There have been many tutorials as to how and why to periodically clean your keyboard. I've tried them all. This is the method I found most effective.
1. Inform you family/friends that you will require their assistance.
2. Visit the site of your choice. Make sure, (and this is a critical step), that it is of vital importance to you.
3. Eliciting the aid of your helpers, have them bug the crap out of you until your blood pressure reaches no less than 260/180
4. Firmly grasp the edges of your keyboard.
5. Now fling it towards the nearest hard object you can see.
6. Have someone fetch you a broom and dustpan while you calm down.
7. Sweep up the pieces.
8. Empty pieces into collander and shake out debris.
9. Tell helpers to get lost while you reassemble to avoid repeating steps 4 - 8.
