Instead of using swiffer wipes/pads specifically for cleaning speakers and electronics, I've found that re-using anti-static softener sheets from loads of laundry works great, as well. Instead of tossing those used dryer sheets, save them and use them for dusting purposes. They retain a moderate amount of anti-static capabilities and they're soft enough not to damage any precious finishes. Plus, it makes you feel all warm and fuzzy knowing that you're getting some additional use out of a product that you'd otherwise just toss in the trash.
