Most rums and vodkas contain 40% to 60% (80-120 proof) so it must be stronger than that to be truly effective.

And, isopropyl alcohol is also pretty ineffective at lysing the lipid layer of bacteria and enveloped viruses...so another reason you wouldn't want to make it yourself out of rubbing alcohol.
