I'm not sure about that.
The CuCl is just sitting there, waiting for me to drop in a board all
year round. It doesn't go bad or require me to mix up a new batch.
Maintainance is minimal, and can be done while the board is etching
which is efficient use of time.
I can still see through my CuCl with a bright light from the other
side, but now the tank is positioned inconveniently for that and I
lift the board out for final inspection.
