I actually found a 16 oz concentrate bottle of Nolvasan, which is one of the name brands of chlorhexidine, in the Equestrian section at Southern States. I think they also use it to clean horses' mouths or something. Who knows. Either way, it was about $16.99, which lasted me about a year. I probably got anywhere from 8-10 20oz spray bottles of diluted solution for cleaning.Originally Posted by Aza
