I like Spectrasan, also known as HoofRX. It's a chemical-free disinfectant that does not harm healthy tissues.
As a preventative, I like ACV. Also all natural and doesn't kill healthy bacteria like bleach will.
I also find that the best thing you can do for your horses feet is pick them every day. It gives them a chance to "breathe" for a bit and you can see any signs of thrush or overgrowth pretty much the moment it happens. That and it helps train the horse to pick up his feet for the farrier. Posted via Mobile Device
