Any pharmacy. You want 99% Isopropyl alcohol. (70% Isopropyl alcohol has
oils added to it. Don't use it.)

I have never seen 99% alcohol for sale. The 91% has less water in it
than the 77% stuff. If there is oil in the alcohol, then it must say
so on the label (at least in the USA).

Google for "anhydrous Isopropyl alcohol"

Here's 99% alchol for sale, probably in the US;

Anhydrous is kind of nasty, is sucks all the moisture and oil from the
skin. We used to get bottles of the stuff to clean disk drive packs
and heads, tape heads, also. And if you leave the cap off for long it
isn't anhydrous any more.

IMHO 77% alcohol is fine for what we use it for, now. As long as the
other 23% is distilled water.

If it to use to clean heatsinks and chips etc then I use stuff in the yellow
can 'Solva' something or other that I get from my local electronic component
shop. It is normally used for cleaning circuit boards and I emailed the
company asking if it could be used to clean cpu etc and they said OK, and it
works great.

It's not as common as the 70% or the 91%, but it can be found if you look around. I just picked
up a pint of 99% yesterday from the market for $1.59.

I do know that anything over 91% can't be obtained with fractional
distillation, which means there may be additives (other than pure
water).
