Cleansing Hardware Of Dead Pig Odors? 693
Chagatai writes "My company is one of America's largest beef and pork producers. Recently I took a trip to see a new computer room that had been built at one of our abbatoirs. While the new environment is nice and sanitary, the old computer room had air intakes that were adjacent to the rendering portion of the plant, and everything smells in an almost unholy way. Management is curious if there are any cleaning agents or means of deodorizing this equipment before moving it into the nice, new office. The only products I could find would clean the outside of the hardware, but the internals would still possess the lovely aroma of boiled dead pig parts. Of course, this is a race against time, as I am sure someone will inevitably squirt Pine-Sol into the system to try to make things better. Does anyone have any recommendations to remove the effluvium of post-mortem porcine matter from our machines?"

Back in the early 90s, my dad bought me My First Computer. It was an Macintosh IIcx which was a big, beige rectangle box. Had neat stuff like NuBus and about 12 SIMM slots. I lived in Europe at the time, and the computer was purchased from a graphic design house where *EVERYONE* chain-smoked at their desks. The machine had the most disgusting tar-like filth on *EVERYTHING* inside the chassis. The upstairs of my house reeked of cigarettes.
I literally chipped away tar, vacuumed it, put Bounce sheets over the power supply fan, to no avail. The machine still sits in my closet to this day, and having given it my best efforts over 10 years ago- it still smells of stale cigarettes.
Because of the small nooks and openings in your average computer, I honestly don't think you'll be able to do much about the smell. Unless there are some new commercial/industrial agents that can do the job, you might be SOL. Guess it's time for 3M to create a solvent version of Fluorinert [google.com].

I worked in a large surface mount production facility. In the final stage of assembly, they would in fact go through a fancy dishwasher. Early on we didn't even use deionized water. They did switch to deionized water not so much for the fear of conductivity, but to not leave spots behind.
You want to put tape (waterproof - packing tape might work) over any speakers, piezo devices, potentiometers, dip/pushbutton switches. Remove any batteries and button cells.
Then stick it in the diswasher, I'd use electrasol. Also, skip the "drying" cycle and let it air dry. Where I live (Utah) the air is quite dry. It would be ideal to let it sit for a day in the summer sun. Then you are good to go.
If you are not blessed with dry air but humid air, it may take more than a day to safely dry before you can plug it in.
Under no conditions would I do this to vintage equipment, esp. tube equipment or even vintage transistor equipment. Old equipment will tend to crumble under the stress as old capacitors like to die (if they haven't already - google/get an ESR meter) and plastic will tend to crack. I would only do this for equipment from the mid eighties on. Before this time I would be judicious with the cleaning process. Like maybe not using hot water.
Modern components however are made to face a dishwasher, and can withstand it nicely, unless the components are defective to begin with (like some bad electrolytics on motherboards).
Only Solution - Activated Charcoal (Score:4, Interesting)
The only solution is to get those organic molecules out of the materials and that is not going to be easy. Here are the things I would try:
1) Heat. This increases the diffusion rate of the offending molecules from the plastics. Make sure you vent the oven to get the organic vapor out or they will just re-absorb as the unit cools.
2) Activated Carbon. Activated carbon has a great affinity for organic molecules. You may want to put each PC in a cloth bag and bury it in activated carbon for a while. Test with one first to make sure the carbon fines don't short-circuit anyhting. Get activated carbon from a scientific supply.
3) Heat and Charcoal - probably the best solution would be a conmbination of the two above solutions. I would put each PC in a cloth bag and bury the bag in a bed of activated charcoal. Bake everything on low heat for several hours (120 - 150 F). Use just a warm oven because high heat reduces the effectiveness of the activated charcoal. You can re-charge activated charcoal between uses by heating it at 350-400 F in the oven to drive the organics out of it. That will stink.

So let me tell you what did where I was working several years back. I was working with the FBI, on a special mission in Russia to help their law enforcement agencies upgrade security in former nuclear weapons facilities. Now, it wouldn't surprise anyone to hear that a certain facility that will remain unnamed, somewhere in the middle of Siberia, only a day or two's drive from a certain site of civil war, had an incident that wasn't properly cleaned up. We arrived at the main computer lab to find a dozen corpses that had been there for a year and a half. And despite the Siberain weather that can freeze spit before it hits the ground, the bodies in the bunker hadn't been frozen.
After getting a couple new gas masks for the guys that really should've skipped lunch before going down there, we discovered that the computers were overrun with, well, you don't want to know. Let's just say it was fuzzy and came in colors I'd never seen before. Even after the room was disinfected nobody could stand to go down there without a mask. Though one of the Russians suggested using it as a gas chamber to execute criminals, until we briefed him on the Geneva Convention. But we couldn't just throw the machines away-they included supercomputers and large clusters full of nuclear weapons research. The science team had to go through all of it with a fine-toothed comb.
So what did we do? Simple-seal everything off! We too a bunch of plastic covers and created an airtight seal around all the computers, with only monitors, keyboards, and mice outside. A ventilation system pumped cold air into the huge computer tent. It was ugly as hell, but worked quite effectively.
So, if your offices don't mind having interior decorating issues, a bunch of strong plastic, industrial glue, and lots of duct tape can solve the problem. Until somebody want to upgrade or do maintenance, of course. God help that poor bastard.

Power down all your machines and unplug them. Set up adequate ventilation (I use several cheap desk fans). Wipe down your hardware with rubbing alcohol using a lint-free cloth or a few old t-shirts; don't worry about your own, buy a big bag of them at Goodwill.
When you get tired of that, or you pass out from the fumes, just pour it in. Yes, I'm serious, you'll want to trickle it over the green hardware and get everything generally soaking. (Not the power supply or hard drive, just PCBs and the like. This is already a dumbass idea, so you don't want to be much more stupid about it.) Then leave, otherwise you'll probably pass out.
I discovered this trick while given the task of cleaning a friend's laptop. He smokes, a lot, and had quit and didn't want the smell. He also had sticky keys from God knows what, so I honestly just said "fuck it" and turned the laptop on its side, open, and poured rubbing alcohol into the ports, taking care not to let it get near the screen, which rubbing alcohol can damage. Using a lot of it allows the liquid to remove dust as it flows by. The excess flowed out the other side and into a few paper towels.
Rubbing alcohol is a great solvent and evaporates quickly, so the ventilation is more for the computers, not you. Make sure the insides are aired out before powering up, or you may find yourself battling a quick-burning alcohol fire.

I second Capt Nitro here, rubbing alcohol is one of the safest and most effective things you can clean electronics and computers with (Relatively speaking, like he said, there's obviously risks of damage to certain types of components, especially if it manages to pool somewhere where it can't evaporate away realitvely quickly - pull cases open everywhere you can, rotate the equipment around to get excess out, and use lots of fans).
Be *very* careful about the fire hazards. If you manage to somehow ignite the alcohol, things can get ugly quick, as the flames are often almost completely clear with the pure stuff, and you figure it out by burning yourself. Things get really nasty when there is a fire quickly spreading around the room and through the fumes in the air around you, and you don't even realize it and can't see how far it has already spread. If, at some point in this comical adventure, you find yourself sitting in the middle of a room full of fans, computers dripping in alcohol, and heavy fumes, and you even *suspect* that some of the alcohol has just ignited - GET OUT, and call the fire department or hose the room down or something.

But as for doing this job inside, NO WAY! . Not unless you have access to a fume hood. The LAST thing you want to do is poison yourself with the fumes. You're far better of to do it somewhere outside, and a few metres away from anything flamable and even further from anything that generates sparks I'd even suggest doing it after dusk. That way, if you do manage to light the stuff on fire, you'll have some hope of noticing it before you have 3rd degree burns over vast parts of your body.
For safety, I'd suggest having a workmate standing by with a water hose (and a sprayer with a hand-trigger that lets you have the tap turned on for fast response).. uphill and upwind if at all possible.

This rubbing alcohol isn't more toxic than 70% ethanol, and some alcoholics actually drink it mixing it with sweet juices/sodas! (Yuck!)
The third type is isopropyl alcohol, used in many other countries, including the U.S. In moderate amounts it is not toxic (of course if drink a lot it will harm you, but also too much ethanol will kill you). It is used because it has the same disinfectant properties as Ethanol, but it smells and tastes nasty so people don't feel compelled to drink it. If I'm not wrong, it doesn't get you drunk so there is no point on trying it (and that is the reason it is favored over the ethanol rubbing alcohol).

Soak in ethyl alcohol to loosen clotted material (in my case, literally.. again, don't ask) enough to brush/wipe most of it off. Immerse in electronics cleaner in ultrasonic bath on low. Board comes looking almost brand new. Allow to dry under a fan for several ours. Test, and reinstall.
Replace all fans and filters if possible (easier than cleaning the damn things). Reassemble. Before closing the case, hang a couple of those pine-tree shaped air fresheners in the case.
There are also a lot of forensic clean-up information websites out there.. Google is your friend. Hope this helps..

Most of the parts ended up well-cleaned and generally stink free. Unfortunately, the power supply was uncleanable without a total dissasembly that would have rendered it unusable, and the while the case appeared clean, once it warmed up it stank just as bad as before; as far as I can tell it was just some weird feature of the paint that kept me from getting the stink out.
Since I couldn't fit an Antec server case in the dishwasher, I wrote it off as a loss, tossed it out, put the parts in a new case, and donated it to my college-student sister.
Ozone (Score:5, Interesting)
Things you can't clean by washing can be put in a tent with an ozone (O3) generator. Ozone is what you smell after a lightning storm: the clean rain smell. Concentrated, it smells sort of like bleach, but sharper.
It's both toxic and cleaning because (as I recall) Ozone happily oxidizes anything it contacts, preferring to be regular O2 + a free radical oxygen atom. The free Oxygen can bond with a molecule of stank and modify it to something less stanky, or it can, say, attach to a molecule in a cell wall and kill the cell.
It's like an efficiently burning fire in slow motion. I think oxidation is part of what makes your skin age; as you age, the damage created by environmental oxidation is repaired less and less by your body, until you just wither away. That's the idea behind taking certain vitamins that are supposed to block the damaging effects of free radicals in your body.
Of course, when you have something that stinks, you'd prefer it be destroyed by oxidation.
Unfortunately, plastics are among the hardest things to clean because they can absorb odors and its very hard to suck the stink back out. Stink isn't just something on the surface you can wipe off in most cases.
Spraying perfume just adds a new smell on top, which might not outlast the stink itself. I think Fabreze is a corn based chemical that works along the same principle as ozone. However, it leaves a residue on hard surfaces; it's designed for fabrics.
Sometimes when you have, say, a guy who dies alone in a house and his body fluids drain through the floor, or, in a moment of anguish, someone decides to end it all using a shotgun, you have a situation where you just need to throw things away.

Since when is that the criterion for a post adding to the discussion? You must think Ask Slashdot is a free consulting service we are running here. The discussions are for the benefit of everyone who participates, not just the OP, and posts that don't contain solutions are still allowed.
Several months ago a PHB posted an Ask Slashdot article asking for someone to write a shell script for his company. He was promptly excoriated by hundreds of unemployed geeks for being a cheap bastard. (Although his Ask Slashdot article was a success because someone did post a three-line shell script that met his stated requirements.) I don't remember any demands for downmoderations on posts with no shell scripts in them, or suggestions that people "just say nothing at all then" if they didn't have a shell script to post.
If someone from a corporate pig farm asks how to get the pig stink off his computers, posts about corporate pig farms in general should be expected and are entirely on topic for the discussion. The OP opened the door, and there's a lot to say about them. They crush family owned farms which can't compete with the vast economies of scale- which can only be achieved legally thanks to extensive lobbying and political corruption. The farms enjoy exemptions to environmental laws that still apply to everybody else. They regularly cause environmental disasters every time there is a flood. The stench they generate destroys real estate prices for miles downwind. People have lost everything when these farms get built near their homes. And unlike nuclear plants, jails, waste incinerators, or sewage treatment plants, NIMBY is entirely justified here since corporate pig farms do not serve the public interest at all. We aren't allowed to talk about this?
Frankly, 600 posts about rubbing alcohol does not make a very interesting discussion.
