Retractable Keyboard Brush and Keycap Puller
The large brush is the tool you will use most. Push the button and it pops out of the housing, ready to sweep crumbs and dust from between keys; push it back and the bristles are protected. It works with the keyboard still connected and the computer running, which makes a quick clean after lunch at the desk easy, and cleaning effectiveness is the most praised part of the kit, with keyboards looking practically new afterwards. One owner cleaned a mechanical keyboard and found the brush lifted every piece of dust. For a deeper clean on mechanical and gaming keyboards, the keycap puller lifts keys off so you can clear the plate underneath. A second, smaller high-density brush reaches between the flatter keys of a laptop, where the big brush is too broad.
