Hose those down with a mild stream of cold water. You can do this 2-3 times a day, to aid in keeping the swelling down.
It probably looks worse than it actually is, because of the swelling. I'm not sure if your vet came out yet, but I hope he left these wounds 'open' (no stitches), because the swelling is going to rip them right out.
As far as what to put on it, you can use Betadine, Nitrofurizone, or any other good wound ointment. Mainly you want to ensure that the flies can't eat at his wounds, so lightly cover\wrap them with non stick gauze pads, and vet wrap.
You may want to do a 7 day series of Penicillin injections as well. The biggest thing that you may encounter is proud flesh, and there are products that can aid in preventing that; Aloe Heal is one good one.
