Dust under the screen...ways to remove it?

I just got my TI2 back from Access after they fixed the crooked screen which was great. Unfortunately there is now a big speck of dust on the screen. Is there some way to remove that using canned air or something? I can't believe I'd be the first person to have to remove dust from off of the LCD screen. I did a search here, but couldn't find anything relevant. Kemper gave me great Customer Service in fixing the cookedness, so I don't want to sound ungrateful, but I'd just like a clean screen.

Nevermind, turned out to be an easy do-it-yourself project. I just opened up, removed the daughter board and that exposed the plastic in front of the screeen.
