I have a horse with a really thick tail, and it gets greasy and really dirty over time. Yes hers will have the white residue.
I wash it 2 times with soap to get it clean. I really get my fingers in there (much to her delight) and scrub well, rinse really really well. I use a horse shampoo which rinses clean and quickly, or head and shoulders with conditioner. I might try some vinegar next time I wash it. Apple or white or does it matter? Due to her greasy type tail I do not usually condition with a conditioner.
I know there is a baking soda and vodka thread on COTH, but I think I will douse her tail with baking soda in my next tail washing event. Too cold right now (for me) to wash it. This should clean off any residues. I used it on my hair last time and I like what it did. Been a long time since I have used some baking soda on my hair. So why should it not be good for a horse tail?
I get baking soda from costco, I use it on alot of things around here.
OH we do have hard water here in our area.

Dawn Dishwashing liquid - The original blue kind. I like to wash tail with Dawn, let sit a minute or two, and rinse well. Then use a good conditioner, and again, runse well, and end with a vinegar rinse. For the last step, spray in Infusium 23.
I second Orvis as a great general shampoo. Just don't use too much since it's highly concentrated.
I also second Dawn (or any liquid dishsoap, IME) as a great stain and grime buster. That stuff's made to cut through day old lasagna crust, so it certainly can handle a layer of dried pee or whatever your horse has gotten in to. I can't say if it truly whitens, but it certains gets the physical stuff out.
