Hi midori-chan!
If the wound looks clean and there are no signs of infection (some signs of infection are seepage, fould smell, marked swollenness around the edges, a lump forming underneath), I don’t think you have to do much. You can cut the hair next to it with a pair of small scissors, but if your bun is very squirmy, don’t do it unless there are signs of an infection, in which case you should also clean the wound once or twice daily. If the sore is in a place he can’t reach, you can apply manukka honey on it (if it’s in a place that he can reach he’ll just eat the honey because it tastes like any other honey).
Have a look every day to see so it doesn’t start getting bigger or becomes wet. If an abscess forms (a lump underneath the wound) you’ll need to contact your vet.
Did the mange clear up?
