Horse get little hair loss spots from a lot of different things from rubbing to uneven shedding to skin and diet problems. If the skin looks healthy and it's not spreading, I would just leave it alone and not worry about it. If it makes you feel better, I would just wash it with some antibacterial soap and/or betadine and make sure it gets plenty of air (especially if you blanket). Moist, covered skin if a breeding ground for all sorts of bacteria.
