Okay, so I decided to use Nolvasan for my spot cleaning. I went to the tractor supply store and picked up :http://www.drugs.com/vet/nolvasan-s.html this was all they had (FYI: it was like $18 for a Pint). It is Nolvasan S, Chlorhexidine discetate, scented disinfectant, active ingredient: 1,1'-Hexamethylenebis [5-(p-chlorophenyl) biguanide] 2%.....Other inactive ingredients:98%. Can someone tell me if this is the Nolvasan that everyone uses? And if the ratio to cut it is: 1oz. Nolvasan to 1 gal. water? Thanks for the help!!!
