With schools reopening, an increasing number of custodians are applying disinfectant spray methods to decontaminate frequently touched surfaces, including school supplies, walls, desks, and chairs, to mitigate SARS-CoV-2 virus transmission between students, and teachers and students in the classroom. In this research, we present a novel characterization method to evaluate disinfectant droplet size and coverage for two types of commonly used disinfectant sprayers and suggest the optimum application practice for them.
