When disinfecting surfaces to prevent the spread of a deadly virus, additional precautions need to be taken.
"If you spray a bunch of tables then use a rag to clean all of them, what you basically did was move germs from one place to another," says Chris Gurreri, co-founder of Minneapolis-based Victory Innovations. The startup makes electrostatic sprayers that clean more thoroughly and efficiently. The sprayer gives your disinfectant solution a positive electric charge that causes the droplets to be attracted to neutrally charged surfaces like desks and walls, and to repel each other, leading to an even distribution over surfaces that prevents dripping. After a few minutes, the disinfectant kills the germs and the liquid evaporates. There's no need to wipe the surfaces down manually--just spray and go. A single person using one of the sprayers could sanitize an average-size 100-person office in about 10 minutes, according to Gurreri.
