I clean the dust off my speakers and all my electronics frequently (atleast 2 times a week). All I use is a dry cloth that came with my LCD t.v. I just run the cloth over the surface with very little pressure to pick up the dust. The only time I use a damp cloth is when I clean my television screen, then going over it again with a dry cloth.

I’m armed and I’m drinking. You don’t want to listen to advice from me, amigo.
