Vetericyn brand ointment (get the type for reptiles!) Yes, it's different from Betadine (aka povidone-iodine) but both are topical antiseptics & both are considered safe for reptile use (dilute the Betadine to appear like weak tea). Vetericyn is a water-based ointment made just FOR reptile use, & unlike petroleum-jelly based ointments (such as Neosporin), it won't mess up their skin & future sheds.
Never heard of F10 being banned in any states, but IF (?) it is in California, it's likely due to the environmental harm it causes when disposed of carelessly- just guessing. Former Californian here.
