How do you clean/dust off the inside of your computer case and the hardware?

Just want to know some of the ways people do it or if they even bother at all. I have a friend who uses an air pump to blow the dust off.How do you clean/dust off the inside of your computer case and the hardware?
The compressed can of air works great. It can be found at any Wal Mart or computer store. Of course, Wal Mart will offer the best price-as far as I am concerned, air is air and no single brand would be worth any more than any other. This should be all you need to do to clean out the cobwebs and dust.How do you clean/dust off the inside of your computer case and the hardware?
A can of ';compressed air'; is commonly used.
Ouch he is pumping water in to the contacts. you should use dry air or a lint free cloth. those air pumps don't get all the water out of the atmosphere.
you can buy a small vaccum pump at cdrking which costs a little more than PHP100.00.... this one's light duty only... so take care of it...
In the past, I've taken the computer out to the garage, removed the case, and used canned air to just blow the dust out of everything. I'm careful not to invert the can, since it seems to shoot out a liquidly kind of substance. It's a good idea to keep the dust out, since it gets hot in there, and can cause damage if too much dust builds up.
Compressed air can
A compressed air can is best.





Who cares who dares?
Compressed air (canned or otherwise) is best, though you can use a soft brush, too.





If dust builds up, it can block output vents, or fans and cause the machine to overheat.
Normal systems are opened up, after powering down, and the fans and heat sinks are removed to a kitchen sink, rinsed out, and allowed to dry.





I apply new dielectric paste, and reinstall.





Really grungie systems from people who smoke get turned away.





Cheaper to just buy a new system, as nicotine coating is sticky and bogs down all the fan bearings.





Coating also overheats all components, and glues in the connections, cables, memory sticks.





Used to pressure wash them, but, that can lift surface mounted components when you use 1500 psi that is needed to lift off the nicotine residue...





Now, on systems that are infested with cockroaches, we fumigate, then toss out the PSU, and install roach motels, after a good rinse to clean out all the droppings and feces.





Simple air doesn't always work. We had one unit that was home to Norway Rats...
