I never really had a problem with this when I was showing (for one, my animals had baths regularly, and 2, half of them were Angus) but what's the best way to get a white switch really white? The classifier is coming Monday to the dairy where I work and one of my jobs for today and to wash all the cows' tails. A lot of them have just had their first bath and a lot of the tails are pretty yellow. What's the best soap to use? I was thinking maybe dish liquid, because that really works well for me when washing to get their hair white. Any other suggestions? I have clear choice and Orvus at my disposal as well as anything that I can find around the house/farm.
