I called into the best-known PC repair shop in my town. Here's how it went.
Me: I want some cleaning fluid for electrical components in my PC box.
Him: You don't need any cleaning fluid for that. What do you want to clean?
Me: Oh, fans and heatsinks and CPU's. I'd like isopropyl alcohol.
Him: No, no. You can do without that.
Me: But how do I remove dry thermal paste?
Him: You can use aftershave or perfume.
Me: Oh, thanks. {and exits door}

What about merthiolate? Is that still around?

I don't bother looking at more than 2 pages of hits. TCP means
something to you in your region. To the rest of the world, it is about
networking.

You don't tell something to go use Google. That is being lazy, rude,
and deliberately obtuse. If you claim a Google search will find
something then provide the search criteria; else, you don't show that
even you could find it.

I have a strong feeling that isopropyl alcohol is either banned in the
UK or severely frowned-upon.
Maybe the authorities fear we might use it for getting an instant high;
just sniff the stuff and that's a quadruple whiskey in your system.
We're an unruly lot, all heading for the gutter and the winos' queue
outside supermarkets. (-;

Dumb fucks. Gee, now what are the ingredients of aftershave and
perfume? Yeah, pay high prices for those goods instead of the primary
ingredient.

You sure you didn't make up that story just to make them look dumb? You
should've asked them which brand of aftershave they use (on their
computers, not their face). Then asked them the ingredients of that
aftershave (at which point they'll look like deer caught in headlights).

Maybe they were drumming up business. They'd tell you to use
aftershave, you go home and do it, and later you'll bring in your
computer for them to repair.

No it's not restricted, you can easily get it mail order, just not
stocked in many places over the counter, e.g.

Also contains mercury. Also banned(*) by the FDA in the USA.

https://medlineplus.gov/ency/article/002678.htm

(*) After a study started in 1978, the FDA pulled the GRAS (Generally
Recommeded As Safe) status. Mercurochrome, and other mercury-containing
medicines, got classified as drugs in 1998. Anyone wanting to sell them
nationwide had to go through the rigorous and very costly drug approval
process. No one paid the high price for research and drug approval.
Without FDA approval, the sale of mercury "drugs" across state lines was
illegal, so the products disappeared.

https://www.ncbi.nlm.nih.gov/books/NBK493181/
"Isopropanol ingestion is the second most common alcohol ingestion
following ethanol [grain alcohol] but is the most common toxic alcohol
ingestion reported to the United States poison control centers each
year."

All alcohols are toxic, some more than others. If you're using a cotton
swab to apply isopropanol to sore gums, you are unlikely to injest
enough isopranol to make you drunk or be concerned about toxicity. If
you pour a bottle of it into your mouth to hold your lips together to
drown all your teeth, yeah, a mouthful of the stuff is not recommended,
especially if 91% instead of 70%.

Make sure you don't use denatured alcohol which is grain alcohol mixed
with toxic denaturants to be repellent to humans. Grain alcohol
(ethanol) isn't as toxic as isopropanol, but it is made more toxic with
the addition of denaturants. Usually methanol is the denaturant,
metabolizes into formaldehyde, is extremely toxic to humans, shouldn't
even be inhaled, and causes dermatitis when exposed to the skin. For
cleaning, denatured alcohol leaves behind a residue. 90% is ethanol, 5%
is methanol, and the other 5% are denaturants (that are probably not
identified) that leave a residue.

Thanks. I thought it might also be banned, but I wasn't sure.

That's high proof stuff at 99.8%. That even beats everclear. You only
need 70% for an antisceptic and a cleaner. That is, instead of buying
pure isopropanol, get isopropyl alcohol which is a blend of isopropanol
with water to lower the concentration of isopropanol down to 70%. Those
big jugs of IPA @ 99.8% are far more than you'll need. Make sure to use
in a very VERY well ventilated area if you use the pure stuff.

I use 99% Propanol for CPU and other electronic cleaning uses, and I
use70% isopropyl alcohol for antiseptic and general uses.

Only if you rinse it off (with more isop). Otherwise
it participates back what it initially dissolved
when dries out.

I would just capture the fans, blow the sucker
out and be done with it.

Or find someone with a parts cleaner. Disconnect
the CMOS battery first.

I'm fairly sure my brain treats my fingers as some sort of autonomous
'typing peripherals' and it sometimes forgets who is sending the output
to them ...

For use on skin, the stuff we can readily buy in high-street chemists
(aka surgical spirit) is 90% and has 5% methanol to stop you drinking
it, plus "gunk" that will leave residues such as wintergreen oil, castor
oil and diethyl phthalate.

Given that is is sold specifically to clean/disinfect/harden skin, it
seems somewhat at odds that the safety info says if you get it on your
skin you should wash it off with soap and water ...

> You only need 70% for an antisceptic and a cleaner.

The spray aerosol cans that you get over here (for cleaning
fibre-optics, CD-drives, printers and wotnot) does tend to be about 70%
IPA with water.

The beta blocker is Propranolol.
Propanol is propan-1-ol, isopropanol is propan-2-ol

I can well understand your skepticism. I think I'd probably feel the
same reading this from someone else; or maybe what your excellent
novelist Stephen King might describe as "silly old fart having his leg
pulled by breezy young whizzkid".
But no. I don't seem to engender such reaction from people, and I didn't
detect the slightest piss-taking attitude in the guy.

The only place I met any sign of isopropyl alcohol was in a telephone
call to a local TV repair shop. The chap there said they had a bottle of
it but not for sale; and when I asked where he got it, he didn't know -
probably true, he being just the assistant at the counter.

Anyway, I'm waiting for the postman to arrive with some ordered online.

The TCP in a bottle is some sort of very dilute phenols. I've used it
for years on any injuries. It is much better than other antiseptics
and doesn't sting as much.

I think it is made in France so it may become less available is the UK
now with trade restrictions. I've got half a bottle but my local
chemist shop has no more in stock.

Is it really that hard for you? It's literally only an extra word.
