Microbes have the ability to adhere to surfaces, whether they are made of steel, stainless steel, cast iron, glass, Formica, plastic, etc., they multiply rapidly thanks to the deposition of organic material and produce a sticky matrix that serves them as protection. In a short time they manage to form a BIOFILM, that is a protective "film" in which bacteria can protect themselves from external threats (such as our cleaning) and to profile undisturbed forming real "communities". HOW DO YOU KNOW IF YOU’RE FORMING A BIOFILM? HOW CAN ONE INTERVENE IF ONE NOTICES THAT A BIOFILM IS FORMED? HOW CAN WE AVOID THE FORMATION OF A BIOFILM?
