I use "Century" Duster, Air-in-a-can. In the electronic industry (manufacturing and repair) we always used compressed air, or some kind of caned air. You will find the Office Depot Brand 10.0 Oz for $6.99 @ http://www.officedepot.com/a/products/911220/Office-Depot-Brand-Cleaning-Duster-10/ Or pick one up at your local Office Depot, Fry's or other electronic specialty store. I've use compressed air on my 1999 PowerMac G4 AGP Graphics for 11 years and no problems to date. Yeah it's old but works just fine. Preventive maintenance dust out about every six (6) months.
