How do people dust their systems?

I don't do anything sexy -- just a piece of terry cloth that has been VERY slightly dampened with water.

This may sound dumb, but I always wondered if there was anything wrong with vaccuuming the equipment?

I generally view dust as a form of equipment dampening -- resonance control, dirt cheap. :)

You mean you're supposed to dust this stuff???

Only if you don't use a vaccuum!
I use a product called "Grab-it" it is a finely woven paper cloth that I tame down with my Zero-stat gun.

Interesting - maybe I do have a problem! Anyway, I use a feather duster, if I add a new item I pick everything up while I'm back there and "lemon pledge" the rack itself.
I don't add things often.
