What is the difference between denatured alcohol and rubbing alcohol

Denatured alcohol has a bad taste, smells foul, and is poisonous if ingested. The additives exist to deter individuals from attempting to consume it for recreational purposes. Typically applied as a solvent, denatured alcohol is suitable for numerous application needs.

Rubbing alcohol is considered to be a surgical spirit rather than a methylated spirit since it is used in medical environments as a topical application. It is a type of denatured alcohol prepared from a special solution consisting of roughly 70 percent pure ethanol/isopropyl alcohol in concentrated form.

So roughly denatured alcohol is mainly used for solvents and fuel additives, and is mainly used by hobbyists, painters, and the like while rubbing alcohol is an antiseptic and can clean minor spots and is used in more medical things.
