    Where do people buy alcohol/alcohol wipes for cleaning thermal paste from CPUs?

    It has to be 99% pure, right?

    Probably a bad idea but I usually use aftershave tbh. I used to use baby wipes but they don't have alcohol in then anymore afaik. Just dry them off afterwards. Never had a problem. Why 99% so it all evaporates? No residue I assume. Also use white spirit. Which is probably better.

    That said I've never had a really expensive cpu or board I was super worried about.

    Isopropyl alcohol is what you need, it cleans and evaporates quickly without leaving any residue on a surface.

    You can probably pick it up in a local pharmacy over the counter.

    Man after my own heart. Kitchen towel sprayed with window cleaner. Perfectly fine. (Don't spray it at the CPU, if that's not obvious)

    Small tip, Isopropyl alcohol is great for removing permanent marker so it's worth having about for those type of heavy duty jobs. Other tip, don't leave permanent markers on your desk when you have young kids.


  • Closed Accounts Posts: 22,648 ✭✭✭✭beauf


    I guess main issue if its flammable and it leaves residue. Could be a bad combination.

    I got a bottle of TIMClean off Amazon a couple months back, but isopropyl from the chemist would do the same thing

    I use 70% without issue.


  • Registered Users, Registered Users 2 Posts: 10,013 ✭✭✭✭Wonda-Boy


    Yeah I have been using Iso Alcohol since I built my 1st rig back when man was inventing fire and ZERO issues. I mean its not like you are pouring the stuff over components!!!

    I dip cotton buds into the cap with some solution in it use one side when dirty flip it over and use the other and repeat if particularly grubby. Then use another DRY BUD to wipe off excess which there is very little to none and then good to go.

    Any chemist should have 300ml bottle for about 5-8 De Niros.

    I had a hard time a while back trying to get my hands on some..went to 3 different chemists..they said that "they dont stock it" because it was being "abused"...i managed to get some in a german online store at the time..the "abused" thing made me shiver..wtf were people drinking it?

    Its an Irish thing - health and safety overkill. Think you are supposed to pay multiple of the price and to get tiny quantities of purple methylated spirits.

    Same when i wanted to do some Retrobrite (making old console cases white again) - wasn't able buy the Hair Salon hydrogen peroxide solution.

    Both seem to be available in hardware or supermarkets in uk/usa.

    Yeah it's a common thing with chronic alcoholics, especially any of those who are supposed to be on a detox etc, they drink small bits of it because of the high alcohol percentage and the fact it's odourless. Absolutely destroys the pancreas and liver.

    there is a guy on ebay.ie that sells it I have most of a litre here of 99%

    it's shipped from ireland and I had it within a couple of days.

    You have to give full address with eircode and it has to be the same as billing details so I presume there's some sort of record kept for who is buying it

  • Registered Users, Registered Users 2 Posts: 36,169 ✭✭✭✭ED E


    For cleaning PCBs, 90% plus.

    For cleaning an IHS? Fócking dettol would do. Really doesnt matter.


  • Registered Users Posts: 2,304 ✭✭✭madcabbage


    I've used surgical spirits myself when i couldn't source isopropyl locally.

    I think thats the UK name for it - or sometimes also Rubbing Alcohol in USA. Same stuff - only sometimes its watered down - make sure to get high 90% and you can use it for recovering water damaged electronics (you can wash electronics no problem with alcohol to get the water out).

    It should be available in Ireland as its the main ingredient to WHO's home made hand sanitiser
    https://www.who.int/gpsc/5may/Guide_to_Local_Production.pdf

    I use it my IPA in a Dealz spray bottles - its really handy when you need get a sticker etc off.
    https://www.dealz.ie/324423-travel-bottle-bottle-7-pack/

    - I don't use the cap of the bottle, as many do, so as not to contaminate the whole bottle with oil or whatever I'm cleaning.


    oh - and I dont think its very dangerous - but I would be trying avoid getting the neat stuff and leaving it on my hands or breathing in any fumes off it. Its also of course flammable - but evaporates in seconds and leaves nothing behind so the item being cleaned is not left flammable then of course anymore.


    For cleaning heat sinks - I've got some stuff from the Artic Silver guys I use - it smells like lemon :)

    Hi everyone,

    Sorry to bump an old thread, but I'm likely to re-do my CPU thermal contact soon and have a few technical cleanup jobs to do (keyboards, monitor etc.), so I'm interested in getting some isopropyl alcohol for that. Has anyone tried getting it in a chemist or hardware store or anything recently?

    Where are you based? I've a good bit of it here in the drawer. Wexford based.


  • Registered Users, Registered Users 2 Posts: 8,877 ✭✭✭SeanW


    Not near me, but thanks anyway. I'll look in my local chemists next week and if not, get some from Amazon or ebay or similar.

    The Irish guy on ebay doesn't have any at the moment. Just checked there all he has is degreasers and distilled water. Not sure how it works importing from England. Dont know would they post it here it may be controlled?


  • Registered Users, Registered Users 2 Posts: 4,436 ✭✭✭Homelander


    If you're really stuck white spirits and a proper good pat down to remove the film isn't the worst for normal use by any means. used it countless times and it's fine.


  • Registered Users, Registered Users 2 Posts: 1,879 ✭✭✭Simi


    I've used nail varnish remover without issue before if you're really stuck.

    I buy mine in Lidl. Rachmaninov it is called I think...

    It's a multitasker, can clean the gut as well.


  • Registered Users, Registered Users 2 Posts: 215 ✭✭manshay


    Isopropyl alcohol 1L (Foran brand) is available from either of the 2 main pharmaceutical wholesalers in the state. They offer next day delivery into any pharmacy. I have it for sale in my pharmacy, and I have a bottle at home for personal PCB use. It will likely cost you c€18 for 1L.

    I bought a bottle on adverts.ie


  • Registered Users Posts: 49 Tin Man


    Anyone ever tried using the Boots surgical spirit?

    https://www.boots.ie/boots-surgical-spirit-b-p-500ml-10075125

    Ingredients
    Active ingredients: Methyl Salicylate, Diethyl Phthalate, Castor Oil.
    Other ingredients: Ethanol 90%. Methanol 5% w/w.

    I'm looking to clean the thermal paste on a CPU and cooler.

    (Well, I'm actually trying to fit a 320mm GPU into an ITX case for a friend. The case advertises that it can fit 320mm but the opening isn't 320mm wide. It has to go in at an angle which means removing f-ing everything that could get in the way and then rebuilding the PC around the GPU)

    Contains castor oil - doesn't sound like an ingredient that would evaporate easily.

    As per previous post isopropyl alcohol 500ml is available from any pharmacy. It will cost approx €18. In stock or ordered for next day.

    I've never ordered isopropyl alcohol from them but they have deliver plenty of electronic products to me with no problems.

    As others have said, just walk into your local pharmacy and ask them. If they don't have it they'll order it and you'll have it next day or so

    Really depends on where you are. I got a bottle no problem in Cork, but I've never been able to buy it in a chemist in Dublin - they usually just straight out lie that they "don't carry it"; Some even attempted to claim they "can't sell it to the public". Apparently people DO drink it and so chemists want no part in someone making the Hindenburg out of their liver (that's also why it's taxed as if it was Vodka, I guess). A 1L bottle on "denatured alcohol" (aka cleaning alcohol) in continental EU costs around 2 Euro, just sayin'.

    Other than that, I clearly must look like an alcoholic, what can I say :D

    Alternative sources - most "contact cleaner" products are nothing but IPA, IF you can find any of these in physical shops in Ireland; Maplin used to have them, but they've been no more for a long time.

    Arts&Crafts stores, as well as Model Kit ones might have some as it's used as an acrylic paint thinner; It's again expensive, like 8-10 Euro for a 250cc bottle.

    That said, I've also been using the cheapest nail polish remover that you can find in Tesco and similar stores - the one that is basically pure acetone; Make sure it has no "hand protection" cream or sh1t of that guise in it. Been using it since the 486 days and always worked perfectly.

    If it's for CPU cleaning, in all fairness modern IHS could probably be cleaned with a severed cow's tongue and whale fat, they're just big huge solid bricks of metal; We're far away from the AthlonXP days of semi-exposed die and a thermal paste cleaning and application process that was akin to handling high explosives. If it's a GPU that's the "patient", then more care is required.

    I am a pharmacist, not familiar with anyone trying to buy it for consumption.

    Methylated Spirits caused many deaths, it has bizarre rules:
    Retailers must buy a licence to sell it, cost €12.
    You cannot sell it from Saturday 9pm to Monday 8am. You can only keep a maximum of 18.5L.

    I don't think there is extra tax on it, there is just one supplier via pharmacy, the retail price is based on their price.

    Thanks for that -
    I wasn't able buy it at my local pharmacy either - I wanted it for cleaning / restoring old electronic devices.

    - same also with peroxide - I wanted to do something called Retro Brite - Dilute Peroxide and UV light is a technique to whiten old brown and discolored console plastic shells. Seems readily available over the counter in UK, Australia and USA

    Chemist told they could not sell it here - tried also a shop locally that sold hair salon products - wouldn't sell it to me either even after explaining what its for- is this true that it cannot be sold in Ireland? t.y.

    No we also sell hydrogen peroxide! It is used to make crystal meth though, think breaking bad! We have a professional responsibility to ensure items are not abused, but if someone gives me a coherent reason I have no problem selling any of these products. However if I was asked for several bottles without a reasonable explanation it may become unavailable!

    what you want is this

    they are small bottles so get a few

    I recently did it for my Amiga A500 and A1200 which you can see the results here

    I mixed it with Vanish or Formil if you go to Lidl
