This works really well, and you have loads of fun blasting people in the ears with it as well! I unplug my keyboard, tip it up on its side and bang gently on the desk, then either hoover or tip it upside down and grimace at the amount of Ryvita crumbs that fall out. Then wipe it with antibacterial wipes. The kids at school seem to be adept at prising off keyboard and laptop keys. Maybe ask them for some advice. Could do with a new one myself but rather attached to this one now.
