Cleaning a keyboard...

The least bothersome way -

Use a dilute, non-abrasive, preferrably volatile, cleaning fluid. Most of the ppl recommend using isopropyl alcohol. Dip a soft, lint free cloth in it and wipe around the keys. (NOTE - Avoid spraying the liquid on the keyboard directly... you might end up short-circuiting the keyboard.)

The EXTENSIVE way -

1. Unplug the keyboard from its port.

2. Pry off all the keys from the keyboard.
NOTE - First make sure that you remember the exact location of the different keys.

3. Open the keyboard by unfastening the screws at the back. Take the electronic circuit out. Also take out the rubber membrane.

4. Wash the keys, the main keyboard frame and the rubber membrane. You can use warm soap water to do that.

5. Dry all the components separately. Do that for at least 24 hrs. This is to make sure that you do not leave any water droplets on the electronic circuit, otherwise, once again, you might short-circuit the electronic circuit inside the keyboard.

6. Put together the different keyboard components - the membrane, circuit, keys...

Dude, could it have been more comprehensive??? :)

NOTE -

(a) I would strongly recommend NOT using the EXTENSIVE way to clean the keyboard, if it is a wireless unit.

(b) Some ppl also say that you can directly wash the keyboard in running water / soap solution, without having to open up the unit and take out the electronic circuit present in it. In that case, just be doubly sure that you haven't left ANY water droplets inside the keyboard.
