I am keeping my ball python in a 20 gallon long Zilla Critter Cage and am searching for a very good cleaner. I have been mixing water and bleach but am getting nervous about the possibility of left over fumes. I have read good things about Chlorhexidine. I've also seen Nolvasan that contains Chlorhexidine......I'm assuming this is basically the same stuff. Anyway what website is the best to get this stuff from? Also, how much do you dilute it with water? Thanks in advance!
