School districts are starting to understand using a low toxic environmentally friendly disinfectant like Hydrolyte is a much healthier solution for children and staff with any kind of breathing issues. PCT Corp. is a hypochlorous acid supplier. Hydrolyte has no volatile organic compounds and does not exacerbate or cause breathing problems yet kills 99.9999% of pathogens. No doubt PCTL's Hydrolyte is one of the best disinfectants for school systems, colleges, and businesses to protect their employees and patrons. Gone are the days of spraying hard surfaces with a cleaner and wiping it with a dirty rag thinking it's clean. The EPA classifies surface cleaner surface sanitizer and surface disinfectant as follows. Makes sense to use Hydrolyte disinfectant over anything else.
