How are the trays at the airport security lines antimicrobial? How do you make a tray microbial without cleaning it?

I seriously doubt that they are. I wonder where you even got that idea? Here’s something to consider: Even if the trays are completely sterile at the start of the day, even if they are soaked in Lysol and bathed in UV light, the first person in line may have walked through dog-shit, chewing-tobacco, and piss on his way from his car to the terminal. Then he puts his shoes in that tray. Then the tray goes round-and-round throughout the day to haul shoe after shoe after shoe. I don’t care what it’s made of, unless you clean it yourself or see it being cleaned, it isn’t clean or sterile in any way.
