Triple antibiotic ointment is my absolute favorite. Good for people, horses, dogs, cats, chickens, etc.
My vet is a big believer in scarlet oil. Any type of an infection that leaves a deep pocket (like when my colt's castration site was infected) he has me swab it out with scarlet oil.
I also like iodine as a disinfecting agent for wounds. I will usually clean a wound with iodine and then put triple antibiotic on it after it's been cleaned.
