I thought food places and hospitals use iodophor. Iodophor will sanitize to hospital standards at the right concentration. And you’re not supposed to use bleach on stainless, which many things in a restaurant are made of. First rule of stainless - no bleachIn a lot of states in the LAW that food preparers sanitize with diluted bleach. Do you taste bleach when you go out to eat? Perfectly safe. I think most brands even include dilution instructions for sanitizing on the bottles.
