The Vetericyn that stacyj recommended earlier can be sprayed on the wound to disinfect it twice a day, then you can put the antibiotic ointment on it after that dries. Saline or salt water soaked into guaze or paper towel can also be good to clean the wound if you don’t have Vetericyn. Saline or salt solution is made by adding 2 tsp of table salt to a quart of water, and heat to dissolve it.
