I've got an older PC that I'm upgrading and going to turn into a NAS for my house, and the poor thing spent YEARS as the living room PC in a house full of stoners. Every surface is slightly amber and sticky. Any good cleaners I can use to remove it all without damaging the electronics?

For electronics I would only ever use isopropanol or distilled water. Just make sure you let it ventilate really well for up to a week or so when you finish. And don't try and clean inside the PSU, just replace it if it's really bad.

In this instance, I think I'd just skip trying distilled water. I don't think would help much to remove the resin.

So, get a tub big enough to fit your while computer in, and fill it about half way with rubbing alcohol and a pound of salt. Set your computer in, close the lid tight, and shake it like hell until it's clean.

This is a joke. Please don't do this to your PC.

Works great on glass pipes though.

Better for glass pipes is a mixture of rubbing alcohol (the higher percentage the better) and salt. You want the salt to form a paste so not too much rubbing alcohol. Then you shake the shit out of your pipe for about 3-5 minutes then rinse out the alcohol and salt with some warm water. Et voila you have a shiny clean pipe. Sometimes you might need to do a second scrubbing to get anything left over but usually the first go is good enough. After that I hit the whole thing with bleach just so nothing funky grows in the water and then one more rinse and my dab rig looks brand new.

True, but what works even better than THAT, is mixing rubbing alcohol and salt and shaking your pipe in it.

Alas, my bong is too large for that.

I'd say what works best is shaking the pipe in a mixture of epsom salts and rubbing alcohol.

90%+ ethanol or isopropyl alcohol.

Alcohols dissolve it like thermite through butter

Same as anything else: isopropyl alcohol and q-tips.

Have not seen it suggested and don't know how well it goes with electronics, but using oil to dissolve resins has worked much better for me than using alkohol.

Consider that if it's not on the fan and it's working then doing something can break it. You don't need to clean everything, it's stable.

Honestly, my main concern is various empty connectors and slots on the motherboard that I'd like to use in the upgrading. The DIMM slots, in particular, that are currently empty look like they're coated with resin. I'm not at all sure how that might affect conductivity.

[–] Cort@lemmy.world 3 points 4 days ago* (last edited 4 days ago)

99% isopropyl (rubbing alcohol).

Soak components and air dry completely before reassembling.

(99% dries much faster and 90% and is less likely to corrode anything. Should be available on Amazon by the gallon)

When cleaning glass salt can act as an abrasive, but its true purpose is removing water from the alcohol to get a higher % alcohol. Salt water & isopropanol don't mix so you get a layer of 99%+ alcohol on top of the layer of salt water. But don't use salt for electronics, just buy the 99%.

You can use everclear

[–] charonn0@startrek.website 3 points 4 days ago

I'd use 90% isopropyl alcohol solution. Dampen a clean cloth and wipe away the resin.

[–] watson387@sopuli.xyz 2 points 4 days ago

Use the spray-can electronics cleaner. It cleans really well and evaporates quickly.

[–] Fizz@lemmy.nz 1 points 4 days ago (1 children)

Doesn't the resin form a protective coat or some shit?

[–] Einskjaldi@lemmy.world 2 points 3 days ago

Technically it does make it waterproof.
