Though this might not stop you from eating by your device(s), we encourage you to clean your keyboard regularly. Just take an old toothbrush, wash it with some soap, allow it to dry, and brush away any lingering remnants.
We suggest combining equal parts baking soda and vegetable oil to loosen and soften stubborn grime. Then apply the paste to your cabinet doors with a cloth, and remove the paste afterward with a clean, dampened cloth.
