For daily dusting, I just use a swiffer or my Billy Bags Audio Duster. Not to sound cliche, but both do attract dust like a magnet. Every few months, I use Endust for Electronics (sprayed on a cloth diaper) on the front panels of my receiver and amps, and the top, bottom, and sides of the non-ventilated stuff. I never touch my equipment though, so most of the time it is unnecessary. I also use Pro Gold once a year.
