I used to pack Betadine, but the iodine is just too vicious on plastics and everything else in my kit. I use alcohol wipes to sterilize scissors or a pin before working on a blister. I usually have to carry alcohol hand sanitizer for the kids since they like to pick up dead animals, handle tortises, etc. Any sort of animal bite would get a good wash of alcohol. I usually carry Neosporin or something similar.

Cuts usually just get a good wash of drinking water and covered up once they dry a bit. For a big wound I'd have to just irrigate with available water as needed. If I didn't have enough treated water, I'd have to make the toss-up.
