I read that you could clean your keyboard by washing it in a dishwasher. My son's keyboard was filthy, so I decided to try it. It came out beautiful, and even worked for a while. Then, it stopped working. The caps light comes on after powering up the computer, but that's it. Now I have a mostly dead keyboard. Maybe I should try washing it again.
In any case, word to the wise - don't wash your keyboard! I suspect that minerals from the water might be causing trouble. Regardless if it is minerals that is causing the problem, I'm out a keyboard.
