None of those things will kill parasite eggs. If your horse has a white tail that gets stained, the oxy is the bomb. Very, very hot water, mix in a little purple 'old lady' shampoo, then the oxy. Put the tail in the bucket and Shazam, clean, white tail.
You'd probably have better luck with iodine. The surgical scrub stuff, not tincture.
Virkon is good, too. It comes in a little foil pack and you mix it (pink powder) with a bucket of water. It's what they use in animal shelters to scrub everything down.
I love my hand sanitizer and 'wet ones'. But again, that ain't killing nothin'.
