It can be one of the most annoying things in the world. And it can happen to the newest and shiniest of laptops or computers.
Crumps, hair, teeny tiny bits of paper; they all seem to land right in the fiddly bits of your keyboard and it's a nightmare trying to get them out.
But, if you hate the sight of it, This Morning had a handy man on the show today, giving you a life hack on how to clean your keyboard.
Steve Wilson, life hack expert, simply used a Post-it note to clean up a keyboard. The paper's sticky side is perfect for wedging in between the keys and digging out whatever is in there.
It's such a handy idea, we're actually surprised we never thought of this before.
