Save Your Keyboard

The main reason that most computer keyboards fail (other than letting my son get near it) is the gunk that accumulates in the base below the keys.  I have tried many ways of getting this stuff out because I want the keyboard to last as long as possible (why should I pay for a new keyboard every few years?).  I have tried pieces of paper, cans of air, and q-tips but nothing has worked better for me than a few post-it notes.  All you have to do is fold the sticky part of the note in half and push it between the keys.  You should then be able to slide the note the length of the keyboard.  This will allow you to get that entire row clean.  Repeat for the other sections of keys and you can keep your keyboard running longer than your computer.
