That was @lwien - his method is unique but it works for him and I appreciate his viewpoint although I do not subscribe to it personally. All that is in the packs is salt and distilled water. FWIW, I have stored pounds upon pounds of medicine touching the packs and it has never done any harm. At first I wouldn't reuse the packs for fear of contamination coming from long storage but now I don't even worry about that and use them until dry. One thing I will not do is rehydrate and reuse the packs however.
