do a sensitvity test first ...but you can use OXY wash like you use in the laundry...use warm water and add on scoop per 3 gallons of water ...sponge it on the white markings and let it set for a few minutes and rinse ...this works wonders on a horse whith a stained tail and mane that si white or light colored...I used it one my gery arab stud I used to own.
