To use as a stop bath it must be white or distilled vinegar. The brown form
may
stain. Check the label as it can be any percentage from 4% to 5% depending on
the brand. Kodak SB-1 for papers is 2% acetic acid, for films the percentage
can be 1%. So if you have the 4% version dilute it with an equal amount of
water for 2%.

Subject: [pure-silver] Using diluted vinegar as stop bath
Hello all,
this was discussed a few years back, but do not remember the details. I have
3
gallons of kitchen vinegar and I remember it was mentioned that a dilution of
vinegar could be used as a stop bath. Does anybody know what dilution of
vinegar to water I should use? Are there any disadvantages to using diluted
vinegar as opposed to the Indicator Stop made by the great yellow Father or
Ilford's Stop bath? If I do use diluted vinegar, how can I tell when I should
dump the bath?
Cheers,
Bogdan
