BEAR, Delaware (WPVI) -- A Delaware school district demonstrated its newest tool against germs Tuesday.

New hand-held battery-powered disinfectant wands will now be used to disinfect surfaces at Kathleen Wilbur Elementary School in Bear, Delaware, spraying a fine germ-killing mist onto desks, lockers and other high-traffic areas.

"Traditionally we would have to spray it down and then we'd have to let it sit five to ten minutes and then wipe it down," said Ted Lambert, Supervisor of Facilities at Colonial School District. "With the new Protexus wand, we can actually go through and spray it down, let it sit and dry and we're good to go."

Officials with Colonial School District started budgeting for these in their schools last spring, and say the timing couldn't be better.
