DO NOT USE ALCOHOL on the wounds!! You know how much that stings? Well, the snake doesn't have a clue and won't appreciate it. Alcohol can kill bacteria, but so can Hydrogen Peroxide which won't sting or shock the snake nearly as much. Plus, alcohol has a drying effect, especially on mucous membranes (like the lining in your nose or mouth), if either of these linings become dried out it can lead to greater infections.
I wouldn't recommend doing much with the wound beyond cleaning with warm water to remove the excess pus, bits of dried blood (Leave scabs alone), and dirt/debris.
Then apply Neosporin or Polysporin (or get the generic grocery store brand it should be labeled something to the effect of: Triple Antibiotic) on the wound, including the scabs.
Polysporin contains multiple antibiotic agents so it should be all that is needed. The polysporin itself doesn't heal the wound, the protection from infection combined with it's barrier properties prevent reinfection which allow the body to heal without hindrance. If a scab forms... good...leave it alone. It is the best protection you could hope for and it means the body is doing it's thing. The reason you may want to apply an antibiotic over the scab is in case it becomes dried and cracks and to soften it so that when the new skin forms underneath it will fall off easily instead of being torn off.
Recap: Clean with luke warm to warm water, dry and apply triple anitbiotic. Do this twice a day until healed.
I know I ramble and I apologize if something I wrote doesn't make sense. I can clarify if needed...just ask. And I didn't mean to flip out about the alcohol (it is good for some things and has it's place, but not here). I deal with wound treatment everyday and can tell you this is one of the safest and most effective ways to a fast recovery.
