How do I clean my Laptop's airvents?

Hi all, I would like to know how do I clean my Laptop's airvents? I dont want to spray air in the vent because I am afraid that the dust/stuff might go inside my laptop, any help would be great, thanks in advance.

They make small specialized  car vacuums these days, (also  tiny little vaccums for keyboards..) make sure its a rubber attachment or or brush attachment touching your notebook if you can. Any small vacuum is all I can think of.

here's one example on a "google" search

Not to promote another forum, but I found this guide quite useful.
Hope this helps.

I personally see no problem with this approach...some Forums are very specialised indeed.
