It may help with some aspects of the solution.
I have not been adding it to mine, as I make my own liquid from scratch. The
few times that I did add some, there was a solid that formed at the bottom of
the bottle. At this point I don’t recall if it was just with some B&S
that was kicking around the studio then, or if I tried it on several samples;
B&S, Formulary, possibly some of Mine, Artcraft, … The solid however,
would NOT dissolve in hot water alone; even boiling water.

What about the addition of EDTA while mixing, or is that no longer
recommended? It has seemed to help mine dissolve.... or it could have
just been the oxalic.
