Falcon Dust Off Professional is an excellent product for removing dust from high tech gadgets and computer equipment. It comes in a 12 oz can with a spray top which also has a thin red tube to help direct the air spray to the area you want to dust.
This dust remover also contains a bitterant to help to discourage inhalant abuse. I used Dust Off Professional to clean both my desktop and laptop computers. It performed beautifully on both computers emitting a wide spray with no liquid, which cleaned my keyboards on both computers as well as the inside of the cpu of my desktop compter.
It is important to keep computers dust free and clean to ensure they continue to run properly. Falcon Dust Off Professional is an excellent duster for this purpose.
