I have a Welsh Pony who isn't a fan of his face being touched. I take a handful of treats and stick them in my pocket and then grab a soft, small sponge. After that, I will grab a bucket and fill it up with lukewarm water. Next, I take the sponge and drop it in the bucket. The fourth thing I do is grab some tear free baby shampoo. I apply the shampoo directly to the sponge and, in a small, gentle circular motion, I scrub my horse's brown spots away. When I'm finished scrubbing, I completely rinse the sponge and then take the water in the bucket and careful sponge my horse's face off to rinse the suds away. I try hard not to get soap in his eyes. So far I never had, but that's why I use baby shampoo. I only do this if my horse's face is particularly dirty. Otherwise I just rinse his face with a damp sponge. Good luck!
