Xbox 360 + Spray Duster = ???

Anyone ever use those spray dusters like http://www.bestbuy.com/site/olspage.jsp?skuId=7997554&type=product&productCategoryId=cat08042&id=1155071451572

to remove dust inside your 360? I'm not sure if i have any but I'd like to clean it anyways. But will this work without causing damage to my console? And do i just stick the straw isnide the back vent and blow?

I though about that, maybe it would work for my old Xbox console?

aight cool, ill pick one up soon.

lol getting high on chemical that contains liquid nitrogen doesnt sound safe.
