The Watertown City School District has a new way to tackle germs.
Meet Protexus, an electrostatic sprayer designed to kill germs, cold flu virus, e-coli - anything harmful to students and staff.
It's easy to use. Handlers put a chlorinated tablet into the attached water bottle, pull the trigger, and spray.
Schools officials say it's a proactive approach to cleaning, not a replacement for traditional cleaning methods or crews.
