QMix is a mix of 17% EDTA and 2% CHX. According to JOE it does work the same as EDTA when it comes to smear layer removal. I think it is a nice product, but costly. I just use EDTA and then CHX as separate steps. Advantages of my way is cheaper and don’t have to rinse out NaOCl with sterile water before EDTA by itself. There is some disagreement as to what exactly the precipitate is that is formed when NaOCl and CHX mix, but it’s likely not good for patient whatever it is.
I didn’t buy.
