Continue to do what your doing. You may want to take a damp paper towel and blot the spot every so often to soften the scab so that it will fall off on it’s own. It may take longer for that spot to heal but what you’re doing is fine.

Stop playing with it, just leave it alone, as above says don’t irritate it. I’d even stop putting any kinda ointment on it at all now, just wash it when you wash the rest of your body as normal. It should be well recovered by now and keeping the area moist will not help prevent any infection at this stage, probs the opposite. Just treat it like any other graze you might get andf forget about it for a while.
