In my kits I carry both Betadine and Sterilon (Chlorhexidine gluconate). I use Betadine on regulair cuts and scrapes, but Sterilon if someone is allergic to betadine.
HTH
Btw: Betadine only has a 3-year shelf-life. Sterilon 5-years.
I now use it as well. I just bought some Chlorhexidine 4%(Hibiclens brand) after the vet. gave me some and it worked wonders on a wound my dog had. Before that I had never heard of it.
