Where to usually find isopropyl alchohol 99.9% or like atleast 70%?

I don't know where to find them.

Don't know about the percentage, but you can usually find it at most pharmacies and some gas stations.

Larger grocery stores near me carry them in the pharmacy, but your local drug store should have some too. It was sold out for a couple months because of COVID, but it should be back in stock pretty much everywhere at this point.

99.9 is going to be rough.  Really pure alcohol can be dangerous. 70% is the breakpoint for effective against viruses so it got swept up by the covid thing.  There are a lot of “hand sanitizers” that are 70% alcohol though. 

[mariushm]

For health purposes (kill bacterias and stuff like that), 70-80% is better, as it enters the fat cells of bacterias much easier and faster than higher percentage. 

 

For electronics, it's recommended to get at least 95% purity. 

 

99.9 is tough but not impossible, 99.7% is probably plenty.  A lot of companies don't bother advertising more than 99.5-99.7 because of the way the alcohol is sold ... if it's sold in plastic bottles, humidity is absorbed through the plastic over time and each time you open the bottle and therefore the purity goes down.

 

Due to covid and all the recent events, it may be harder to find high concentration, because it's used in all kinds of wet wipes and disinfectants. 

 

If you can't find it in pharmacies, try veterinarians and vet stores, isopropyl alcohol is used with animals especially horses, so you'll find 70% or better stuff there.

You may be able to find it at a hardware store, though it might be best to just get it online. There seems to be plentiful of 99% isopropyl alcohol at reasonable prices on Amazon where I live.

Isopropanol 99.9% used for nail polish removal (among others). If you're looking for cleaning electronics, this is what I have. Found it on amazon. It will, however, remove paint. Be careful.

NOT to be confused with ACETONE which is more common used for nail polish removal  ... acetone is another good solvent, but a bit more toxic (not a good idea to breathe in or smell the fumes for long periods of times)  and can damage some plastics and can remove paints (printed text on components) 

 

Isopropanol should not be strong enough to remove (most if not all) paints, you're probably thinking of acetone.

Not sure where you are but a lot of pharmacies and even electronics stores have 99.9% isopropyl alcohol. If there's a Jaycar near you (if you're in Australia) then they'll almost certainly have it.

[Vishera]

In my country you find them at the local supermarket.

Yes. Thanks for the addition.
I have this one and it's served me well

12€?!,That's very expensive.

I buy 98% for 1€ at my local supermarket.

[lewdicrous]

Depending on where you live, you might not find them easily.

If you're looking to clean thermal paste, then I found that alcohol swabs work well. Those are easier to find where I live. (local pharmacy)

[mariushm]

In some stores, price may be higher because it includes increased shipping costs. 

 

The alcohol is considered flammable, so it may have to be shipped by train or truck/car instead of planes, and therefore it may cost more to ship compared to other items in the store, so they're hiding the increased shipping costs in the value of the product.

70% is usually fine. I prefer the wipes.

Quite right.  If you just need some to remove thermal paste, 70% is just fine.  Clean the paste off and then use a micro-fiber cloth to dry the surface and you are good to go.

I would avoid 70% because the other 30% can contain thickeners and it will not evaporate, leaving residue on components. 

 

Another source for alcohol is industrial supply stores and feed and farm stores.

Pretty sure that's just the German name for isopropyl, it definitely does not remove paint... cleaned my cpus,  gpus, fan blades, motherboard etc ,I would know lol. 

 

 

Even says 'isopropyl' on the back lol

It depends on where you live, but you can find 70% at basically every pharmacy and supermarket. 90% or above is more uncommon but by no means impossible to find.

 

You really don't need extremely pure alcohol to clean thermal paste. The alcohol doesn't actually dissolve the thermal paste, it can't because the paste is usually made from extremely finely ground metal. The reason it's used is because it evaporates quickly and does not cause as much rust as plain water. It is also useful for removing oils (fingerprints) from metals so it will leave things nice and shiny.

This is not true if you get properly specified USP 70% alcohol.  It can only contain isopropyl alcohol and water.

Yes for sure.  Nowadays there's so many bad products claiming to be pure that aren't, some arent even iso, that you need to be careful.

 

Strictly on electronics, I'd stay with 99%. For disinfecting surfaces then 70% is more effective.  

 

[airborne spoon]

you can find it at Walmart or similar stores, also rite-aid, Walgreens, exc. 70% is like $2-3 and 90% is closer to $7 or so. I prefer the 90% because it dries faster than the 70% and it works better for other uses around the house.

[bondoao1]

This is what I use on electronics.... I use a lot of it daily.

[FakeATF]

The local shine still.

Where do I find this in Sweden..
