Okay, my Haflinger mare has a beautiful snow white tail, but she doesn't lift her tail high enough, and it has nasty yellow urine and poop stains at the bottom that will NOT come out. I scrubbed for an hour the other day and it still wouldn't come out. Currently I'm building her a fly swatter attachment(basically a bunch of ribbon and bailer twine all twisted together to go on a wrapped tail) so I can wrap it once it is white(to hopefully keep it white) How do I get this thing white? I have tried softscrub cleaner, dish soap, white n' bright, and regular horse shampoo. Last year before show I cut out all the yellow(it was horribly stained from 2 years of neglect, after scrubbing it was still bright yellow) Then things happened and we had to put her in the cattle pasture(the cattle are really hard on the pasture and it was all mud and manure in places) It stained her tail again, but not as badly. It is still yellow after being washed but is more like blonde hair then sunshine yellow.
Any ideas on how to get it white?
