Canned air is too expensive but it is the best. No humidity/moisture in the
electronics canned air, no static.
But I refurbish a lot of old PCs. So I went with a shop vacuum that can
reverse blow. I vacuum first to reduce the big dust balls, then reverse
blow the case OUTSIDE to remove the dust. I use an adapter that changes the
1/4 inch hose to 1/4 inch hole so it blows out real fast and strong. Cases,
power supplies, car interior where you can't reach, dust on indoor plant
leaves, etc. You can reduce the strength by increasing the distance from
the object to be "dusted".
I wrote an old google post on this vacuum a couple of years ago, lets see if
I can google search for it ...
Yes, I found it, here it is. I hope the links still work, otherwise search
the sites.
I have opened many PCs and those in offices and banks and large companies
are the worse for huge amounts of dust. And hospitals. You would think a
hospital with its constant cleaning and floor washing and dust moping would
be dust free but the dustballs inside are incredible. I guess the problem
is they sit there for 3-4-5 years running and no one ever opens them up.
Since I have to repair and refurbish PCs a lot, compressed air cans is too
expensive. I finally found a small shop vac type model that plugs into the
110v AC, is relatively portable, and can reverse the air flow. It does not
really reverse the air flow, you just remove the hose from the intake hole
to the outtake hole and it blows out.
So what I do is take the PC outside with the covers off (I have easy access
to the outside), vacuum (suck up) all the loose dust I can, then put an
adapter that restricts the hole to 1/4 inch or so (a nozzle), reverse the
air flow, and then blow out the PC everywhere. Every nook and cranny, all
the fans (CPU, case, power supply), open the floppy drive door. You should
see the dust that flies, it is so bad I have to go outside. I then spray
the dust away on the ground like a leaf blower. I have done hundreds of PCs
and other electronic equipment with this and have no problems blowing with
this method. The pressure of the compressed air is not that great but the
nozzle does concentrate it enough to give it power. It is not strong enough
to strip off jumpers or leads, nothing like that. I also use a 2 inch paint
brush to loosen really stuck on dust. As always, do it gently and carefully
to avoid any problems.
This vacuum is superb. Price is good too. It is the Stinger Shop Vac 2
gallon version, approx $30 US. I bought it from Home Depot, paid $49 Can in
Vancouver. But you have to get the attachment kit for $10 US or $15 Can.
This has the nozzle which concentrates the air pressure spray. Absolutely
superb. When blowing it has a filter so no noticeable amount of dirt
escapes into the exhaust air which is used for blowing as I was afraid this
would happen. I blow crap out of keyboards to. Superb. Just be careful as
you will be surprised how much dust it will blow out. And trust me, do it
outside.

Oh and it is useful in the house too. Got a vase of dried flowers or
similar items? Take them outside and blow the dust off with this vac. You
might want to try without the nozzle as it may damage the flowers. I have a
CD tower to hold 200 music CDs, a pain to dust, have to pull out the CDs one
by one and dust. Not with this. I leave them in place and just shoot air
in and around the CD case in the tower and it does a pretty good job in 3
minutes. My kids had a birthday party and I had to blow up balloons,
tiring, not with this. Finished in 5 minutes about 50 balloons. Air
mattress, real quick.
Damn, I sound like an infomercial ...
Note this is a useful tool for people who open PCs up a lot. For the
typical person with one PC, a can of air is probably cheaper. But you might
justify it for other uses around the house. If you can stand the sound, you
could point it at your CPU and cool it while overclocking.
