I saw a cleaning/dusting wand today. It's basically a stick with about
18 inches covered in soft wool. I've seen them on TV covered with some
kind of man-made material like nylon or polyester which I was thinking
might damage the finish of the piano over time. On TV the put the
stick into the hose of a vacuum for a few seconds and it creates
static electricity on the hairs of the wand. Then you lightly dust
objects. I'm wondering if this wand covered with wool would be okay or
is the nylon one safe to use on the high gloss finish.
Thanks, Mike
