Dust in unibody screen!

Anyone know of any fixes?

Would the apple store sort this out if I popped in? It's only a small black mark but it's definately behind the plastic front (seemingly appeared overnight)!

It definately looks like dust - it's near the bottom of the screen and so sits on the start bar (in windows), so quite annoying. This is my 3rd replacement - so really dont want to go through swapping it again!

Can these screens not be dissasembled easily then? If an apple store can open it up to clean it then that would probably be the ideal solution.
