One of the reason's they don't use calcium chloride any more, is from the "horsey Folks". and they bring more money than the "alky" burners do, we had to quit using it years ago, because the track we "shared" with the horse's, said it made the horse's hoove's soft, and that was it, no further discussion, end of argument, liquid soap works real good, but the EPA has a thing about "run off", and "wet lands", so that has been banned, of course, it was oil before all of that, and we all know what happened there, so unless someone comes up with something that the "green" folks will approve, it'll be water, and we all know where that is headed! Bob!
