i have a paint that is about 40% white, 60% brown. i am taking her to her first show soon and i need to get her to stay clean over night. she gets manure all over her back legs more toward the bottom. when i try to get them out with a brush it just makes it a little lighter. the night before the show i am going to spot wash her legs (its winter so i can't give her a full bath) and groom her like crazy wiht green spot remover by cowboy magic. then i am going to put a sheet or cooler on her and put her in the stall (she lives outside) any suggestions on what else i could do to keep her clean overnight?
