Do I Need 99% Alcohol for Cleaning My PC?
Asked by
TechNinja42
I've noticed a lot of conversations about using 70% alcohol for cleaning electronics, which has made me wonder about the actual effectiveness of higher concentrations, like 99%. Since 70% is 30% water, I can't help but think that might not be the best option for delicate components. Can someone clarify if using 99% alcohol is better for cleaning? If I do go for the 99%, can I safely power on my PC right after cleaning, or should I wait for it to dry completely?
Answers
The 30% water in 70% alcohol isn't actually the problem; it's the impurities in regular water that can cause issues. If you soak your components, any remaining moisture can be harmful, but if you wipe clean with 99%, it's usually dry within seconds. Just make sure it doesn’t pool anywhere!

If you can get your hands on 99.99% isopropyl alcohol, that's ideal for cleaning. It dries out super fast, leaving no residue! But usually, anything above 70% is good. Just avoid letting it drip too much.
SuperSafeSam: For sure! I've also used 93% with no issues, it does the trick.
MrCleanMachine: 99% definitely has its perks, like less drying time, but the lower stuff works too.

Honestly, if you can’t find 99%, a higher percentage like 91% or even 70% works fine too. The only downside is the extra drying time, but it’s really not a big deal if you let it air out a bit before powering up the PC.
QuickFixGuy: Yeah, I’ve used 70% before and just let my PC sit for a few minutes before turning it on—never had problems!
ExpertCleaner: Same here! 70% is fine in a pinch; just don’t be too generous with it.

You really want to use isopropyl alcohol when cleaning, especially at 99% purity if you can find it. It's perfect for cleaning stuff like thermal paste, and it evaporates quickly. Just remember, it’s not advisable to use ethanol, as it's usually more expensive and isn't as effective for these purposes.
CuriousCat22: I get that! But isn't ethanol okay for cleaning too? I just thought it was another option.
DIYGeek88: Ethanol can work, but isopropyl is generally cheaper and does the job faster!

TechSavvySmith: Exactly! It's all about not letting the moisture sit. You can use distilled water too, but allow it to dry thoroughly before turning your system back on.
WaterWatcher: Right, I've used distilled water myself with no issues, just let it dry!
