Doesn't alcohol (like isopropol) have like zero surface tension? I know it evaporates super fast which is one of the factors that makes it a good cleaning agent.

That's actually exactly why it's a bad cleaning agent, at least for sterilization purposes. It evaporates before it can kill any microbes.

Yeah if you're using high percentage isopropanol it's less effective. I think the current recommendation is 70% for sterilization purposes as it remains in contact longer. Higher percentages is more for its use as a solvent or cleaning electronics.

I thought the 70% was recommended because it helps maintain membrane fluidity or something like that

Yeah or something with hydrophilic properties with the water help destroy microbes. I love reading about chemistry but keep forgetting.
