Vacuum the dust from inside PC case?

April 14, 2010 at 15:17:45
Specs: N/A
Just wondering what your views are on people using a vacuum to clean the dust out. I myself feel that it might put out a static charge and possibly mess up a motherboard or some of the components.

I'm talking about the PC being totally disconnected and then using a vacuum inside to suck out all the dirt and dust bunnies.

Do you think it is safe to use a vacuum for that? I myself use compressed air for that.

I have a little Craftsman wet/dry vac with a small tool kit I use to blow dust out. The nozzle end of the hose is rigged with a 5 or 6 ft length of 12gu wire and alligator clip to ground the hose.

Air flows pretty fast thru the little nozzles and probably generates more static so I'm careful not to touch anything inside the case; grounded or not.

When anyone asks, I recommend canned air though. A vacuum can generate a lot of static from air scootin' through the hose and one touch could be all it takes to wreck something.

That sounds good, but you obviously don't vacuum off the motherboard.

I agree with that 200%

For boards, I have 2 brushes I use. One is a round ladies make up brush and the other a 1" paint brush. They seem to reach about everything and then I can blow it all over the room.

I just vacuum the inside of my PC last week. I also use brush for those hard to reach areas. Also a damped cloth to finish it up. So far all is well.

I take them out side and use an air compressor and a soft paint brush.

Not trying to compete with "Myth Busters" but tried a vac on an old clunker and never could get it to have a static discharge.
The vac or the clunker ....I don't know.

Good idea!

I have a small shop vac that's all plastic that I use. I always make sure I'm grounded to the case with one hand while vacuuming with the other. The hand holding the nozzle always has one finger in contact with the case while vacuuming. Even though plastic not conductive I still like to make sure I don't have any chance of a discharge.

I don't vacuum components, just the bottom of the case and then only if it's really dirty. After vacuuming, I'll use compressed air on components.

I've never had a problem or blown any components and I've been doing that for close to 15 years.

No, like I said, I used compressed air, then vacuum up the mess afterwards. By "the mess", I mean all the dust & crap that ends up on the bench & floor. And I don't use canned air, I have a small $25 Craftsman compressor that's generally used for footballs, basketballs, bicycle tires, etc.

There are times when I take the case outside, grab the 50' hose from the compressor in the garage & blast the hell out of it with 90 PSI air. If I do that, I just let the dust fall it where it may.

Yup, I've done similar, only I prefer to use a heavy duty leafblower with a funnel stem adapter ... very efficient & the job's done in less than a minute.

I too use a compressor but I live in a high humidity area, So I
have to be cautious of moisture buildup in the hose. A short
blast to clear the hose before blowing the parts.

I'll have to try that.

The leaf blower works great.I have a battery powered one. I also use it on TV's that I repair. Keeps all the dirt out doors.

The first time I dared to open a case was in 2000 to replace a 56k modem. I was afraid I would ruin everything. A guy at the shop where I bought the new modem told me not to use compressed air saying + chaged particles could land on - charged parts and cause a short. Being already overwhelmed by the idea of doing this myself I listened. I bought a small car vac with a long rubber hose and used it and a few detail brushes. Over time I moved to a larger house vac and fabricated some rubber tubing and a funnel like adapter. I use this about once a month, yeah I am anal about dust in my system, and have never had any issues. The worst is always the heatsink on the processor. For this I fabed a tiny crevis tool. Whatever dust that simply won't be sucked up I use my detail brushes and maybe some Q-Tips. The system I am on now I have fabed filters for all my intake fans to help but they have to be cleaned about once a week or they clog bad.

After using a vac for so long I feel it works just fine for me but so many are against it there must be problems so I will never suggest that someone else use one. Could be I am just lucky, who knows?
