Yeah, I use the Chlorhexidine "sorry if spelled wrong" and not the Nolvasan brand. I have a gallon bottle that I have had for about 9 months and is almost empty. About 1 month ago, I went around asking for the chlorhexidine and Nolvasan both, they told me what I had written above???? I have been ordering it via the net.
What ratio do you mix it at?
I have been using 3/4 oz to 32 oz of water and letting sit for about 10 min. then rinsing and drying. This seems to be working good. It would be even better if I could use less.
