I'm thanking my lucky stars so far, because I didn't have dust/grit on my D30 CCD and my D60 seems fine as well. The D30 has been sold, but both the D30 and D60 have been to the coast a couple times and our digital cameras obviously come with us on every outing...no matter how much dirt there might be.
I tend not to use compressed air on anything except the exterior of the camera... a little leery of blowing things deeper into the inner-workings of the camera.
Is the dust really noticable in the images, or is it something you primarily are noticing on visual inspection of the camera/CCD?
And, stupid question of the day... what in the world is a Pec-Pad? I have something entirely inappropriate in mind when I read that...
