I'm keeping about 6oz (~180ml) of the etchant in a sealed mason jar; I can see lid's getting corroded, and my first batch of etchant stopped etching after about two uses, which I'm attributing to some kind of contamination. Anyway, I'm not concerned about poisoning myself, my fiancée, or my dogs with this setup; I'm pretty careful with how I'm handling this stuff. The first time I did any etching, I did open a window and used a fan to direct any fumes toward the window. I think that was a good thing, but I forgot to do it the 2nd time I made boards.
HCl and H2O2 doesn't keep!
