Mild heating to increase the vapor pressure will greatly accelerate the evaporation, the Arrhenius equation would predict 2-3x faster for 10 °C rise in temperature. Also, using the fattest possible vacuum hose and fittings will increase the pumping rate in m3/s proportionately to the hose cross-sectional area until you reach the intrinsic rate of your pump. Almost all vac roughing pumps' flow rates are limited by the hose, not the pump.

[@ralanham76]

So it’s basically the same as a compressor, but in reverse ?

[@GermanTopGameTV]

@@ralanham76 It is literally the same mechanical component as a compressor, just the high pressure side is released to the atmosphere and there's a check valve on the vacuum side installed. You can turn any compressor into a vacuum pump.

[@Spirit532]

The reason this works is that most powerful smells are volatile organic compounds, or VOCs. Pulling a vacuum will pull all those out as vapors(and into your rotary vane pump's oil, lol), which will make it smell less. All the smoke, dirt, and everything else that can't evaporate, will still remain there. But your shirt will be extremely dry after a while.

[@SeanBZA]

So remember with a vacuum pump regular oil changes are important, old oil causes issues, and if it is black and looks like tar you should have replaced it a long time ago. My vacuum pump has it's oil changed about every third use, or if I see any cloudiness in the oil.

[@lunaqueer]

​@@SeanBZAI'm new here, what kind of oil should be used in a vacuum pump?

[@SeanBZA]

@@lunaqueer For best results you get special vacuum pump oil, that has low VOC generation. However I just use regular mineral oil for refrigeration, which is a plain mineral oil. This works well enough, and the oil is cheap enough.

[@SeanBZA]

The oil I used was Reniso 63 or 32, a plain mineral oil, generally used in large refrigeration compressors as lubricating oil, and you can use any straight mineral oil there, though using the refrigeration oil is better, as it does not have any additives, and is meant to be run with refrigerant in it. first time I used the pump to dry out a wet system that oil went white in a few minutes, so stopped, changed it out, and carried on, needing to do it again before leaving the pump running overnight. Then it was dry, so refilled the system, and then took the pump and changed oil again, as it was then only slightly milky. Refrigerant oil is about the cost of regular mineral car oil, vacuum pump oil is around 5 times the cost. Even used the refrigerant oil to top up the car, as it is basically a SAE30 oil. Makes a nice general purpose oil to have around, does not damage any copper at all.

[@scottiniowa1]

[@SmallSpoonBrigade]

It just removes volatile substances, it's not going to remove things like dirt and I wouldn't necessarily trust it to remove or kill bacteria. So, if you need to remove gas fumes from a shirt, this probably would help, but most other things not so much.

[@Buckets41369]

​@@SmallSpoonBrigade Most species of bacteria will die in near-perfect vacuum with the exception of spore-forming bacteria such as Bacillus.

It's easy enough to put a hook in a length of straightened clothes hanger and pull it from outside, just feeling around blind. But the fact that you have handy viewing windows makes it completely trivial! Just thought you should know (from someone who's come home to find their tools missing)

[@vegigun]

Isn't a solution for this wrapping the cord in a pool noodle or something to stop them from being able to get it over the door to pull on and making it really obnoxious to pull on with a tool? You still have the safety of being able to disengage the opener, but more security vs the attack.

[@henryptung]

Bringing in fresh air and pumping it out again provides a current for the more clingy molecules to be pulled away.

It makes sense because you are allowing all the volitile compounds which make up smell to boil off. Smoke from the fire is probably 2 fold though, both volatile compound and micro carbon/partially decomposed cellulose.

[@scorinth]

I suspect - though I don't have a vacuum pump to test this - that the vacuum pressure in the chamber is indicative of how much remains of the smelly compounds. The whole point is to get them to change into a vapor, and If there's a lot coming off, the vacuum pump will struggle to remove them faster than they come off the clothes. Once the offgassing slows down, then you'll see the pressure in the chamber really drop. Just be aware that, like, _most things_ will continue offgassing way longer than you probably want them to. For example, spacecraft hardware has to be designed carefully because a lot of plastics and lubricating oils will simply evaporate in space. The vacuum these pumps can reach is much less intense, but I'm not sure it couldn't become a problem.

Engineer here: Reducing the pressure reduces the temperature at which things vaporize. You can add some heat to vaporize more, faster. As the materials vaporize off the vacuum pump pulls them out. Also, I highly doubt you hit 30"Hg vac as that's true vacuum (unless you're deep in a cave), which is difficult at best. 28"Hg is about as good as you're going to get with a setup like that, at least at sea level. It would be interesting to see how it works if you were to dampen/wet the clothes first.

[@MobiusHorizons]

When you think about what smell is to begin with, I think it makes sense. In order to smell the clothes must be off gassing compounds that you are detecting with your nose. By leaving them in a vacuum, you increase the rate of off gassing, thereby accelerating the process until the contaminant causing the smell is exhausted. Or to say it differently, it’s like accelerated airing out that you might do with a jacket that smells like campfire.

Considering that our smell is just detection of volatile (often organic) compounds, vacuum deodorisation makes a lot of sense. If you have a vacuum setup.

[@RottyScoots]

So in order to clean things. You need to follow the TACT principle. You need to balance Time, Agitation, Chemical action, and Temperature. Pulling a vacuum alone would only leverage Time and Agitation. You will need to compensate with chemical action and temperature. As well as a form of agitation that can displace the contaminant. Traditionally, Wet cleaning uses water to extract AND displace the contaminants. So you may have been able to deodorize using vacuum alone. But the physical matter would still be in the fabric. And its possible it could reactivate when introduced to moisture. But this is an interesting method nonetheless!

Our physiks-teacher at the first lesson with him told us that there is no valid excuse for having oversleept exept if you prove to him you put your alarm into a vacuum-chamber

[@ProffesorFarnsworth]

Joe, serious question - can you please put some kind of high density Styrofoam (like the kind found in helmets) in the vacuum chamber and report the results?

it would take less time to wash them, but its still interesting.

Given that odors must be both a vapor and something your nose can detect, it means that anything that smells has odor molecules constantly leaving the substance and moving into the air where you can smell them. There can't be an infinite number of odor molecules so whatever vapor you're smelling has to run out *eventually.* It's just a matter of if it's hours, days, months, years, centuries. If you just leave a campfire-smelling jacket out for a few weeks you'll find it looses the odor on its own. I think what's happening here is, the low pressure is making it very very easy for the odor molecules to escape what they're stuck to (the jacket). What would normally take weeks is now taking hours. I bet if you heated it at the same time (infrared heater perhaps, given the lack of air) you'd get it deodorized even faster.
