Mostly I just pick it up and shake it upside down. For some reason there are always crumbs in there. Can't imagine why, though maybe it's the morning toast, or other snacks I eat over it? When I worked mine was always full of dust and crumbs. I use a paper clip to pull out the dust bunniettes in there. Used to be able to pop out the keys and clean under them for the worst mess. Now and then I use the vacuum on it. Got one of those sets with tiny heads to put on your vacuum for keyboard and sewing machine, but rarely bother to pull them out and use them. I've heard that canned air meant to blow dirt out might actually force it into smaller crevices, so not a good idea. Hey, Ranger, I like your signature line!
