You are correct, sir. According to the MSDS from Kodak, indicator
stop is between 1-5% acetic acid when properly diluted. The
t 4-5% acetic acid. A
1+1 dilution with distilled water should produce the proper strength
for use. It's much less complicated than overpaying to ship stop
bath.

Sure, go to any grocery store and get Pure "white" vinegar, it's just
acidic acid and water. Probably fewer containments than if
you mix your stop bath with tap water.

Stop bath itself is made up of acetic acid, and an indicator to show
when it's depleted. It's usually shipped in concentrated form, so I
suppose it could be a bit hazardous if damaged/dropped. Not sure where
that line is drawn, though.

Shel,
Because selenium is a pollutant in fresh water
