I've been using PMK for a number of years now.
I'm now noticing (and finally becoming concerned with) the percipitation in the mixed Solution B. Which is potassium...something? I can't remember what.
Anyhow, I understand the B solution is heavily saturated. I can never get the solution to mix completely. There's always a considerable amount (as in a film) across the bottom after a couple minutes of mixing. I notice it's been getting worse lately in my case. I do use distilled water. Is this a problem?
