Betadyne I'm probably spelling it wrong is an iodine solution. It's the only thing I use on any of my reptiles when they have an injury. It also works on mouth rot. Its exactly what the vet would do. Per my vet when I first started in this whole crazy industry. Chlorhexidine also will work great. For disinfecting the area. Both will not harm the animal. I know the first thing many people think of is the neosporine which probably won't hurt once or twice if put on sparingly. But it does nothing to disinfect the area and clean it. The only thing it will do is soften their scales putting them at risk for further injury or infection. It's really just vasaline with some light antibiotics in it.
