“The difference between denatured alcohol and rubbing alcohol lies in their ingredients. Denatured alcohol is ethanol that has had methanol or acetone added to it, and is meant for lighting stoves and removing stains. Rubbing alcohol is a mix of ethanol and water, and is meant for sterilization.”
Rubbing alcohol is either isopropy alcohol and water, or denatured alcohol and water. Denatured alcohol is ethanol with methanol or acetone added to make it toxic.
I’d be very careful doing anything that might result in the consumption of more than minute amounts of rubbing alcohol.
And neither is for drinking, IINM. They’re ***external use*** only.
