After trying it out, I found out that it sucks. Or rather, it doesn't suck. Er... It fails to remove the aforementioned schmutz. This came as little surprise to me, since there's obviously an upper limit to the volume of air you can move with a pair of AA batteries. But I suddenly became curious as to whether an effective "keyboard vac" exists at all. So I thought I'd ask here: Has anyone encountered an effective, small hand-held vacuum that doesn't suck? ...er, does suck? Sucks well? Whatever..."
