Something I've used lately to make my bathroom cleaner and cut down on
fumes, as well as the amount of chemistry I'm using, is to hand-process
in a 5 reel 35mm still tank. The results are uneven (a plus in my
mind), but I can mix about 2L of chemistry and stuff 100ft of 16mm in
there. I'm guessing the cross contamination of chemistry is a major
issues, I don't keep chemistry around very long and I extensively clean
the processing tank in between batches.
