Drain Odor Elimination in Commercial Kitchens and Floor Sinks

Floor drains harbor biofilm — a layered bacterial community that releases volatile compounds whenever water disturbs it. The smell rises out of the drain on a schedule that matches dish-pit activity.

Why bleach makes it worse Bleach kills the surface organisms, leaving the deeper biofilm intact and primed to repopulate aggressively. Within days the smell is worse than before.

What works Enzyme and bacterial blends that digest the biofilm layer by layer, dosed nightly when traffic is low. Within two weeks the drain stops smelling. Within a month it stays that way without intervention.
