Soap makes water wetter. Kind of. It reduces the surface tension, allowing it to spread out and penetrate better. Making it clean better. So could we produce a surface tension-free water? (lemmy.dbzer0.com)

What about another liquid? Is there a "perfect" cleaner, something that spreads and penetrates like nothing else?

Very interested in the answer.

Homie dats a gas. Or supercritical fluid, which actually is indeed used for "washing" (SC CO2 is used to decaffeinate coffee). However, like others said, surface tension /= cleaning ability. Part of what soap does is increase the effective solubility of things that are not normally soluble.
