Isopropyl, methyl alcohol, ethanol all the same?

Definitely not. Isopropyl alcohol, also called rubbing alcohol, is used as a common topical disinfectant for cut and scrapes. Methyl alcohol (also called methanol) is used in chemistry to make other substances in industry as well as a fuel. Ethanol is the form of alcohol found in beer, wine, and other alcoholic beverages. You never ever want to consume methanol as it is extremely dangerous and can cause blindness.
