I don't use CHD much as a primary disinfectant but I do keep in on hand for wound wash if needed. It is a great product and works super well especially if you follow the usage instructions. Like simple green and 99% of the others it needs time to work.
Wisper CHD is harder to get here in Canada it is considered a medical product and is not as easily found on the open market. I believe Robin @ exclusive snakes carries it in Canada, in case you were interested. Personally I use F10SC and as a cleaner I use F10SC XD but there is nothing wrong with the CHD I just don't use that much and like the stability of the f10 once it is diluted.
