One of my mares has the grossest tail you could see. Its caked with mud, pee (she's also in heat so its particularly nasty atm), poo (she has a thick tail that is always in the way of her business), and to top it all off it has pitch from the pine trees in it. **yay** LOL.
My gelding has almost the same problem but without the pee.
Any ideas on cleaning it? I'll probably end up washing it if I can't get anything else to work but its a bit chilly for that this time of year .
