My youngest daughter got pink eye several times in a span of months when she was in Kindergarten. I would sterilize the house but she would contract it again. So I put together a "little basket" for her teacher full of alcohol wipes, Lysol spray, antibactrial soaps, and a pinesol. I told her if the janitorial staff won't clean her room properly then she has to do it. Pink eye in her class went down 85% after that. :)
