Bleach works well. I dilute, spray, and then put foot down. I am not soaking hoof in it, nor pouring it on like dousing a fire.
One reason that the home remedies are being given such a bad rap, is that the companies that make the "new methods" do a hell of a lot of advertising, as well as give incentives for their products to be recommended by vets/farriers.
Latest thing is NO Pepto Bismol, when it too has been used and recommended by vets for years. Now? OH MY GOD....go buy the expensive med from vet.
Money makers many times.
I've used bleach over 50 years, as did most I know. It does work, and usually with one application too.
And never, ever had hoof problems from it, and I've used it on show horses, TB's, and every thing in between if needed it.
Horses make me a better person.
