What is the difference between grain alcohol and rubbing alcohol?
If memory serves me correctly, grain alcohol is derived from the fermentation of various grains, with the most common being from corn, and it’s safe to consume. On the other hand, rubbing alcohol contains isopropyl alcohol (which is a chemically made alcohol), and usually contains additional water and sometimes glycerine, and isn’t intended to be substituted for either grain or wood alcohol. To drink it would make one very ill and may even be lethal, or cause blindness.
