I, too, use tide to brighten tails, get cactus out, etc.,. But to wash the whole body you have to be careful. It takes a TINY amount (e.g., a teaspoon of powder to a 5 gallon bucket of water), the suddzing action is off the charts and if ya 'overdo it" it takes forever to rinse it out. It will dry a tail out - so I go behind it immediately with triple moisturizing (human) conditioner...loads of it. Then yeah...its "getting the dirt out" ability can't be beat.
Surprise, shampooing a horse actually dulls the coat. That's why products like Show Sheen sell so well. If you have a shop vac, vacuum the horse. Don't tie it up but hold the lead shank. Use the small furniture brush if it has one. The coat will be clean but not stripped of the natural oils. Then bathe just the lower legs.
If you want something to soften the mane and tail you should try Mane n' Tail Detangler, it works like magic!!! You spray it in, comb/brush through and it's sooooo soft in an hour!!! Hope this helped!!! (: Posted via Mobile Device
