PCB flux residue

Interesting - never read the standard before, however section 2.2 says that whilst there's a standard for UK produced CDA (Completely Denatured Alcohol), CDA approved and produced by any other EU state is also allowed.

I have used Ever Clear for board cleaning but it may not be available outside the US??

Essentially the same stuff as Methylated Spirits/CDA - i.e. mostly Ethyl Alcohol (Ethanol), except that it's explicitly made from grain (or corn) - I don't think that the specs for CDA stipulate where the ethanol comes from, just that it's ethanol!

CDA in the UK normally contains a small amount of IPA as well, so you're getting a hit of a secondary solvent too.
