Weekly wipe-downs and compressed-air sprays can rid only so much of the daily detritus and bacteria that build up on your keyboard. The Logitech K310 is built to withstand up to 11 inches of water, so you can give it a proper scrubbing. Drainage ports in the backside speed up drying, and its sturdy, laser-printed keys won't fade with the grime. [$40; logitech.com]
