Ok, so *thats* why modern denatured alcohol smells like that! I
recently bought some from a hardware store to clean circuit boards,
and it smelled very strange to me-- it had an MEK 'edge' to it. The
last time I used denatured alcohol was almost twenty years ago-- I
was un-aware that they had changed the 'formula'.

Anyway, I'm seriously considering shelling out some real $$$ for
ethanol-- this new denatured stuff leaves a residue which the old
formula did not. (Anybody remember 'Zeracol' ?)
