So would a cup or 2 of boiling water tipped down the condenser tube after
the heads are removed help remove the tainting?
It might, although you usually need to give components a good scrubbing with
detergent, or soak in some active cleanser, to really shift those
Frankly, I wouldn't worry about it. What we are talking about here is a
tiny amount of additional purification which is probably only worth
bothering about if you are after ultra pure ethanol for use with scents or
essences. In that case it is then probably better to go the 'dedicated
path' way and try to keep as much of the heads away from your main product
Just shows how far we have all come on this list (which was supposed to be
