A rubber blower works the best for me. I'm afraid to try to clean
the sensor. Once you screw up the sensor dirt, it's hard to get it
clean again.

I can certainly understand your reluctance to touch the sensor
after your experience, but it is really quite easy, just make sure
your battery is fully charged.
I recently did the spatula/pecpad/eclipse cleaning after putting it
off for a long time. I had about 30 spots. I also apparently had
some lubricant from another part of the camera. I dropped my 10d
in London and had what appeared to be a sensor scratch. It was
strangely shaped and had a prismatic affect on light. Could not
blow it off using my rocket. Was certain it was a scratch.
Cut and sanded down a spatula that I had in my kitchen. Put a
pecpad on it. Secured the pecpad with an elastic ponytail holder.
Put on eclipse and wiped. Repeat that 3x and down to a few very
minor dust spots. Best part is the "scratch" came off, so my
theorey is that it was lubricant from somewhere else.
Contemplated and planned for hours, completed in 5 minutes.
