I’ll be straight with it. I’m a smoker, I smoke inside, I have a PC that is also inside. I want to clean my PC thoroughly to buy it a few more years. I know about the q tip method, and the compressed air, and general methods of cleaning out gunk and junk from PC parts. But this boy is way too gunked up for a regular cleaning. So, I reckon, the easiest way to clean it is to dunk the dirtiest parts in a bath of isopropyl alcohol. I was considering acetone at first, but it’s way too strong of a solvent, and alcohol should be better at dissolving organic residues. Is this a good idea?
I hereby submit this query to the council, and await judgement.
Lol smokers

You can buy yourself and your electronics a lot of years by cutting the smoking :)
Technically you could submerge parts in isopropyl alcohol. The concern with liquid is primarily corrosion and causing shortages. If there is no stored electricity in the capacitors, the isopropyl alcohol shouldn’t cause any corrosion. It would not be the best way to clean it, in reality, but you could probably do it. I would just spray some on and gently clean it with an old toothbrush.
Smoke, especially cigarette smoke, gets onto everything and is awful to try and clean. I won’t buy used electronics used in a smokers home, or much of anything for that matter.
No dunking, and make sure what you’re buying is mostly alcohol (> 95%) and not water/alcohol mixtures often used for disinfection. Using in combination with e.g., a toothbrush is probably your best bet. IPA (and acetone) can strip some adhesives and cause certain kinds of electrical insulation to swell or dissolve, so a targeted approach is better. IPA is flammable (though less so than acetone), so be careful/well ventilated when allowing parts to dry, and ensure parts are fully dried before reconnecting to power.
IPA itself is only about twice as toxic as ethanol and certainly less problematic by inhalation than tar in the long run. I wouldn’t bother with a mask mostly because it won’t do shit unless it’s a cartridge respirator. However, IPA can sometimes facilitate skin absorption. IDK specifically about tar buildup but recommend wearing gloves (disposable nitrile is fine).
When I worked at an eltronics recycling center (we repaired and resold PCs and printers) we used isopropyl alcohol in spray bottles to clean pc parts. It worked really well. Don’t dunk anything! Just carefully disassemble, spray the part (let the run off fall onto a collection pad), and let it completely dry before reassembly. It may take a few rounds depending on how dirty the part is, resist any temptation to scrub off build up on electrical components. If contaminates absolutely will not come off use a circuit board cleaning “paint brush” with circuit board pcb cleaner to gently clear it or better yet, leave it be. The enemy of good is perfect.
WARNINGS: Wear gloves, eye protection, and a mask. Follow all ESD safety protocols to protect computer parts. If you disassemble the cpu add more thermal paste. DON’T SPRAY THE PSU, if necessary use alcohol on a wash cloth for the PSU exterior. You can speed up dry time by air blowing excess liquid off but be aware this may splatter dirty droplets around the space. Only clean your PC like this in a well ventilated space. Only attempt this if you are comfortable disassembling and reassembling your pc. However long YOU think your computer needs to be fully dry, double that time to be safe.
Also as a bonus. You can put non electric components in the dishwasher. No soap, no heat, as long as they fit and won’t get dinged up by moving dishwasher parts. SERIOUSLY DO NOT HEAT DRY OR WASH ON HIGH HEAT.
I also throw my mechanical keyboards in there but there’s always a chance they won’t work after - so far tho it’s been a success (obviously I make sure they are fully dry before I use them . If you attempt this - at your own risk.
But in all reality, spraying the PSU with high concentration IPA is fine so long as you remove it from the power source and mobo, and discharge the caps.
Not to jump on the smoking hate train - I get it, smoking is very pleasurable and insanely addictive - but have you thought about just smoking outside?
I would never smoke in a room I spend any time in. It’s a funny mindset, as I used to smoke inside in my 20s, but when the ban in bars came along it just sort of became second nature.
These days I rarely smoke, but vape more than I should. The vaping is starting to give me a dry tongue that feels like a fading pizza burn. I plan to stop… Soon…
As a guy who’s cleaned far too many smoker fucked PCs.
99% Isopropyl and a tooth brush is what you need. It won’t be fast, but you need that kinda precision and attention to make sure you got everything.
You might also consider just replacing any fans. I don’t know if you have a laptop or a desktop, but a laptop fan is a bitch to clean
Wow at this point id more seriously consider to quit smoking or at least stop doing it inside.
I would highly advise against this! That would be a health and fire hazard waiting to happen. Isopropyl is good for cleaning your electronics but I wouldn’t bathe them in it.
If you still want to try submerging your PC in some kind of liquid, you can try mineral oil. This was a trend in PC building back in the early-mid 2010s but seems to have lost momentum around 2017/2018. I’ve never done this myself so research thoroughly. Other than that, stick to water-cooling.
Also, at the risk of sounding like an asshole, I would advise quitting smoking.
How would cleaning your computer by dunking it in IPA cause a fire?
Their post didn’t sound like they were going to RUN it submerged in alcohol… Just dunking in the alcohol to clean it off. I don’t think mineral oil is going to help clean the parts much.

From what I recall, it stopped being a fad because outside of the cool factor, it was found to be horribly inefficient (cost/performance) at actually cooling the computer compared to air or water cooling.
Have you thought about FIRE?
How is fire relevant?Nvm, I thought you meant it could cause a fire.
Mostly just leave it be. The smoke is on the outside and as long as it’s visually clean enough it’ll be fine.
Make sure that ventilator fans still run smoothly, and as needed, replace those, as cooling is extremely important
Now all you need is a lighter, which as a smoker I’m sure you have handy! 💥

Is it not working in its present state?
If it’s working all right, I’d just leave it be, and if you don’t want tar buildup in your next case, get a case that has an air filter on it that you can replace, or run an air purifier with a filter in the room.
Isopropyl alcohol damages certain plastics.
And metals
Absolutely no way.
It is dangerous to have a flammable, volatile chemical pooled up like that. It’s a fire hazard, not to mention the fumes from it.
Just don’t
Isopropyl alcohol and a toothbrush. Turn off power to the PC. Hold power button for a minute. Unplug and disassemble. Get one of those chemistry squirt bottles (google lab wash bottle) to put the alcohol in, squirt it on the place to clean, brush with the toothbrush. Repeat until at desired cleanliness. Then take canned air and spray out under all the parts. Allow to dry. It’s dry when you can spray under the big components and not get any alcohol out.
I used to assemble, test, repair, and clean PCBs of all shapes and sizes. That’s what we did when we had to spot clean a board after a repair.
The jankiest way I’ve cleaned a PCB was to run it through the dishwasher without detergent, then wash it down with RODI water to demineralize, then alcohol to displace the water. It works, but you gotta be damn sure that you’ve washed away any mineral deposits and given it plenty of time to dry.
