How to clean keyboard?

What is your openion?
How you guys clean your keyboard?

1. Disconnect the keyboard from your computer.
2. Turn the keyboard upside down and over a trash can and gently shake the keyboard to remove dirt from between the keys. It is ok to give the keyboard a few slaps on its back side to jar loose any foreign material inside. Also, you can give it a few short blasts of compressed air to help remove debris.
3. Next, moisten a cue tip with alcohol and gently clean between the keys. Or, you can moisten a soft cloth with a gentle cleaning agent to clean between the keys if you like.
4. Reconnect the dry keyboard.

Well thanks Mason for the guidance! :)
