Is your mare curtrently
nursing? IF so, please contact your vet about this. Otherwise, in my non-
nursing or lactating mares inn the past, I have used only water and an antibacterial soap (i.e. Betadine Surgical Scrub) or only just water. I make sure to soak the areas well with warm water on gentle flow (I also do the vulva area and anus), put a bit of the Betadine on a soft wash cloth and wash all areas gently removing all debris, sweat, and gunk. DO NOT CLEAN INSIDE ANY AREA>..
