Pete Ramey also invented Pete's Goo, very inexpensive to make, and it works wonders. Wal Mart generic anti-fungal Lotrimen (sp) mixed with equal parts generic triple antibiotic cream. With generics, I use 2 oz of each, it only costs about #4 total. I mix mine in a cheap disposable plastic with lid container. Then I use a butter knife or my finger to load it into a monoject syringe with the curved tip (I snip off the very end to make it easier to squirt out. It gets down deep if you need it to, it works wonders, and one little container of mixed 4 oz of this *Goo* lasts a long time.
White Lightening soaks will kill anything lurking in their hooves better than any other product, is safe, environmentally safe, and will last a long time too making the sticker shock price reasonable. I scrub hooves with blue Dawn, give a 10 minute warm water soak in Davis soaking boots to get all the tiny dirt out of everything, then I mix equal amounts of White Lightening with vinegar which activates it. I use a small 12 oz measure, mix 2 oz of each and soak 45 minutes. I do this once a month in winter because the clay here sticks to their hooves, is slimey when wet and causes nasty problems
