You know what I don’t see on this list..chlorine bleach and iodine not only for disinfecting things in case no water but to help purify water.Iodine is cytotoxic to living cells too and wouldn’t recommend it for wounds less for foot blisters to toughen them and keep them from opening becaue of possibly causing an infection. But if there is no water to wash wounds and if you were camping I would recomend using a form of it like betadine mixed with any water if not alergic to iodine because it kills a lot of bugs, and have some topical antibiotics around.
