't have the balls to do it?

Just buy a packet of sensor swabs and go for it. It's not as delicate as you think. A few drops of eclipse fluid on the swab... swab to the left... swab to the right... and voilà: Clean sensor!
Did it 2 weeks ago and I managed to get it completely clean with one swab. On previous attempts (I cleaned my camera 5 or 6 times in 2 1/2 years) I often had to do it twice because not all the dirt was gone, but I guess I'm getting better at it.
Nothing to get worried about, it's quite easy.

Fixation based in Vauxhall clean your sensor for 25 notes and they do an amazing job too, 'while-u-wait'. Just keep your expensive DSLR in the bag while you walk the streets of this delightful part of London

Quoting LGW (Reply 2): Fixation based in Vauxhall clean your sensor for 25 notes
...and five minutes later your 100-400 will suck all the dust in 5 miles around back to the sensor
I would not pay for that, Andy, do it yourself as Eduard said (a good blower like the Giotto Rocket can suffice in an emergency). You can be sure you are going to use the cloning tool pretty often with your setup, just get used to it
"Be prepared to engage in constructive debate". Are YOU prepared?
Most of the gear can be purchased from warehouse express, however from the link above you can get a "Sensor Sweep", it is a very fine brush which you can charge the bristles(Statically) then when you use it you just hover it over the sensor and the dust particles are attracted to it. I got one from that site and only took about 4 days to arrive. This will only work on loose dust, stuck on dust bunnies will need the method Eduard suggested.
