Definitely the cowboy magic detangler for manes and tails. The vetrolin detangler is also EXCELLENT (the gel that is similar to cowboy magic) but it seems to be difficult to find. Last time I looked, Dover was the only place I could find it (ie not at Judy's or Champions etc at the horse show)
The healthy hair care pink stuff, diluted way down and rubbed into the coat with a towel is nice. It can attract dust so make sure not too much pink stuff to water ratio.
If youre one that likes to put stuff on the feet before a bath, effol is good. For the show ring, fiebings.
For tack cleaner we mix small parts murphey's oil soap, leather conditioner, and the rest water to make a spray. For conditioning, I like the Devoucoux and Antares conditioners.
Yes I also found that the trick is that you HAVE to rub it in, you can't just spray it on and let it sit.
Adversity is the stone on which I sharpen my blade.
Favourite Coat conditioner: None. I just use lucky braids shampoo
Favourite hool oil: Argent hoof - all natural and works wonders on preventing thrush
Favourite tack soap: Regular ol' glycerin soap and Antares tack conditioner to finish (smells uh-mazing and doesn't leave tack tacky...)
