Doesn't the physical action of cleaning do a pretty good job of cleaning off yeast and mold? I would think that the cleaning is at least as important as the sanitizing. Also, even though starsan doesn't kill yeast and mold, doesn't the physical action of rinsing with the liquid knock the yeast and mold off? I have no idea if this is true but it sure seems like it would help.Its these places that don't get physically scrubbed that might be harboring critters and protecting them from a quick coating of star san.
It does not matter how well one cleans when the microbe is yeast or mold. Star San cannot kill these microorganisms due to its mode of action. Dodecylbenzenesulfonic acid (the active ingredient in Star San) kills via attraction to positively charged cells (hence, the anionic part of acid-anionic). Once inside of a bacteria cell, the surfactant goes about wreaking havoc on cellular function. Yeast and mold cells are negatively charged; therefore, Star San is not effective against these organisms.
