If you look at the directions on the bottle of WL it says that it is the fumes not the soaking process. I use a large zip lock bag, put it on the hoof, measure the WL and then add the vinegar and seal up the bag. It needs to say on for 20-30 mins. Your not getting the benefit from just wiping it on.
Ichtimal is great and works even better if you put a Animalintex poultice pad on top and the duct tape up the hoof.
This is from The Horse........full story link posted as well. Thinking has changed when dealing with hoof issues, the "old" style thinking is going out the window.
Forget the foot bath, encourages O'Grady. "As far back as I can remember, soaking the equine foot has played a major role in the treatment of common foot ailments such as abscesses, puncture wounds, corns, foot bruising, and laminitis," he says. "Over the years, I have questioned the therapeutic value of this practice. The principle indication for soaking feet is to soften hard hooves so that it is easier to pare the sole to expose and drain an abscess." O'Grady says there's no question excessive moisture damages hoof wall. "The more the foot is soaked, the more the hoof softens," he says. "The wall begins to flake and separate, and the loss of integrity allows it to expand or bend outward. At the same time, the white line width increases and the sole begins to drop and becomes closer to the ground. As the softening process continues, the horse begins to walk on the sole, creating another source of discomfort." O'Grady says many experts believe soaking damages the foot's protective barrier (periople) and widens the sole-wall junction, which allows more microorganisms to penetrate and further damage the wall. "The softened hoof wall does not hold nails well, so it is difficult to replace or maintain a shoe on a chronically soaked foot," O'Grady says. Instead of soaking the hoof, use a poultice bandage (such as Animalintex) or drawing agent (such as Epsom salts). There are kits with all the bandaging materials fitted for the horse's foot (such as HOOFix), or you can make one yourself The Horse | Healing Hoof Abscesses
