💡Most people assume contamination goes down the drain. The truth is, it can come back up.
In most facilities, drains are cleaned last, treated as just another part of the floor. But every drain shares the same anatomy: a drain body, a p-trap, and more crevices than you can count. And those surfaces quietly become a problem.
Over time, they develop biofilm, a microbial layer invisible to the naked eye. Bacteria living inside biofilm can be up to 1,000 times harder to kill than bacteria on an open surface. And research shows drains can keep reintroducing contamination into a space, even after the area looks clean.
Hotel kitchens, school cafeterias, and gym locker rooms all share the same challenge.
⚠️Drain sanitation isn't an afterthought. It's the start of a comprehensive cleaning program.
