Maybe wetting them and then sealing in that moisture with the castor oil is causing the scales to remain disfigured or unable to lie down properly? I'm not sure...just spit ballin' on that one. My old boy's gnarly leg is almost all smooth now and I only soaked and washed his scales once before the castor oil treatment....time and the emollient of the oil seems to have wrought miracles. I'm even more impressed with the castor oil for this problem than I am with the Nustock.
