Greetings, T'other day I got a little duster at the grocery store for a buck. Twirl the handle between your palms to electrostatically charge the mop. Looks like a critter from Dr. Seuss. Works like a charm for getting dust off the tools hanging on the wall, between the bars of a Ledu lamp, and other little nooks and crannies that are a pain to dust or vacuum. (Hey, gotta have something to do while the brads dry.)
While I'm at it, I'll mention a little round basting brush I found in the cookware section of the same grocery store. It looks just like the $4.50 detailing brush in the GarrettWade catalog (minus the cup hook), but it's $1.39. Works great for getting dust and fine shavings out of a plane--you know, that dust trap around the frog adjusting screw.
