If you use Vetricyn Hydrogel, it acts as the ointment without attracting dirt. It sprays on and then dries to the skin, coating it. Ointment will stay moist and then everything sticks to it.
Most farm supply stores carry it, pretty sure it's on Amazon too. The all-species vetricyn hydrogel is fine, no need to get the "poultry" version. There is a disinfecting spray as well which many of us use and have on hand, but for this, make sure you have the "hydrogel". A little goes a long way.
If you scroll down past the first part with the order sheet (again, you should be able to find it locally without a problem), just past the informational video, it will give features - and then scroll down for a bunch of reviews with pictures of critter wounds people have treated using it.
