I've heard of neutralizers that you can wash out sprayers with to destroy any remaing poison. But I'm not sure of the name of any. For the winter just make sure there is no moistur left in the hoses so that when it gets cold out ice does not form in the lines. Beyond that theres not much else you can do. I seem to not have much luck with pump sprayers in making them last though. I no plastic is lighter but they don't seem to last like they use to. I just by the chepos now and don't care when they brake.
