I've read that chlorine mixed w/ water needs to be remixed every day because the chlorine part of it will dissipate or disintegrate or whatever. Is this also true of oxine? I want something I can just use the spray off latches and handles and such (for my own peace of mind) and I've been using lysol (only on the outside of the coop-never inside) but I want something that is safer. But I want to be able to mix up a bottle and just use it every so often without having to remix it daily or whatever.
