Finally, alcohol. Interesting points about
Prohibition (which we didn't
have over here). Thank you whoever posted them (even though off topic).
Denatured alcohol here is still "Methylated Spirit" - i.e. it has had
methanol added. It has also had pyridine (I think) added to make it
look purple and taste foul, and it is therefore even more poisonous, but
it doesn't leave a residue.
Actually, I considered the topic of alcohol to be on topic. One of
the things I have had to deal with is old circuit boards that were
hand-assembled. Typically, the solder side of these boards are
covered with flux resudue.
Now I realize that this residue is inert, and has reasonably good
dielectic properties, but it makes the assembly look like h***. I'm
into the habit of cleaning this stuff off, and to me, nothing works
better than pure 'hooch' (chloro-clean is a tad expensive, and I
consider MEK to be a bit too harsh).
