I have a small container with the solution that I keep using. It's just getting browner. I'll have to look for the pH test kit and check it. </div></div>

I'd be interested in knowing that too because I've used it a lot and it turns brown, then black in no time for me. My parts are all degreased when I dunk them. It gets expensive! I've also noticed that if you leave a part in it too long, it will re-deposit a dark gary oxide back ONTO the part. IT washes right off with something like Spray-9 though.
