That is a very good point, and it is also possible to damage the shutter curtains (an even bigger problem) and possible even the sensor itself (didaster)
On the 10D, it wont let you enter cleaning mode unless you have a fully charged battery.

I use these; they are excellent if a little costly. They are custom made for each sensor type/size/make

Of course using these is at your own risk. I was shown the proper method by a pro camera technician, it is however a very nerve-racking experience the first time, and requires a steady hand.

To be honest I leave it alone until it gets quite visible, for me once or twice a year seems to be ok.

The sensor dust issue is well documented and IMO it is something you either have to accept or choose another type of camera
