There are a number of sites on the Web dealing with sensor cleaning;
I'd expect Google can find them for you.

Visible Dust - http://www.visibledust.ca/ - gets good reviews, so
I recently bought a pack of their cleaning swabs and some cleaning
fluid. It did a great job on crud that a simple blower couldn't budge.
If you're looking for a simple solution, these, or similar products,
will do the job.

There are also do-it-yourself versions which cost less and should
also work nicely if you don't mind assembling the swabs yourself and
being very careful not to get any contaminants (such as fingerprints)
on them while you're working.

BTW, CMOS vs. CCD doesn't matter; you're not actually cleaning the
sensor. You're cleaning an assembly in front of the sensor which
filters out infrared and implements a low-pass filter to reduce the
incidence of Moire patterns. It's certainly not indestructible, so
you have to be careful, but you're not actually wiping a computer chip
or anything.

I've always had good luck with PecPads and Eclipse. Takes awhile to get the
knack of it, but after a few tries you can do a good cleaning on the first
try. The video is a bit misleading, as most people wet the swab, sweep in
one direction, move the swab down without lifting it then sweep back the
other direction.

Never had good luck with brushes, but haven't tried those new spinning
brushes.

Here is one other site which provides some useful dust control tools.

Use thew blower first, and get the whole mirror box lockup up and not
then use a soft brush given a static charge with canned air, I used a
cheap makeup brush but you can get specialized ones. Cleaning fluids
before this blowing and brushing will just push the dust around wasting
pads.
