Thanks for the link Anthony! Since yesterday I collect info from internet how to do clean a camera myself. I am so affraid of it to do it. I am not good with fine delicate job.

I did called Canon back, they totaly rejecting my arguement. Kinda, like it or leave it attitude they have. The sensor not faulty. They can not clean it without damaging a sensor (some particles so much stucked to the sensor...(??) so they not do it so. Sound like to me they did not even try it at all.  I even got an advise if I am not happy next time buy a Nikon!! Not bad Canon!!
