I have (well, ok, my employer has and I use) a Dell Precision M6400 notebook. It's a decent piece of hardware, but I have at least one major gripe: It's a dust and...uh...crumb (I repent! I repent!) magnet! And I cannot seem to exorcise the dust/crumbs from it!

There is a strip of metal above the keyboard that is punched full of tiny holes. Well, maybe it's better to describe them as 'pits'. If a sufficiently small particle finds its way into one of those pits, there is only about a 50% that I will manage to get it out. Consequently, there is now a chorus of tiny little particles silently chiding me about eating cookies a cracker whilst I browse the intarwebs.

Does anyone have any suggestions about how I could remove these particles from this machine...while still preserving the function of the machine?
