White lightning is a product many people swear by. It is mixed with equal parts white vinegar and used as a soak or a gel. It is expensive and if your horse isn't well behaved or afraid of soaking boots, can be difficult. However, it is effective against fungus and bacteria so it can be used to treat thrush as well without hurting good tissue.
Another good and less expensive soak is half water half apple cider vinegar. It also does not hurt live tissue.
A good option is mixing triple antibiotic ointment and athlete's foot cream together and, using a syringe put the mixture into the holes daily.
If you are working with a vet or farrier, they might debride the areas and prescribe a disinfectant agent that needs to be applied daily.
