Is denatured alcohol a disinfectant?

Denatured Ethanol (DE) or Isopropanol (IPA)?

Denatured Ethanol is considered more effective as a virucidal disinfectant, as isopropanol is not effective against non-enveloped viruses.

Is denatured alcohol and rubbing alcohol the same?

To summarize, rubbing alcohol works as a minor cleaning solvent and is meant to be applied as an antiseptic. Denatured alcohol is used as a solvent, a fuel additive, and for sanding or finishing purposes and should never be applied as an antiseptic or consumed.
