Found a brand new in box HP keyboard in an old (almost empty) pc computer box in the garage. Plugged it in and then took my ole dirty one and ran it under the shower, shook it and tapped it to get the water out - dried - and now it's working fine lol. It was nasty dirty - spilled food, coffee, you name it. Now I have a spare.

Ever try to pop the keys off and then clean it? Take a pic of it first, w/ the keys on.
