Jerry,
What does NFG mean? Is there a code book somewhere that we should have
access to?

Peter,
In ANY concentration, isopropanol is NFG for human
consumption.

All the alcohols you buy in the drug store have other
ingredients that will
leave a residue. While 99% alcohol is very good, there is
still residue. The
manufacturers add these ingredients so people do not try and
use that
alcohol (i.e., rubbing, isopropyl, etc.) as a basis for a
cocktail.

That has not been my experience with 99% bought from
Long's Drugs locally. It cleans without any residue. Ethyl
rubbing alcohol is denatured with Acetone and sometimes
other materials and does leave a residue. The purpose of the
denaturing is to avoid the liquor tax.
I would be more concerned with so called Vodka. If it is
true Vodka it will have more than alcohol in it.
Another good degreaser is Edwal Anti-Stat Film Cleaner.
This appears to still be 1,1,1,trichloroethane.
