Is it possible to clean ICs with Pure Alcohol ?

Here, in France, you can buy "Alcool à brûler" in any supermarket. It consists of 90 to 95% ethanol with 5 to 10% methanol. Both are highly volatile and leave no residue making it very good for cleaning.

Boardburner2:
equivalent here is rubbing alcohol.
Composition is different though its pretty good but im sure that there is something else in it , it feels slightly oily after evaporation

The french type cannot be imported to the uk without a licence, i tried once.

Incorrect. "Rubbing Alcohol" is isopropyl, water, and generally some kind of oil.

What he describes is called denatured alcohol in the USA. Ethanol with methanol and often a few other solvents. Works great as a degreaser, but attacks some plastics.

I generally use 99% isopropyl for cleaning electronics, but also use denatured alcohol for some tasks.
