Antiseptic

It seems to me that each of us feel impressed to prepare for specific situations. Some are gathering extra pads/tampons, others planting gardens, collecting books, etc. I feel an urgency to prepare for first-aid care. I’ve got all the basics plus suture kits, Israeli bandages, SAM splints, sterile gloves, and such. What I don’t have is antiseptic. Is betadine enough or should I have alternatives? (I have alcohol, hydrogen peroxide, manuka honey, vodka…)

My reason for having these items is to share them in case someone else needs them. I don’t know if I’m just throwing money away but it feels really important to me.

Many thanks in advance, prepped friends!
